WTV: Decarbonizing Tire Manufacturing

We previously funded diverse Waste-to-Value (WTV) projects from resource recovery to conversion of hard-to-recycle, calorie-containing waste plastics (Israel), mixed municipal solid waste (UK), and presently intend to finance recovery of fossil-carbon materials like end-of-life tires, with a case study described below.

Using a “slow” pyrolysis system with advantages for biogenic wastes, mainly for biochar, we earlier funded small-scale projects in cooperation with Carbon Drawdown Solutions, based in Hawaii. Proven feedstocks included woody biomass, livestock and agriculture wastes (horse bedding, poultry litter, etc.), water waste treatment sludges, and empty fruit baskets from palm oil production (Indonesia).

Solving the Problem of Accumulating End-of-life Tires

Case Study of processing end-of-life tires, mainly stockpiled and buried in the US (called “monofils”), via a series of “turnkey” projects that convert old tires into the raw materials of new tires with radically fewer carbon emissions.  This next generation solution generates valuable bonus co-products (beyond carbon black and steel) using breakthrough technology.

A world-class lead engineering firm has prepared from the start to rapidly replicate across multiple sites. Construction of each facility takes approximately 2 years (the first one slightly longer), with individual projects using “cloned engineering” for rapid and consistent deployment across all sites, with the initial projects based in North America.
