In the United States, construction and demolition debris (the waste produced in the course of constructing, renovating, and demolishing buildings) accounts for 10 percent to as much as 30 percent of the total municipal waste stream. This debris is composed of excess building materials that contain valuable resources and embodied energy from their production and transportation to the jobsite. Once materials have been consigned to the landfills, these resources are virtually impossible to recover. Recognizing and fully utilizing building materials' value is the foundation of construction waste management. Both architects and contractors can greatly impact the amount of construction waste generated on the site.

Construction waste management is the process of planning and implementing the handling and disposal of building materials on a construction site. It involves applying the conservation hierarchy: reduce, reuse, and recycle to construction materials and methods. Research, training, and development of a construction waste management plan are integral parts of this process.

Eight thousand pounds of waste are typically thrown into the landfill during the construction of a 2,000 square foot home. Most construction waste goes into landfills, increasing the burden on landfill capacity and operation. Waste from solvents or chemically treated wood can result in soil and water pollution. Reusing and recycling materials, instead of landfilling them, extends local landfill life, preserves natural resources, reduces pollution, and saves energy.

Thorough planning is the key to a successful construction waste management strategy. However, planning starts well before any materials are ordered or need disposal. The building's architect should base the design on standard sizes and materials to eliminate waste on site. For instance, designing walls to use full sheets of drywall instead of having to cut sheets eliminates both time in cutting the material and the resulting waste.

In general, using scraps throughout the construction process can save money and allows materials to be used efficiently. Additionally, using high quality materials to produce engineered products, such as finger-jointed studs, reduces rejects. This approach can reduce the amount of material needing to be reused or recycled and bolster profitability and economy for the builder and customer.

Another key element to consider is the training of construction workers. Workers should be instructed on material use and handling and waste minimization. Materials will be received and handled differently on site, when using a construction waste management plan. On site separation of reusable and recyclable materials from other materials will require training, signage, and follow-up. Bins must be monitored periodically to prevent waste mixing as a result of crews or passersby contamination. However, once separation habits are established, on site separation can be done at little or no additional cost.

Many construction materials that are still usable can be donated to nonprofit or other material reseller organizations. This keeps the material out of the landfill and allows the embodied energy of the product to be retained.

Construction waste management does not include hazardous substances such as asbestos, lead, PCBs (Polychlorinated Biphenyls), mercury, radioactive materials, and CFCs (chlorofluorocarbons). These materials need to be handled by trained hazardous materials specialists. Improper removal and disposal can result in extreme human and environmental health impacts.

Reduce Consumption and Waste

The first step in the conservation hierarchy is to reduce or minimize both consumption and waste. Reduction involves minimizing excess and leftover materials as well as doing more with less. For instance, using concrete as a finished floor instead of tile eliminates the need for both the tile and its adhesive. Careful storage of materials away from weather and pilfering to prevent loss is a waste minimization strategy.

Setting Goals and Incentives

Setting goals is necessary groundwork for a successful construction waste management plan. Establishing construction waste management goals for a project allows results to be measured and communicated. In order to garner greater participation, establish incentives such as hardhat stickers, t-shirts, and snacks/meals for workers who excel at meeting construction waste management goals.

Reuse

The next step is reuse, which involves finding another use for leftover and surplus materials either on or off site. It includes reusing excess materials on site or selling/donating materials to a used building materials supplier or salvage company. Reuse can also be applied to materials that were salvaged during deconstruction/demolition or remodeling projects. These materials can be stored for use on site or sold/donated for use by a third party.

The contractor should designate an on-site party (or parties) to be responsible for instructing workers, overseeing, and documenting results of the construction waste management plan for the project. Additionally, construction waste management goals and results should be discussed at all on-site gatherings including pre-construction, weekly project, and safety meetings.

Waste Minimization/Reduction and Reuse Guidelines

General

The Contractor and Subcontractors should exercise the following waste minimization practices to the greatest extent possible:

• Careful takeoffs and tight ordering
• Return of over-ordered materials to supplier (if not required by owner for maintenance and repairs). If a supplier will not take materials back, donate leftovers (see Resources section below).
• Careful installation to avoid tearing out and redoing
• Use of centralized cutting area(s) to facilitate the use of cutoffs rather than cutting into new material when only a small piece is required (studs, gypsum board, insulation, etc.)
• Proper on-site storage of new materials to prevent damage

Cardboard and Paper

Avoid excessively packaged materials and supplies. However, be sure packaging is adequate to prevent damage and waste.

Minimize the number of blueprints and reproductions necessary during the design and construction process.

Drywall

Order drywall in optimal dimensions to minimize cut-off waste. Drywall is available in different lengths, and designed dimensions should correspond to standard sizes.

Large drywall scraps can be set aside during hanging for use as filler pieces in areas such as closets.

Although technology does exist for recycling drywall into textured wall sprays, acoustical coatings, gypsum stucco, fire barriers, or agricultural products, there are currently no local markets. Large pieces of drywall (full to half sheets) can be donated (see Resources section below). Some composting operations want to use gypsum from the drywall as a soil amendment.

Reuse joint compound buckets for tool or material storage by clients or crews.

Insulation

Install leftover insulation in interior wall cavities or on top of installed attic insulation if it cannot be used on another job.

Lumber

Optimize building dimensions to correspond to standard lumber dimensions.

Modify framing details to optimize lumber use and reduce waste and inform the framing contractor of your plan.

Develop detailed framing layouts to avoid waste when ordering and cutting lumber.

Store lumber on level blocking under cover to minimize warping, twisting, and waste. Avoid losing scrap wood in soil; it can attract termites to the building.

Set aside lumber and sheathing/composite board cut-offs that can be used later as blocking, spacers in header construction, etc.

In remodeling, evaluate whether salvaging used lumber is possible.

Save small, untreated wood scraps to use as kindling for clients or crewmembers.

Larger pieces of leftover lumber (6' or more in length) can be donated (see Resources section below).

Save clean sawdust for use in compost piles or around gardens. Avoid sawdust that might contain painted or treated wood. This should be bagged separately. Untreated bagged sawdust may be donated (see Resources section below). Minimizing sawdust and small wood scraps from getting buried in the soil also reduces the attraction of your site to termites.

Masonry

Estimate masonry material needs carefully to avoid waste.

During construction, collect, stack and cover brick and other masonry materials to prevent soiling or loss.

Clean concrete chunks, old brick, broken blocks and other masonry rubble can be buried on-site during foundation backfilling.

Salvage usable bricks, blocks, slate shingles, tile and other masonry materials from remodeling and construction. Store for future jobs or divert to salvage operations (see Resources section below).

Check to see if your masonry supplier will accept the return of materials in good condition.

Metals and Appliances

During remodeling, separate old appliances and metal building materials, such as aluminum siding and roofing, metal ductwork, and conduit for reuse.

Consider holding a salvage sale of usable items during the construction process.

Miscellaneous

Branches and trees from land clearing can be stored separately and chipped for use on site to create landscaping mulch. Composting operations also will accept branches and trees.

Old nickel cadmium batteries from portable power tools should be disposed of properly (see Resources section below).

Donate clean, reusable building materials such as cabinets, doors, windows, tile, wood, plywood, drywall, light fixtures, bathtubs, sinks, mortar mix, hardware, latex paint, nails, screws, electrical and plumbing supplies (see Resources section below).

Paints, Stains, Solvents and Sealants

Donate unused portions (see Resources section below) or save unused portions for your next job.

Plastic and Vinyl

Minimize waste of vinyl siding, flooring, and countertop materials by ordering only quantity needed.

Recycling is a system of collecting, sorting, and processing discarded materials for use as raw materials in the manufacture of new products. If construction materials cannot be reduced or reused, then they should be recycled (pending local market availability). Some materials can be recycled directly into the same product. Others can be reconstituted into other usable products. Recycling is not usually economically feasible unless a facility using recycled resources is located near the material generation source.

What to Reuse and Recycle

Before collecting construction waste for reuse or recycling, identify who will accept it. This is important in designating the type of waste to separate and in making arrangements for drop-off, collection, and storage of materials. In Austin, materials that can be reused include:

• appliances and fixtures
• asphalt (for road repair)
• brush, trees, and land clearing debris (for compost and mulch)
• fixtures
• lumber and plywood
• masonry (bricks, concrete masonry units, etc.) and concrete rubble (for fill)
• roofing
• windows and doors

In Austin, materials that can be recycled include:

• carpet (usually in a renovation, check with new carpet installer)
• cardboard and paper
• metals (including copper piping, wire and flashing, aluminum siding, flashing and guttering, iron and steel banding from bundles, nails and fasteners, galvanized flashing and roofing, rebar, and aluminum beverage cans)
• plastics (numbered containers, bags, and sheeting)

Materials Storage Area

Designate a specific area to facilitate separation of materials for potential reuse, recycling, and return. This area should be kept neat and clean. Bins or areas for all materials to be separated should be provided. Bins should be clearly labeled with the material to be collected in both English and Spanish in order to avoid contamination of materials. Pictures and symbols can also accompany verbiage. (For example: METAL RECYCLING ONLY and UNICAMENTE METAL PARA RECICLAR). Signage should be easy to read from a distance and from the angle of the disposer. Signage does not have to be elaborate but should be sturdy and removable for use on other bins as needed.

Bins should suit the site: craneable for multi-story projects, small and mobile for quick moving or hard-to-get-at projects, or sectioned with dividers for smaller quantity projects. They should be monitored periodically for contamination so that the problem can be more readily corrected and preventa4ive`measures implemented. The area should be in a location out of the way of construction traffic but provide adequate space for pick-up and delivery and convenience to workers. Protection from rain and pilfering may be required.
