Our Mission
To divert usable lumber from the waste stream, extend the lifecycle of forest resources, and provide the construction and design industries with high-quality reclaimed materials that reduce environmental impact without compromising on performance or aesthetics.
Founded in Los Angeles in 2009, GreenBoard Reclaimed was born from a straightforward observation: the region's construction boom was demolishing thousands of buildings that contained irreplaceable old-growth timber — Douglas Fir, heart pine, chestnut, and longleaf pine that could never be harvested again — and sending most of it straight to landfill. We exist to stop that waste and to prove that the most sustainable building material is the one already built.
Why Sustainability Matters in Lumber
The construction industry is responsible for approximately 40% of global CO2 emissions and generates more than 600 million tons of waste annually in the United States alone. Lumber, while a renewable resource, still carries a significant environmental cost when harvested new: deforestation, habitat destruction, transportation emissions, and mill energy consumption all contribute to an unsustainable cycle.
Reclaiming lumber disrupts this cycle at its most impactful point. When we rescue a Douglas Fir beam from a demolished warehouse or salvage heart pine flooring from a century-old factory, we're not just saving wood — we're preserving the decades of carbon that tree sequestered during its growth, avoiding the emissions that would come from harvesting and processing a new tree, and keeping valuable material out of landfills where it would decompose and release methane.
California alone generates an estimated 8.8 million tons of construction and demolition debris each year, with wood comprising roughly 30% of that total. The Los Angeles Basin, one of the most active construction markets in North America, accounts for a disproportionate share. GreenBoard Reclaimed operates at the center of that activity, intercepting material before it reaches the waste stream and reintroducing it as premium building product.
Carbon Neutral Processing
Our de-nailing and re-milling operations run on 100% renewable energy sourced through a community solar agreement with LADWP. Wood waste from processing is converted to biomass fuel rather than sent to landfill, closing our on-site carbon loop.
Zero-Waste Goal
We recover value from every part of the wood we process. Unusable dimensional pieces become mulch for landscape contractors, fine shavings become animal bedding, and the remainder feeds our biomass energy agreement. Our current landfill diversion rate is 97.4%.
Local Sourcing Priority
We prioritize demolition sites within 150 miles of our Commerce facility to minimize transportation emissions. In 2024, 84% of our sourced material came from the greater Los Angeles Basin, keeping supply chain emissions well below industry average.
Carbon Lifecycle Analysis
A full lifecycle analysis (LCA) compares the total carbon impact of reclaimed lumber against virgin-harvested lumber across every phase: extraction, processing, transportation, use, and end-of-life. The numbers are striking. New dimensional lumber carries a cradle-to-gate carbon footprint of approximately 80–120 kg CO2eq per cubic meter, depending on species and mill location. Reclaimed lumber processed at a facility like ours carries a cradle-to-gate figure of 12–18 kg CO2eq per cubic meter — an 85–90% reduction.
Phase-by-Phase Carbon Comparison (per 1,000 board feet)
| Lifecycle Phase | New Lumber (kg CO2eq) | Reclaimed Lumber (kg CO2eq) | Savings |
|---|---|---|---|
| Forest harvesting & site preparation | 48.2 | 0.0 | 48.2 |
| Sawmill processing & kiln drying | 31.7 | 6.4 | 25.3 |
| Transportation (mill to distributor) | 12.4 | 3.1 | 9.3 |
| Packaging & distribution | 4.8 | 1.2 | 3.6 |
| Preserved carbon sequestration (credit) | 0.0 | −22.5 | 22.5 |
| Avoided landfill methane (credit) | 0.0 | −8.9 | 8.9 |
| Total Net Carbon Impact | 97.1 | −20.7 | 117.8 |

The Carbon Sequestration Dividend
One factor frequently omitted from simple CO2-saved calculations is the carbon sequestration credit. A mature Douglas Fir that grew for 80–120 years before harvest locked an estimated 0.9–1.4 metric tons of carbon into its fiber. When that wood is reclaimed and placed back into service in a building, that carbon remains sequestered. When the same tree's wood is sent to landfill or burned as waste, the sequestered carbon re-enters the atmosphere over 5–40 years depending on decomposition conditions.
Our reclamation model therefore achieves a double benefit: it avoids the carbon cost of producing new lumber AND it extends the carbon storage life of existing timber by decades. Independent LCA researchers classify this as a “carbon banking” strategy — one of the most cost-effective carbon mitigation tools available to the construction sector.
Water Usage Comparison
Water is rarely discussed in lumber sustainability conversations, but its impact is substantial. Conventional lumber production consumes water at every stage: log pond storage, sawmill cooling, dust suppression, kiln steam generation, and surface treatment. In drought-prone California, this matters enormously.
New Lumber Water Consumption
- Log pond & storage1,200 gal / MBF
- Sawmill cooling systems2,800 gal / MBF
- Kiln drying (steam)3,400 gal / MBF
- Dust suppression600 gal / MBF
- Total~8,000 gal / MBF
Reclaimed Lumber Water Consumption
- De-nailing & cleaning180 gal / MBF
- Re-milling cooling320 gal / MBF
- Kiln re-drying (if needed)0–900 gal / MBF
- Facility sanitation40 gal / MBF
- Total~540–1,440 gal / MBF
Net result:Every thousand board feet of reclaimed lumber GreenBoard processes conserves an estimated 6,600–7,460 gallons of water compared to new lumber production — enough to supply a California household for 40–46 days. Across our 2024 throughput of 4.2 million board feet, that represents over 27 million gallons of water conserved.
Biodiversity Impact
The biodiversity consequences of timber harvesting extend far beyond the immediate cutting site. Forest fragmentation, road-building for logging access, altered hydrology, and loss of old-growth habitat structure all cascade through ecosystems for generations. Every board foot of reclaimed lumber we process represents wood that did not require a new logging operation.
Old-Growth Habitat Preserved
Much of the lumber we reclaim comes from buildings constructed before 1970 using old-growth timber — trees that were 150–400 years old at time of harvest. These trees came from forests that no longer exist. By keeping this material in circulation, we eliminate any incentive to seek ecologically equivalent replacement wood from the few remaining old-growth stands.
Spotted Owl & Marbled Murrelet Territory
Pacific Northwest Douglas Fir, a common species in our inventory, historically came from forests that now serve as critical habitat for threatened and endangered species. Our sourcing model removes market pressure from sensitive forest areas, supporting ESA-listed species recovery indirectly but meaningfully.
Watershed Protection
Logging roads and clearcuts are a leading cause of watershed sedimentation in the American West, harming salmon runs and municipal water supplies. Reduced demand for new timber translates directly into reduced road construction in sensitive watersheds. We calculate that our 2024 volume avoided the equivalent of 3.1 acres of new forest disturbance.
Urban Ecology in Los Angeles
Our facility in Commerce sits within a densely developed industrial corridor. By processing materials locally rather than shipping out-of-region, we reduce truck traffic and associated particulate emissions in communities that already bear disproportionate air quality burdens — directly benefiting urban wildlife corridors along the Los Angeles River.

The Circular Economy Model
The circular economy is a systems-level approach to production and consumption that eliminates waste by keeping materials in use at their highest value for as long as possible. In contrast to the traditional linear model (extract → manufacture → use → discard), a circular model closes the loop so that the end of one product's life becomes the beginning of another's.
Source Identification
We identify buildings scheduled for demolition or renovation and evaluate the reclamation potential of their structural lumber, flooring, and timber components before any work begins.
Selective Deconstruction
Rather than mechanical demolition, we use selective deconstruction techniques that maximize material recovery. Boards are hand-removed, stacked, and catalogued on-site, preserving structural integrity.
Processing & Grading
Materials enter our Commerce facility where they are cleaned, de-nailed, kiln-verified, graded, and inventoried. Each piece is tagged with its species, origin, and grade before entering stock.
Re-Sale & Deployment
Processed material is sold to builders, architects, designers, and DIYers who incorporate it into new structures — where it will remain in service for another 50–100+ years.
Cascade Streams
Material below our appearance or structural threshold is cascaded to lower-value uses: pallet production, compost facility mulch, or biomass energy — always at the highest viable application.
Future Reclamation
Buildings constructed with our reclaimed material today are effectively warehouses of future reclaimed lumber. We maintain origin records so the material can be identified and reclaimed again in 2075.
Why this matters:The Ellen MacArthur Foundation estimates that a circular economy approach to construction materials could reduce global CO2 emissions from the built environment by 38% by 2050. GreenBoard Reclaimed operates exactly this model — not as an aspirational goal, but as our daily operating practice in Los Angeles.
Community Partnerships
Sustainability is not only environmental — it is social. GreenBoard Reclaimed maintains active partnerships with organizations across Los Angeles to ensure that the benefits of reclaimed lumber reach communities beyond commercial construction. In 2024, we contributed over 21,000 board feet of material and 400 volunteer hours to the following partners:

Our team is trained to provide the chain-of-custody documentation that LEED auditors require.
Community Impact
We donate usable off-cuts and small-dimension lumber to local woodworking education programs, Habitat for Humanity chapters, and community workshop spaces. In 2024, we donated over 21,000 board feet of usable material to six community organizations across Los Angeles County, with a fair-market value of approximately $38,000.
Transparent Reporting
We publish annual sustainability reports detailing our material throughput, waste diversion rates, carbon offset calculations, and community contributions. Accountability is not optional when your mission is environmental stewardship. Our full 2024 report is available on request.
Continuous Improvement
We invest in research and technology to improve our reclamation rates, reduce processing waste, and find new applications for materials previously considered unusable. Our R&D team is currently piloting safe reclamation protocols for ACQ-treated lumber, which represents an estimated 15–20% of residential demolition wood currently going to landfill.
