Poultry litter composting: from a 150-day cycle to 30

Result of the poultry pilot with live inoculant, with no carbon added at this stage.

What was done

Pilot of industrial composting of poultry litter with a live inoculant: FILABIOSA at close to 0.9 litres per tonne of manure, when building the pile and at every turning. At this stage no functional carbon was added, to measure the effect of the inoculant alone.

What was measured

The monitoring is mandatory and always the same: internal temperature at two points per pile, moisture, odour on a scale of 1 to 5, the date of each turning, and laboratory analysis on day 0 and on day 30.

  • Composting cycle: from 150 days to 30.
  • Odour: less ammonia smell throughout the process.
  • Nitrogen: better retention in the finished material.

Why the pile responds this way

Badly made compost loses nitrogen, smells and takes months. With directed inoculation the fermentation starts fast, the pile builds temperature in a controlled way, nitrogen is retained and the odour drops, which is what matters to an industry with neighbours around it. The lactic acid bacteria colonise fast, lower the local pH and speed up the decomposition of the organic matter.

How the pile is built

Inoculation goes in when building the pile and at every turning, with the inoculant diluted in water. For accelerated feedlot composting we use a closed five-component pack: three solids, silicate, rock dust and functional carbon, and two liquids, molasses and FILABIOSA. The difference in colour, texture and odour between the incoming material and the finished product is the photo that sells this work best.

What it means for the farm

Raw poultry litter is an environmental liability. Well processed, it becomes the base input of our soil amendment: CARBOterra is made with composted poultry litter, functional carbon and inoculant. We solve a cost for the farm and we buy its residue. The same principle, in its farm version, serves the grower who composts their own manure: FILABIOSA at 0.1% plus functional carbon at 1%, with a cycle that drops from 90 to 150 days to 30 to 45.

An honest note

The industrial project is at the approved pilot stage, not in continuous operation. The figures are those of the pilot; those at scale will be published when they exist.
