Where The Magic Happens

Explore our innovative composting facilities dedicated to creating sustainable soil solutions for a healthier planet.

Our Decentralized
Composting Network

We operate multiple strategically located composting sites to maximize waste diversion and soil restoration. Our facilities are designed for regional efficiency and environmental sustainability. We believe using food to grow more food is the highest end use of organic waste.

A Regional Model in Sustainability

Our newest and largest facility, built in partnership with the Town of Manchester-by-the-sea, MA. This building manages the primary, and smelliest, stages of composting in an enclosed space. The building controls moisture, air flow, leachate, vectors and odors.

In 2024 this facility replaced our site on School Street in Manchester, where we operated since 2017.

Effiticient Decompostion

Our recipe of food scraps (the nitrogen source) and leaves (the carbon source) is designed to foster an environment ideal for decomposition, and a rich, nutrient balanced finished compost.

Each of the windrows in the aerial image is the compost at a different stage of finishing. It takes approximately six months for the food scraps to move through this system and turn into finished compost.

Sustainable Waste Management Facility

This front runner site operates with minimal utilities. It utilizes an excavator to turn windrows.

Sustainable Waste Management Facility

Our southern site specializes in innovative composting techniques and research. It develops new methods for organic waste transformation.

How We Transform Waste into Compost

Our composting process involves carefully managed decomposition stages that convert food scraps into high-quality organic soil amendments. The compost is mixed, turned, monitored for the correct internal temperature, screened, and tested. We use scientific methods to ensure maximum nutrient retention.

Measuring Our Positive Environmental Contribution

Each ton of diverted organic waste prevents greenhouse gas emissions and creates valuable soil resources. Our facilities play a crucial role in local ecosystem restoration.
