Plastic packaging waste has become a key consumer concern. In the UK, over 2.2 million tonnes of plastic packaging enter the consumer market each year. Much of this is used in the food sector because plastic packaging is cheap, light to transport, hygienic, and can be used to extend the product’s shelf-life. In the UK around 46% of plastic packaging is collected for recycling, mostly through local authority collections. However several issues with the current systems of plastics recycling persist. This POSTbrief reviews proposals to Defra and HM Treasury to improve plastics recycling in the UK .

This report outlines infrastructure concerns. Experts are concerned about public transport. They worry about the reduction of services and want clearer guidance on how to stay safe while traveling. They also note that after the outbreak people might not return to using public transport, which could have a range of negative impacts on infrastructure. Digital infrastructure is also an area of concern. Experts worry it will struggle to continue to cope with increased demand. In terms of energy, experts worry about volatility in the energy market and that this could affect how much energy the UK is able to import. Finally there are general concerns about the UK's ability to monitor and maintain infrastructure. Such services might have halted or reduced. On top of that, returning workers might be less familiar with the new processes and put their health and safety at risk.
