Hello, I'm Bill Callahan, founder of Marin Community Benefit Cooperative (MCBC). I'm attempting to raise $4,500 to cover the costs (and related expenses) of filing MCBC's 501c3 non-profit application, so it can begin serving the needs of Marin. More specifically, recovering solid reusable wood from our built environment and urban forest and making it available for reuse in our homes and businesses. A 501c3 non-profit status will allow MCBC to become eligible for the many state and community grants, the type of which MCBC is experienced and capable of performing.

In 2016, MCBC was certified by ZERO Waste Marin to perform the work of recovering new and used construction debris here in Marin. Unfortunately, I was unable to garner the necessary community support at the time. Nonetheless, today is a new day, as today the need couldn't be more urgent as our global temperature and sea levels are rising rapidly.

Today and every day, tons of valuable and purposeful wood (carbon) from our built environment: new construction, reconstruction, and demolition, and from our natural environment in the form of fallen trees from our yards, streets, neighborhood parks, commercial and institutional properties are treated as waste. The majority becomes a landfill cover or a fuel source to produce more energy for just a moment in time.  While these uses provide solutions for fulfilling local needs, we are sadly tossing out the baby with the bath water, so to speak, as there is significant economic capacity and potential far beyond these uses. 

On the other hand, if we recovered all of the materials showing potential and value at the source and put it all to work, we could create many new green jobs, materials, products, business opportunities, and circular dollars. We will also lay a circular foundation and its underpinnings, without which a circular community and economy cannot exist. And, imagine, as a bonus, we get to squirrel away (store) tons of greenhouse gases from all the wood we put to work instead of letting it quickly return to the atmosphere. MCBC will keep detailed records recording all the carbon collected and stored (squirreled away) in new materials and registered in MCBC's Carbon Bank. MCBC will also recover other construction materials, including metal products, for reuse, as today, most are recycled. It's important to note that although metal recycling has its merits, it requires more energy and produces more greenhouse gases. It's far better to reuse whenever we can!

If you hate waste, especially of urban trees and wood as I do, please support this effort, as the benefits are many and good for all of Marin.

Thank You
William Callahan
