Farmers give up using municipal compost due to high plastic content.

Our UK team has recently finished sampling agricultural fields for plastics large and small as part of the MINAGRIS project. During this time, it has become increasingly clear that we have a compost problem.
Municipal compost is made with our kitchen countertop and garden green waste collections. When it first arrived at scale as an option for farmers to apply this valuable source of organic matter to their fields and boost their soil carbon, it seemed like a win-win. It had the potential to bring otherwise wasted nutrients back into the food system, saving them from stinking out our bins before ending up in landfill or an incinerator. This was a bold shift towards a more circular economy, which had the potential to be great for soils and farm profitability.
The problem is the high plastic content. Farmers and growers initially eager to make use of this black gold to improve their soil health quickly realised that the plastic content of municipal compost was so high that they were no longer happy putting it on their land. This came up repeatedly in our farmer interviews and whilst we were sampling. Our initial enquiries indicate that this seems to be a widespread understanding within the farming and market gardening communities, not just in the UK but Europe-wide.

MINAGRIS Featured in Swiss Independent Newspaper 'WOZ'
"Snow does not often fall on the Ross Ice Shelf in Antarctica. But when it snows, it snows plastics. Together with the flakes, tiny microplastics fall out of the clouds - 4000 kilometers from civilization. It's a gift from the wind".
Independent swiss newspaper WOZ has visited Minagris partners at the University of Bern and FiBL. They have written an illustrative piece on the work of Minagris and microplastics situation globally. Click here for the original German language version, or here for an English tanslation.
