Sustainable From the Ground Up

At Eco Green Compost, sustainability isn’t an afterthought—it’s part of our DNA. Our compost is made through a closed-loop system that benefits both the environment and our family farm

Premium Compost Backed by Science, Built for Results

At Casswell’s, we don’t just talk sustainability — we engineer it.
Our compost is independently verified by MAD Consultancy, the industry specialists who analyse nutrient values, performance, and real-world viability. Their testing proves what our customers already know: our compost meets — and exceeds — industry standards. Working closely with British Garden Centres, MAD, and experts at Lincoln University, we’ve developed a product with exceptional benefits:

  • High water-holding capacity for long-lasting soil moisture
  • Nutrient-rich composition to fuel healthier, stronger growth
  • Outstanding soil-conditioning qualities that transform land naturally
  • A genuinely lower environmental footprint thanks to responsible, science-led production

This is compost built for farmers, growers, landscapers, and anyone who wants results without compromise — premium performance, proven sustainability.

Our approach not only cuts down on industrial fertilisers and chemical inputs but also gives back to the land we’ve called home for generations. We believe truly sustainable farming means working with nature rather than against it—and Eco Green Compost proves it’s possible.

Green Growing Crop

We cultivate a specialised blend of legumes, cut them for compost, and leave the roots to enrich the soil, lock in carbon, and support biodiversity.

Straw & Willow Usage

Wet or damaged straw, otherwise destined for burning, is given a second life as a crucial composting material. We also grow willow on non-productive wetlands and chip it for compost structure helping wildlife thrive while reducing waste.
