Casella transforms organic waste streams (over 400,000 tons annually) including food scraps, wood ash, paper mill by-products and biosolids into nutrient rich earthlife® soil amendments and renewable energy.
We believe that innovation, skill, and a measure of creative thinking are an important part of managing a broad range of solid waste challenges. That's why we are constantly evaluating new technologies and services to manage society's residual waste streams including sludge, paper fiber, ash and food processing byproducts.
Organics recycling is nature's original form of recycling, and the practice is as old as life on earth.
Within the municipal solid waste (MSW) stream, organics include food scraps, yard debris, and soiled paper. Beyond the MSW stream, the category includes things like wastewater treatment biosolids, food manufacturing by-products, animal manures, paper mill residues, wood ash, and other mineral residuals. We work to recycle these materials and return their value to the soil through composting, anaerobic digestion, land application, and other methods.
