Deletion of Zero waste agriculture

Comment: Intensive farming has a big problem with waste – I was reading about NI's "https://www.theguardian.com/environment/2021/jun/23/poo-overload-northern-ireland-could-be-forced-to-export-a-third-of-its-animal-waste poo overload" just a few days ago.  The page in question is about an obvious response – a more traditional style of agriculture in which by-products are recycled as manure and the like so that nothing is wasted.  It's easy to find books such as ''Zero Waste – Management Practices for Environmental Sustainability'' and ''Sustainable Resource Recovery and Zero Waste Approaches'' which naturally include agriculture in their scope.  Our policy  therefore applies as it's our policy not to waste such promising material – see
