Wood Recycling: Lumber, Pallets, and Treated Wood
Reuse clean wood first, then take dry, untreated lumber to a wood or C&D recycler that accepts it. Painted, stained, pressure-treated, glued, and composite wood needs a different local route and should not go in mulch, compost, or a blue recycling bin.
8 materials covered
Is wood recyclable?
Yes, but not in your curbside recycling bin. A wood recycler, C&D facility, or yard-waste site turns clean, untreated wood such as lumber scraps, pallets, and branches into mulch, animal bedding, particleboard, or fuel. Painted, stained, pressure-treated, and glued products such as OSB and MDF need a separate route, and wood with lead paint or asbestos needs special handling.
Most wood that households throw away still ends up in landfills. EPA's latest figures, for 2018, count 18.1 million tons of wood in municipal solid waste. Americans recycled about 3.1 million tons, or 17.1%, burned 2.8 million tons for energy, and sent 12.2 million tons to landfills. EPA counts construction and demolition wood separately, and that wood has its own recyclers.
Hardwood Flooring
Solid hardwood and engineered wood flooring from residential and commercial installs (oak, maple, cherry, walnut, and similar species). Highest value is reuse and refinishing; grinding is a last resort for clean wood that cannot be reinstalled.

Plywood & OSB
Engineered wood panels (plywood, oriented strand board, particleboard, MDF) from construction, furniture, and manufacturing. Industrial adhesives put them in a different end-of-life path than untreated dimensional lumber.
Learn how to recycle Plywood & OSB
Wood Pallets
Wooden shipping pallets from freight and logistics. Hierarchy is reuse and repair, then remanufacture, then chip for mulch, bedding, or biomass. EPA's 2018 MSW wood recycling (3.1 million tons, 17.1%) is largely pallet-driven packaging wood.

Untreated Scrap Wood
Clean dimensional lumber offcuts and untreated solid-wood scraps from construction and woodworking. Best candidate among wood wastes for grinding into mulch, animal bedding, biomass fuel, or engineered-panel fiber when truly free of preservatives and finishes.
Learn how to recycle Untreated Scrap Wood
Engineered Wood Products
Structural engineered lumber: laminated veneer lumber (LVL), glue-laminated timber (glulam), I-joists, structural composite lumber, and cross-laminated timber. High reuse value when sound; limited clean-wood recycling because of adhesives.
Learn how to recycle Engineered Wood Products
Wood Chips & Sawdust
Sawdust, shavings, and chips from sawmills, woodshops, and tree care. Valuable when the source wood is untreated and unpainted; zero tolerance for treated-lumber dust in mulch or compost.
Learn how to recycle Wood Chips & Sawdust
Bamboo Products
Bamboo flooring, furniture, utensils, and related goods made from bamboo grass. End-of-life depends on adhesives and finishes: strand-woven and laminated products behave more like engineered wood than raw plant stalks.
Learn how to recycle Bamboo Products
Wine Corks
Stoppers from wine and spirits bottles. Natural cork comes from the bark of the cork oak, which regrows after harvest. Synthetic corks are plastic.

Wood recycling overview
In 2018, EPA counted about 18.1 million tons of wood in US municipal solid waste (6.2% of MSW), of which 3.1 million tons (17.1%) were recycled and 2.84 million tons combusted with energy recovery; 12.15 million tons were landfilled. EPA notes wood packaging such as pallets makes up most recycled wood, and recycling usually means chipping for mulch or bedding, not burning for fuel. Construction and demolition is a separate stream: about 40.8 million tons of C&D wood products were generated in 2018, with landfills taking 29.6 million tons and 11.2 million tons going to next uses (about 7.5M fuel, 2.5M compost/mulch, 1.2M manufactured products). Clean, untreated, unpainted wood is what mulch and many biomass markets want. Pressure-treated (CCA legacy, ACQ, copper azole), creosote, pentachlorophenol, and painted wood belong in authorized landfill or C&D disposal, never in the fireplace, backyard burn pile, or landscape mulch. Reuse via architectural salvage and Habitat for Humanity ReStores beats grinding when boards are still usable.
Common items
- • Solid hardwood flooring (oak, maple, cherry) for salvage or C&D
- • Clean dimensional lumber and construction offcuts (untreated only)
- • Wooden shipping pallets (reuse/repair first, then pallet recyclers)
- • Plywood, OSB, particleboard, and MDF panels (reuse or C&D, not mulch)
- • Engineered beams: LVL, glulam, I-joists (reuse or C&D/biomass)
- • Clean wood chips and sawdust from untreated lumber
- • Bamboo flooring and furniture (product-dependent; often not compostable)
- • Fence posts and deck boards (check for pressure treatment)
- • Wooden crates and clean shipping lumber
- • Tree branches and clean brush (often yard-waste programs, not treated lumber)
Before drop-off
- 1. Remove nails, screws, and metal hardware when practical; facilities magnet-sort but dirty loads get rejected
- 2. Separate pressure-treated, creosote, and painted wood from clean untreated stock
- 3. Never chip treated wood into landscape mulch or burn it in a fireplace or fire pit
- 4. Donate reusable flooring and lumber to Habitat ReStore or architectural salvage when accepted
- 5. For pallets, read the ISPM-15 stamp: HT is heat treatment; MB is methyl bromide fumigation
- 6. Return blue CHEP and red PECO rental pallets; they are not free scrap
- 7. Keep plywood, OSB, MDF, and engineered beams out of clean-wood mulch piles
Environmental benefits
- • EPA 2018 MSW wood: 3.1 million tons recycled (17.1% of 18.1M tons generated)
- • EPA 2018 C&D wood: 11.2 million tons to next use of 40.8M generated; 29.6M still landfilled
- • Clean untreated wood can become landscaping mulch, compost feedstock, biomass fuel, or panel fiber
- • Reuse and salvage keep carbon stored in lumber longer than grinding or landfilling
- • Keeping treated and painted wood out of mulch protects soil and avoids toxic smoke if burned
Practical and economic benefits
- • Usable reclaimed lumber and flooring often sell at a premium versus commodity new stock; prices vary widely by species and grade
- • Pallet recyclers buy or pick up repairable pallets; broken stock still has chip value
- • Habitat ReStores and salvage yards take reusable flooring and lumber when they accept them
- • EPA Recycling Economic Information (REI) reports about 1.17 jobs per 1,000 tons recycled as a multi-material national average (not wood-only)
- • Clean wood loads cost less to tip than mixed or contaminated C&D at many facilities
Local rules vary
Urban areas often have architectural salvage shops and Habitat ReStores; acceptance lists differ by store, so call first. Some municipalities take clean brush or untreated wood in yard-waste programs but reject deck boards and painted lumber. C&D processors and pallet recyclers are the main industrial paths. Treated-wood rules are set locally even when federal hazardous-waste listing does not apply to household treated wood.

Complete Wood Recycling Guide
Sustainable Resource
Wood is beneficial to recycle because it stores carbon and can be reused in many forms, from mulch to feedstock for biomass energy.
- • Untreated: Ideally recycled into mulch or compost
- • Treated/Painted: Often requires special handling or disposal
- • Pallets: Can be repaired, reused, or ground into chips
Environmental Impact
Recycling wood waste prevents it from taking up landfill space and reduces the need to cut down new trees for products like mulch.
Wood Recycling FAQ
Can treated wood be recycled?
Not in a clean-wood mulch or compost stream. Pressure-treated, painted, and stained wood needs a local C&D, transfer-station, or disposal route, and the accepted option varies by facility. Clean, untreated wood is the material most likely to be reused, chipped, or recycled.
What happens to recycled wood?
Clean wood gets reused, chipped into mulch, processed into animal bedding or biomass fuel, or sold to particleboard makers. The wood's condition and the processor decide which, so not every drop-off turns it into mulch.
Can I put wood in the recycling bin?
No. Curbside recycling programs do not take lumber, pallets, flooring, plywood, or branches. Take lumber to a C&D facility or salvage yard, pallets to a pallet recycler, and branches to yard waste.
Can wood go in the yard-waste bin?
Branches, brush, and clean chips go in yard waste. Lumber, deck boards, pallets, and treated wood do not. Check the local size and material list before using a green cart or brush drop-off.
Is plywood recyclable?
Often, but not in your curbside bin. C&D facilities recycle plywood with other demolition wood into fuel, particleboard, or mulch. Glued panels such as OSB and MDF, and painted or treated sheets, often need a separate route. Reuse sound sheets first, then call a C&D facility and ask whether it takes plywood, OSB, MDF, or particleboard.
