AD Plant Laburnum House,

Lincolnshire, UK


AD Plant located in vegetable growing area

Lincolnshire is a vegetable growing region. Significant amounts of sorted potatoes, bean straw and other vegetable processing waste accrue. So far waste potatoes were being stored at the fields, rotting uncontrolledly and spread when possible.

In the region’s grain farming sector, one of the main problem weeds is “black grass”. It can hardly be controlled chemically anymore. Additional crop rotation only can solve that problem. The AD Plant allows utilization of agricultural by-products and makes the diversification of the grain centred crop rotation by grass-clover and maize possible.


Profitable soil health improvement

  • Processing of agricultural by-products
  • Control of weed growth
  • Improving crop rotation
  • Reducing fertilizer costs
  • Control of disease and parasites



Problematic feedstock digested successfully, harvest losses compensated

A wide variety of feedstock is used in the plant, like cattle manure, pig slurry, whole plant silage, chicken manure, vegetable waste, bean straw, grain straw, potatoes from a sorting company, grass silage and small quantities of maize silage.

If black grass cannot be controlled chemically anymore, the weed infested grain is harvested as whole plant silage and thus the crop can still be used. High temperatures in the Batch-Hydrolysis destroy the seeds efficiently. That way the black grass (and other troublesome weeds’) reproduction cycle is interrupted.

With the Batch-Hydrolysis the digestion is process is effective even when feedstock is changed frequently. High amounts of unshredded potatoes are no problem for the Hydrolysis´ biology.

Soil, stones, grit and other impurities settle at the bottom of the hydrolysis tank and can be cleared away when needed.


Digestate drying secures RHI (Renewable Heat Incentive)

Digestate is dried in a system integrated dryer. It can be easily stacked, stored and spread out on the fields with little or no odour and reduced risk of nutrient leaching into watercourses. Due to this holistic concept and the usage of produced heat, the AD plant is entitled to RHI (Renewable Heat.Incentive).
