Project: Trejuvenation

Project Summary

The aim of this program is to divert end-of-life urban trees away from the wood-chipper/landfill and toward beneficial products like lumber, furniture, musical instruments, bio-polymers, and wood charcoal/biochar (made from low-value wood that has no current market; biochar is a powerful soil amendment for enhanced microbial growth and nutrient runoff prevention among other things). We will fill in gaps in the existing urban wood industry and our intention is to increase the amount of urban wood diverted from the wood chipper and landfill.


Trejuvenation sites do not have the “tipping” fees that landfills charge somewhat offsetting the greater expense of transporting larger logs, and we can even pay them for the logs in some cases. We will also augment the local capacity to kiln-dry logs, something that is sorely needed if this wood is to reach its full potential in terms of market value. Finally, Trejuvenation will enhance the existing urban wood network so they can more effectively collaborate, fulfill larger commercial orders, create value-added products like biochar, and market their products to a wider audience.

BENEFITS of recycling trees

Fewer members of our urban forest being chipped or burned; consideration is first given to the best use for each log

Human benefits: Job training and education in an industry fit for a 21st-century circular economy

Improving utilization of valuable resources (e.g. avoiding waste), and honoring our gentle green giants by giving them a second life beautiful life
