Compost Quality Improvement

Getting compost to FCO grade so it commands a price.

What it is

Poor, contaminated or immature compost has no market. We improve compost quality — feedstock purity, process control, maturity and testing — to meet Fertiliser Control Order (FCO) standards and command a real price.

Why it matters
  • Only quality, mature compost sells
  • FCO compliance unlocks the formal market and subsidy
  • Quality starts at segregation, not the plant
What quality rests on

FCO-grade compost, from the ground up

Marketable compost isn’t made at the testing stage — it is built up from clean feedstock through controlled process and full maturity to FCO-grade product.

FCO-grade productMeets Fertiliser Control Order specs
Maturity & stabilityFully cured, not raw
Process controlAeration, moisture, curing
Clean segregated feedstockQuality starts at source
