Converting organic waste in the Ecodigster

WHY CONVERTING ORGANIC WASTE IN THE ECODIGESTER (TO ANIMAL FEED) IS BETTER THAN FERMENTATION (ANAEROBIC DIGESTION)

We list the points for you.

Higher value in the European waste hierarchy

The European waste hierarchy is a policy tool that provides guidelines for sustainable waste management. The order of preference is:

Prevention
Reuse
Recycling (including valorisation as animal feed)
Energy recovery (such as digestion or combustion)
Dump

Environmental gain

Fermentation of organic waste produces biogas (methane + CO₂), which can be used for power generation. This is useful, but:

Some of the organic material is lost as CO₂ (or worse: methane if there is leakage).
Residual streams remain (digestate) that need to be processed.

Conversion to products such as animal feed via microbial conversion.

Keeps more nutrients in the cycle.
Replaces production of new livestock feed (soya, grain), which takes a lot of land, water and energy.
Reduces greenhouse gas emissions from agriculture and imports.

This leads to improved carbon efficiency and recycling.

Cost savings

Conversion to high-value products can be cheaper and more cost-effective than fermentation:

Lower processing costs: Less digestate, less post-treatment.
Potential yield: The final product (e.g. protein-rich animal feed) has market value.
Less dependence on subsidies than for biogas plants.

You also avoid external feed costs, and reduce transport costs if conversion is done locally.

Conclusion

By converting organic waste into useful products such as animal feed:

Elevate position in European waste hierarchy
Reduce your environmental impact
Increase your economic efficiency

In short, it is a smarter, more sustainable and circular choice than fermentation.
