The supermarket Waitrose will remove black plastic trays from meat, fish and fruit and veg ranges by end of year.
The retailer has today announced that it will stop selling packs of disposable straws from September 2018. This builds on its track-record for being the first supermarket to stop selling items containing microbeads from September 2016 and switching exclusively to paper-stem cotton buds. Plastic straws will be replaced by non-plastic alternatives.
Many headlines have been made by the pledge to eradicate avoidable plastic waste, but the plan also considers sustainable land management, nature enhancement and reducing pollution, among other things.
Making grasses more digestible promises improved feed for ruminants and better biomass for biofuel production, with economic and environmental benefits for both.
Plant biomass contains considerable calorific value but most of it makes up robust cell walls, an unappetising evolutionary advantage that helped grasses to survive foragers and prosper for more than 60 million years.
The trouble is that this robustness still makes them less digestible in the rumen of cows and sheep and difficult to process in bioenergy refineries for ethanol fuel.
