Urban waste wood carbon storage initiatives are more cost-effective and provide multiple community benefits.

Cities and companies across North America are revolutionizing waste wood carbon storage through innovative programs that convert urban tree waste into durable products, effectively sequestering carbon for decades. These initiatives are transforming municipal waste management while addressing climate change through practical, scalable solutions.

The City of Ann Arbor, Michigan recently partnered with Urban Ashes® to launch the Circular UrbanWood Triconomy (CUT Model), establishing a comprehensive

system. This program exemplifies how municipalities can transform their urban forestry waste into valuable resources while maintaining carbon sequestration benefits.

The environmental impact of urban wood waste is substantial. The United States currently discards an estimated 46 million metric tons of potential urban lumber annually, representing approximately 7 billion board feet of quality lumber – equivalent to 16 Empire State Buildings in volume. This waste results in lost

sequestration of about 5.6 million tons and generates 20.55 million tons of CO2 emissions.

Several international programs offer successful models for waste wood carbon storage. In Sweden, the Wood First program mandates the use of wood products in public construction projects, creating a structured market for recycled urban wood. This initiative has resulted in an estimated 50% reduction in construction-related carbon emissions compared to traditional materials.

The Netherlands has implemented a similar program called “Hout Eerst” (Wood First), which includes a carbon banking system for urban wood products. This system tracks the carbon stored in recycled wood products throughout their lifecycle, providing carbon credits to participating organizations. The program has documented the storage of over 100,000 metric tons of carbon since its inception in 2018.

Ann Arbor’s implementation of the CUT Model demonstrates the local potential of waste wood carbon storage programs. The city anticipates sequestering between 20 and 40 metric tons of carbon, preventing the release of 73 to 147 metric tons of CO2e. These reductions equal the environmental impact of growing 1,213 to 2,425 saplings over ten years, surpassing the city’s annual tree planting program of 1,000 saplings.

Economic analyses of waste wood carbon storage programs reveal significant municipal cost savings. Traditional tree disposal methods cost cities an average of $150-200 per ton, while recycling programs can generate revenue through product sales and carbon credits. The Swedish Wood First program reports average savings of €75 per ton of processed wood waste, while creating local manufacturing jobs.

Urban Ashes has expanded its waste wood carbon storage initiatives to over 25 U.S. cities, using advanced tracking software and established industry standards. The company’s CUT Model operates on a triple bottom line framework, balancing environmental sustainability, social equity, and economic diversity while providing career opportunities for justice-impacted youth and formerly incarcerated individuals.

The magnitude of potential impact becomes clear when comparing waste wood carbon storage programs to traditional carbon capture technologies. The world’s largest direct air capture facility, Stratos, currently under construction in Texas, requires over $1 billion in investment to remove 550,000 tons of CO2 annually – less than 7% of what the urban wood industry could achieve at 40% capacity.

When considering operational costs, direct air capture facilities typically spend between $600-$1000 per ton of CO2 removed, while waste wood carbon storage programs average $50-$100 per ton, including processing and manufacturing costs. This cost differential is particularly significant given that urban wood programs provide additional benefits beyond carbon storage, including local employment, reduced landfill usage, and manufactured products that continue generating economic value.

Furthermore, while direct air capture facilities require significant energy input – estimated at 2,000 kWh per ton of CO2 captured – waste wood carbon storage programs actually reduce energy consumption by eliminating the need for waste transportation and processing.

The Department of Energy estimates that implementing comprehensive waste wood carbon storage programs in just the top 100 U.S. metropolitan areas could achieve carbon reductions equivalent to removing 3.5 million cars from the road annually at a fraction of the cost of traditional carbon capture technologies.

In Canada, the Urban Wood Network has established a nationwide system for waste wood carbon storage, connecting municipal forestry departments with local manufacturers. Their program has processed over 500,000 tons of urban wood waste since 2019, creating an estimated $25 million in economic value while maintaining carbon sequestration.
