Digestate contains the Nutrient taken from the land and bioculture during the production of the feed-stocks from both food and crop feed-stocks.
Returning the Nutrient from whence it came is environmentally friendly, cost effective and makes a valued addition and contribution to the Circular Economy.
Most weed-seeds are killed in the process if the plant operates effectively, and in the case of food-waste, pasteurisation is a regulated part of the operation.
Dock seeds are highly unlikely to survive the process: https://croprotect.com/weeds/docks
One benefit of Digestate is, you know what your getting, if you don't know what the Nutrient Balance is DON'T USE IT !!!!!
Once you know the values (NPK) it can be spread (preferably injected) at the volumes required, maybe more than one application is required dependent on ambient temperature.
The Plants using food-waste should be PAS110 accredited, this allows them to apply to be part of the Biofertilizer Certification Scheme, therefore plastics and inert material should not be a problem: http://www.biofertiliser.org.uk/
Digestate offers a great alternative to chemical fertilizer, as well as having organic credentials that can contribute to the re-invigoration of bioculture in soils and cleaner water systems.
Do it right !!
Pas 100 and 110 aren’t policed properly. Samples sent in are always hand picked and then batch numbers are easily doctored. When there’s a site inspection all the paperwork will obviously be present and correct and even if there’s visible contaminant the reply is ‘it’s in the process of being cleaned’.
It’s a totally flawed system and not worth the paper it’s written on.
