COMPOSTING: TRANSFORMING ORGANIC WASTE INTO SOIL FERTILITY

This week we are celebrating International Compost Awareness Week (ICAW), an international initiative that highlights composting as a key tool to improve soil health, reduce waste and move towards more sustainable agriculture.

At Defeder, this commitment is part of our everyday work. At our Albelda plant, we focus on the valorisation of organic materials of livestock origin, transforming them through controlled composting processes into fertiliser products with high agronomic value.

Among them are OSCAGA, produced from poultry manure, and OSCATER, made from ruminant manure. Both products reflect the same philosophy: turning organic by-products into useful resources for the field.

Composting: transforming organic matter into fertility

Composting is a natural process, but it requires technical control. Through the action of microorganisms, organic matter is transformed into a stable, sanitised and nutrient-rich product.

During the process, parameters such as moisture, aeration and temperature are controlled to promote proper decomposition and maturation of the material. The result is a compost capable of providing organic matter, improving soil structure and supporting biological activity.

Agronomic value of compost

Compost is much more than a fertiliser. Its application helps to:

  • Improve soil structure and fertility.
  • Increase water retention capacity.
  • Provide nutrients gradually.
  • Promote microbial life in the soil.
  • Strengthen crop resilience.

In an increasingly demanding agricultural context, with soils affected by organic matter loss, droughts and a growing need for efficiency, compost becomes a strategic solution.

Defeder and the circular economy

At Defeder, we believe in agriculture that makes better use of available resources. That is why we promote a model based on the circular economy, giving organic materials a second life and returning them to the soil in the form of fertility.

The Albelda plant is an example of this commitment: transforming livestock-derived resources into organic fertilisers that help care for the soil, improve crops and reduce environmental impact.

Because composting is not just recycling.
Composting means regenerating, nourishing the soil and building more sustainable agriculture.
