Project Report for the

Habitat for Humanity International

20th Anniversary Blitz Build

Construction Materials Management Program

Americus, Georgia -- September 1996

Project Objectives

• demonstrate feasibility of a construction materials management program during an accelerated build.
• provide contacts for the Sumter County Habitat for Humanity affiliate to continue a materials management program year-round. This program will demonstrate a developed model of materials management for Habitat affiliates nationwide.
  
  

Summary

A "curbside" materials management program (MMP) was developed and implemented by the HFHI Department of Environment (HFHI DOE) and the Sumter County Habitat for Humanity Affiliate (Affiliate) in cooperation with the National Association of Home Builders (NAHB) Research Center through funding provided by the United States Environmental Protection Agency (US EPA) Urban and Economic Development Division. Approximately 80 percent of the waste material was diverted from the landfill.

The MMP was developed for the Habitat for Humanity International 20th Anniversary blitz build (Blitz) in Americus, Ga. One recycling designate (Site Contact) from each of the 20 house crews monitored site-separation of materials, and assisted with material collection when necessary. A core recycling crew (MMP Crew) of three people, equipped with a 14-yard flatbed truck and a 10-yard dump truck, collected the separated recyclable materials from the curb and delivered them to local reuse or recycling outlets. The city of Americus (City) collected and hauled all other material. A permit was obtained from the Georgia Department of Natural Resources to grind the scrap drywall (50 percent, by weight, of the total waste stream) and site-apply the pulverized material as a pre-sod soil amendment.

Program Development: May 1996 through August 1996

Project Team

The MMP Project Team consisted of three people: Emily Keyes of the HFHI DOE, Steve Zulkosky of the Affiliate construction crew, and Eric Lund of the NAHB Research Center.

Program Coordination

Communication between the MMP Project Team and key Affiliate personnel was essential. The key contacts within the Affiliate were the executive director, the construction supervisor, and equipment operators (forklift and dump truck). Clear individual and team role definition was critical though often difficult to determine. It was decided that the MMP Crew would be responsible only for the materials being recycled. All other waste material (i.e. general waste) would be collected by the Americus Solid Waste Department (the City). The MMP Project Team was not responsible for any aspect of general waste collection.

The Affiliate provided access to important information such as:

• site map--to determine site accessibility, pick-up routes
  
• materials list--to determine type of waste material generated on sites
  
• construction schedule--to coordinate stages of construction with material pick-up schedule
  
• vehicle availability--to schedule material pick-ups, to help determine appropriate type of containers, to estimate the number of pick-ups necessary for each material, and to estimate human resources needed
  
• general waste collection schedule and hauler contacts--to coordinate recyclable material pick-ups with general waste pick-ups, to inform the hauler of the MMP and to clarify what is "general waste" and what materials are being recovered for recycling and reuse
  
• access to volunteer applications--to recruit volunteers for MMP
  
• access to storage space--in case materials needed to be stored during or after the Blitz before being hauled to the outlet

Waste Quantity/Type Assessment

Prior to the Blitz, two Affiliate construction sites were monitored for waste material type and quantity. The data compiled from the monitoring along with NAHB empirical data was used to estimate the quantity of waste expected during the HFHI 20th Anniversary Blitz Build. The results follow:

		PER HOUSE WEIGHT (lbs)
		Monitored Site Average	Blitz Projection
Material
Wallboard		1436	1200-1600
Wood		432	500-750
untreated		384
treated		48
Cardboard/Paper		111	150-250
Metals		20	40-50
Fiberglass Insulation		0	0
Vinyl Siding		150	120-150
Rigid Insulation		7	12.5-17.5
Asphalt Shingles		289	250-300
Floor tiles		90	30-40
Trash		180	200-250
	TOTAL	2732	2500-3400

Waste Reduction

Avoiding the generation of waste is important in a waste management effort. The amount of waste generated is reduced by house designs that minimize the amount of material cut-off required, and by careful ordering to assure that appropriately dimensioned material and the appropriate quantities of material are delivered to each site.

 

The Project Team was not able to review house plans because Blitz planning was too far under way at the time the MMP development began. However, the plans that the Affiliate chose for the Blitz, taken from the Habitat Planbook, already reduced the potential for waste generation due to their modest size and simple design. These simple designs, if coupled with careful material ordering, would significantly minimize the amount of material delivered to the site, and therefore the amount of waste generated. Unfortunately, the MMP did not have input into the estimating phase of planning due to limited time. The HFHI DOE recognizes waste reduction as a priority for future material management projects.

Locating Material Outlets

The NAHB Research Center networked on the national level for material outlets. HFHI DOE and the Affiliate networked through local outlets and made final contact and negotiations with the outlets. The following information was considered when making final decisions:

• quantity of waste expected--Outlets need to know the quantity of material expected to determine if they can/are willing to accept it. The Project Team also considered the amount of waste material expected as compared to the ease with which logistical details could be planned. This helped to prioritize tasks.
  
• containment and preparation requirements of the outlet--Outlets vary on these requirements. For instance, some require that the material be kept clean and/or dry, be cut into uniform lengths, have nails removed. Some want the material contained, while some allow it to be dumped in a pile. The Project Team considered if it was possible to adhere to the requirements of the outlet with the available resources.
  
• location/distance to the outlet--How far is too far?
  
• end use of the product--The ideal end use varies depending upon the objective of the MMP. In this case, the ideal was for the material to be used in its most intact state. Amount of logistical planning and potential income from the sale of the material were also factors.
  

The Project Team found it necessary to entertain several options for material outlets simultaneously because the best, most feasible option is dependent upon several aspects of program development. For example, when searching for an outlet for the ground drywall, the Project Team considered selling gypsum to local farms (peanut farmers normally apply pure gypsum to the soil) while pursuing a permit from the state of Georgia that would allow the ground gypsum to be applied on site. Both of these options entailed unique logistical challenges and facilities/equipment requirements. However, it seemed best to keep all options open until finalizing one.

Wallboard Grinding

Regulatory and logistical issues surrounding the wallboard grinding consumed much of the Project Team efforts. The NAHB Research Center spearheaded the effort to develop a proposal for the Georgia Department of Natural Resources and to ascertain information regarding the appropriate grinding equipment.

State permitting is required to avoid the potential abuse and/or misuse of this practice and to protect the soil from substances that may be harmful. The proposal for permit needed to include:

• statement of the beneficial effects of applying ground wallboard to the soil, supported with documentation--In this case, it was shown that the gypsum would increase the root penetration of the sod, and would also add calcium and sulfur to the soil. Documentation came from a report by the U.S. Department of Agriculture submitted to the National Gypsum Association.
  
• application rate--This is the ratio of available land to the amount of ground gypsum expected. In this project, the application rate was determined backwards. The amount of sod ordered was used to indicate the square footage of land on which the gypsum powder could be applied. Then, the amount of gypsum powder that could be applied to that land within the accepted application rate was determined. (The application rate was not to exceed 10 tons per acre as suggested by the USDA report?). This indicated the maximum amount of gypsum powder needed.
  
• soil types of the sites--The site soils were high in clay content, and thus would benefit from gypsum application.
  

For a summary of the USDA report findings, please see "Letter of Support for Agricultural Uses of Wood and Drywall"--Appendix A . For more information or a copy of the USDA report, contact the Gypsum Association, 810 First Street NE, #510, Washington, DC 20002 or report author Ronald Korcak at USDA, Plant Sciences Institute, Bldg. 003, room 232, Beltsville, MD 20705-2350.

 

Logistical details of acquiring the appropriate grinder for the sites also needed to be worked out. These details depended on the number of sites served (in this case 20), accessibility of those sites (in this case accessibility was limited ), cost and availability of a grinder. Though a mobile, low-speed grinder would have been ideal for the scattered layout of the Blitz sites, cost and/or availability of these grinders did not allow their use. Instead, the use of a large, stationary tub grinder was donated by TransWaste, owner of the local landfill. The tub grinder was located at the local landfill approximately five miles from the Blitz sites.

Assessing Proper Material Containment

Some materials needed to be contained on site. Others, such as wood and drywall, simply needed to be stacked on the ground. However, the proper containment for each material was dependent upon many factors. Following are some of those factors and relevant questions:

• estimated volumes of material--How much scrap is expected and what size container, if any, is needed to hold that amount?
  
• methods of loading and unloading--Will the material be loaded by hand or by forklift? If it will be loaded by forklift, stacking it on scrap wood or pallets is necessary. If it is to be loaded by hand, containing the material in liftable bins may be advisable.
  
• vehicle availability--For example, if a dump truck is available, off-loading the material will be easy. However if some other type of vehicle is being used, it may be advisable to keep material contained within the truck so as to facilitate off-loading.
  
• outlet requirements--Some outlets may require the material be contained when it arrives at their facility, or they may allow it to be dumped.
  
• types of containers available--The Project Team tried to work with what was available to avoid purchasing containers. The Project Team also considered what resources would be available on site. For example, large appliance boxes can be used for cardboard scrap, etc.

In this project, final decisions on containment were made the first day of the Blitz. Though it is an important aspect of the program, it is one that has some flexibility.

Signage

Signs to indicate separation areas for each recyclable material were constructed of scrap cardboard cut 1 ft x 4 ft and posted on 3-foot stakes. Sign construction was time-consuming and took one person several days to complete. However, signs could not be completed until material categories were determined and material categories depended on outlets chosen. In this case, signs were prepared several weeks before the Blitz and then a day or so before the Blitz they were painted with material categories.

Public Awareness

Many efforts were made to get the word out about the MMP:

• A press release was disseminated by the HFHI Media Department.
  
• MMP information was included in volunteer manuals.
  
• A large program sign describing the program, its benefits, and asking for participation was placed near the food tent.
  
• The affiliate executive director addressed the volunteers as a group and explained the MMP.
  
• MMP T-Shirts were given to each Site Contact and worn by the MMP Crew.
  
• Material containment areas were clearly visible on each site, providing a constant reminder to separate materials, and indicating to observers that materials were being recycled.
  

Program Implementation: Aug. 30 - Sept. 10, 1996

Overview

Personnel/Vehicles

A core group of three people worked full time on the MMP Crew_ and were responsible for setting up material collection areas, orienting the Site Contacts to the program, collecting the separated materials from each site and hauling them to the appropriate outlet_. Each construction site designated at least one person, the Site Contact, to be responsible for monitoring the separation of materials at the site, acting as the MMP Crew liaison, and assisting with material handling when necessary (see Site Contact Role Description--Appendix B). The Crew had week long access to a 14-yard flatbed truck, and a 10-yard dump truck. A forklift and operator were available off and on throughout the week.

 

Collection Areas

Most house sites required individual material separation areas because sites were scattered over several blocks. A few houses were close enough to share one collection area. The material collection areas were cordoned off on three sides (where feasible) with surveyor tape and signs were set indicating areas for each recyclable material and general waste. Several factors were considered when siting the collection areas. To the extent possible, they were located:

• close to the road--to facilitate loading materials onto truck
  
• out of the way of work areas and vehicle paths--so as not to hinder the construction process, and to ensure safety
  
• close to the house--to facilitate material separation by the house crew

Materials Containment/Handling

The recyclables were handled as follows:

• untreated wood and cardboard--Piled loosely on the ground. Hand-loaded onto the truck and delivered to Koinonia Partners, a local self-reliant community. The cardboard was used as mulch in the organic garden and the wood was reused or burned for cooking fuel.
  
• wallboard--Stacked on pallets and/or scrap wood. Loaded with a forklift into the dump truck. The drywall was transported to the local landfill where it was ground with a tub grinder and delivered back to the sites. The pulverized gypsum was raked into the soil at each house site before landscaping. The application rate was roughly 10 tons/acre. The construction sites generated more drywall scrap than could be applied on-site within the acceptable application rate. The remainder of the pulverized drywall was donated to a local farmer.
  
• metals and vinyl siding--Contained in 30-gallon bins or garbage cans and hand loaded onto the truck. Both materials were stored at a warehouse until after the Blitz. They were then delivered to local outlets in Albany and Richland, Ga.
  
• carpet padding-- Piled on the ground or contained in cardboard boxes and loaded onto the truck. The carpet padding was stored at a warehouse and delivered to Richland with the vinyl siding.
  

The vinyl siding and carpet padding scraps were accepted by Redmond Homes, a manufactured housing facility. Redmond Homes has a comprehensive waste management program and donated the use of its collection facilities which are serviced by a plastics recycler in Columbus, Ga.

Documentation

Throughout the week, logs were kept of material pick-ups and material deliveries. The logs allowed the MMP Crew to monitor servicing status of each site and to note observations such as whether a site needed another bin for wood scraps, or if the site needed another drywall pick-up. The delivery log was used to keep track of volume estimates, as well as time needed to complete a route, transport materials, and off-load.

Results

The quantities of the material listed below were based on the volume of the trucks. Weights were determined by volume/weight conversions and are estimates only.

Material	Generated		Diverted
	Cubic Yards	Tons	Cubic Yards	Tons	% Vol.	% Wt.
Wood Untreated Treated	40 8	6.5 1.6	34 4	5.5 0.7	85% 50%	85% 44%
Drywall	100	15	100	15	100%	100%
Cardboard	50	1.9	42	1.6	84%	84%
Metals Ferrous Non-ferrous	1.5 1.5	0.07 0.05	1.5 1.5	0.07 0.05	100% 100%	100% 100%
Plastic Vinyl siding Carpet padding	13 2	1.3	13 1	1.3	100% 50%	100%
General Trash (asphalt shingles, rigidinsulation, plastic wrap, etc.)	50	2.25	0	0	0%	0%
Total	266	28.7	197	24.2	74%	84%

As the table shows, approximately 80 percent of the waste material generated was diverted from the landfill. Drywall scraps accounted for approximately 50 percent (by weight) of the waste stream, and the wood and cardboard together represent another 25 percent. Vinyl siding and metals accounted for the final 5 percent.

As shown, recovery of some materials was less than 100 percent. The MMP Crew was short handed and therefore was required to prioritize material collections. For instance, toward the end of the week, collecting the rest of the treated lumber was not as much of a concern as collecting the scrap vinyl or drywall. As a result, only half of the treated lumber scraps were recovered. Second, miscommunication with the City, which was responsible for hauling the general waste, resulted in two sites being cleared entirely of all scrap material.

For this Blitz Build event, the City donated its forces and waived containment rental and collection/hauling fees. The waste removal charge was simply the $38.40 tipping fee charged by the privately owned landfill. Therefore, diverting the recyclable materials from the landfill avoided a cost of $929.28.

Key Observations and Suggested Improvements

Volunteer cooperation

Volunteer cooperation was excellent. Volunteers at a great majority of the sites conscientiously separated the materials and anticipated MMP Crew pick-ups. Continual communication by the MMP Crew with the Site Contacts was essential although time-consuming. This dialogue allowed the MMP Crew to update the Site Contact daily, and to give support and feedback. Announcements regarding the MMP by the Affiliate executive director at volunteer meetings and inclusion of MMP information in volunteer manuals (see Volunteer Manual Insert--Appendix C) integrated the MMP into the operation of the Blitz, thus encouraging and supporting volunteer cooperation.

Vinyl recovery

Use of the original vinyl boxes (or a half-box) to collect and contain the vinyl scraps would have been more successful than the 30-gallon plastic bins.

Reuse Pile

A designated reuse pile at each site would have been an efficient way of separating materials to be used at later builds from those to be recycled or discarded_. The reusable material could be collected during Blitz cleanup or, if necessary, throughout the week. Available space is a factor to consider as is vehicle and human resources available to make the pick-ups. Separating recyclable materials at each site provides the opportunity for on-site reuse because the materials are easier to locate.

Space/Accessibility

Successful separation of materials was difficult due to crowded construction sites. Crowded material separation areas cause the materials to mix. This could be addressed by frequent servicing of small sites; however, this strains the already limited time of the MMP Crew. Site access was limited to only small or highly maneuverable equipment because of narrow streets and minimal space on site. With greater access, alternatives such as 30-yard roll offs could have reduced the time devoted to the drywall recovery by providing a central collection/hauling facility.

Time, Human and Vehicle Resources

Avoiding bottlenecks in the construction schedule is critical in a Blitz. Thus servicing the sites on time and staying ahead of the waste generation was essential. This proved very difficult with only three people on the MMP Crew, especially toward the end of the week as drywall collection, processing, and distribution was time-consuming and vehicle-intensive. The MMP Crew was short-handed and could have used an additional three people throughout the week. Week long access to a forklift also would have increased efficiency. (For a general overview of MMP pick-up schedule, see MMP Schedule--Appendix D)

Coordination

The MMP would have been more successful with more consistent internal coordination with the Affiliate. Decisions and schedule changes made by the Affiliate both before and during the Blitz affected the MMP. Close coordination with the Affiliate is the key to efficient use of time, vehicle and human resources. The MMP cannot be a separate initiative that complements the blitz but an all-inclusive, integral element of the blitz effort. Closer coordination also could have facilitated more waste reduction. With input into the design/estimating phases of planning, the amount of waste generated would have decreased.

Final Recommendations

Integrate the MMP into the planning and operation of a Habitat Blitz Build

The success of the MMP could be greatly improved by incorporating it into the fabric of the Blitz planning efforts. Following are several key steps to accomplishing this:

• A Committee
  

Establish the MMP Project Team as a committee within the Blitz planning structure. This committee must work closely with the construction supervisor as the work of the Project Team is dependent upon decisions made regarding the Blitz operation. The committee should consist of no fewer than three people and should be available to begin planning several months prior to the Blitz.

• An option for volunteers
  

Include on Blitz applications the option for volunteers to participate as either Site Contacts or full-time MMP Crew. This would establish the MMP as an integral part of a Blitz event, thereby strengthening Habitat's environmental accountability.

 

• Integrate into all Blitz printed material
  

 

 

Include daily tasks and guidelines related to the MMP in the Crew Leader and House Leader Manuals. Such as:

• designate an MMP site contact from your house crew
  
• explain MMP objectives and recyclable material categories
  
• locate the materials collection area
  
• stack scrap drywall on pallet so that it may be lifted by fork
  
• cover drywall with plastic every night
  
• contain vinyl and keep it relatively clean
  
• rake in pulverized gypsum before laying sod, saturate with water before and after sodding

 

 

Including this information once again incorporates the MMP into the fabric of the Blitz planning. It also alleviates some of the MMP Crew responsibilities and makes more efficient use of their time.

 

Develop Materials Management Program during the normal construction schedule/ Complete Economic Analysis of the program

The Affiliate should assign one or two full-time volunteers to develop the recycling program for the affiliate's normal construction schedule, thereby creating a recycling atmosphere year-round. Included in this program should be an economic analysis of the Habitat-specific recycling program. Material management can save money and natural resources but it is difficult to determine how much of either. Without that information, it is difficult for affiliates to feel justified in spending the resources to develop such a program.

The Americus Recycling Project Team responsibilities would include contacting outlets, acquiring bins, educating volunteers and staff of the program specifics, monitoring program success, tracking expenses and incomes, documenting decision-making and obstacles. This material management program should closely document the economic factors encountered and considered during the program development and throughout its implementation.

The chart on the following page provides contact information for material reuse possibilities, and outlets local to Americus, Ga. The National Recycling Coalition (703/683-9025) is a fantastic resource for information on recycling outlets in locales across the country. The NAHB Research Center's publication Residential Construction Waste Management: A Builder's Field Guide is another great resource (call 301/249-4000 to request a copy). Also, the Manufactured Housing Institute (703/558-0400, Kami Watson), can provide names of MHI members in a particular area that may offer the use of their recycling collection facilities.

Appendix B--Site Contact Role Description

Materials Management Program

Thanks for volunteering to be a Site Contact for the Materials Management Program. The following information should answer some of your questions.

What do I have to do?

• Be the resource for your house crew. That means you need to be familiar with what materials are being recycled, what materials are waste, and when to expect a pick-up. (That information follows).
  
• Be the contact person between your house crew and us, the materials management crew. If someone on your crew has a question regarding materials management that you can't answer, contact one of us. If the materials are piling up and are getting in the way, let us know.
  
• Monitor site separation of the materials by keeping an eye on the materials collection area. If materials aren't being properly separated, then
  
• Remind your crew to place materials in the appropriate area or bin and/or clarify which materials go where.
  
• Anticipate the Materials Management pick-up visits. Since we will be loading materials by hand, we will occasionally need help from each house crew, particularly during the drywall pick-ups.

What to separate and what to dispose?

All areas or bins will be clearly indicated with signs.

	Separate	Dispose	Includes:
Untreated Wood	X		pine, spruce, plywood, OSB, casing, baseboard, closet shelf scrap
Treated Wood	X		all treated lumber
Drywall	X		all drywall scraps, any size, please use tarp to keep as dry as possible
Cardboard	X		corrugated cardboard, brown wrapping paper, paperboard
Metal	X		aluminum cans, aluminum scrap, lumber ties, facia, etc. No nails.
Vinyl siding	X		all vinyl siding products, including J-channel
Carpet padding	X		carpet padding only. No carpet scraps.
Insulation	X	X	fiberglass scraps can go in attic, rigid board in crawlspace. Dispose rest.
			carpet scraps, vinyl floor tiles, asphalt shingles and all other materials
General Waste		X	that do not fit into the above categories such as caulking tubes, paint
			cans, rubble, cellophane and plastics, etc.

When will the materials be picked up?

Following is a tentative pick-up schedule for the recyclable/reusable materials. General Waste will be picked up separately. If your site needs a materials pick-up outside the scheduled time, please contact someone on the Materials Management Crew.
(Pick Up Schedule attatched as Excel File)

A note about Drywall:
The scrap drywall will be pulverized into a powdery material and applied to each site before the sod is laid. (It is important that the drywall scraps be kept as dry as possible). The appropriate amount of pulverized drywall will be distributed to each site before Saturday morning. A Materials Management Crew member will demonstrate to you the appropriate method for raking in the drywall. You can then demonstrate this method to the other members of your crew.

Materials Management Program

Construction Materials

The construction of 20 homes during the Blitz will generate approximately 30 tons of
waste material. About 80 percent of this material will be recycled or reused as part of a materials management program. An area will be designated at each site where the indicated materials
should be collected separately.

	Separate	Dispose	End use
Untreated Wood	X		donated to Koinonia farm for firewood
Treated	X		re-used as stakes, or used by the HFHI Craftshop
Drywall	X		pulverized and applied under sod as soil amendment
Cardboard	X		donated to Koinonia farm for use as mulch
Metal	X		recycled into metal products
Vinyl siding	X		recycled into plastic products
Carpet padding	X		recycled into more padding
Insulation	X	X	To the extent possible use in house. Dispose the remainder.
Carpet scrap		X	While some of these products are recyclable, recovery is unfeasible
Vinyl floor tiles		X	due to either small quantities, or a complicated recycling process.
Asphalt shingles		X	Combined, these materials will compose about 20 percent of the
General waste		X	total waste stream. Please pile them together in the designated area.

Food Materials

Feeding 700 volunteers over a six-day period generates a great quantity of waste, most of which is locally recyclable. Students from Americus High School, as a part of their environmental science class, have developed a program of food materials management. Please separate materials into
the appropriate bins.

	Separate	Dispose	End Use
Aluminum cans	X		recycled into aluminum cans
Glass	X		recycled into glass products
Napkins	X		donated to Koinonia farm
Brown paper bags	X		re-used, eventually recycled into paper products
Cardboard/paper	X		donated to Koinonia farm for use as mulch
Food scraps	X		donated to Koinonia farm
Wax paper		X	Recovery of these products is unfeasible due to the small quantities
Plastics		X	and/or the complicated recycling process. Please place these
Cellophane		X	materials in the designated "trash" receptacle.

If you are interested in helping with materials management throughout the entire blitz, contact your house leader, or Emily Keyes (program coordinator) at the Materials Management station.
