AD feedstock tested in a day

Anaerobic digestion (AD) oper­ator and services provider Amur has unveiled what it says is the industry’s first rapid inhibition test. The simple test is based on sensitive bacteria, which react quickly when exposed to inhibition-causing toxins.

AD plants are offered new feedstocks on a regular basis, and being able to understand the value of those feedstocks is critically important. Combined with Amur’s Bullet BMP technology, the new test can report back in three days.

Nigel Lee, general manager, said: “Every AD operator knows that diet is crucial to achieving optimum gas yields. Until now, operators have had to wait up to a month for confirmation that feedstocks are safe to feed. Now, they can be reassured that material is free from inhibition in one day.”

The technology uses near infra-red spectral analysis to identify the components such as starch, sugar, or fat in a sample.

The findings are calibrated and benchmarked against known biomethane potential from a range of materials, then mathematically calculated and converted into BMP.
