Environmental Issues

  • Current global MSW generation levels are approximately 1.3 billion tonnes per year, and are expected to increase to approximately 2.2 billion tonnes per year by 2025. This represents a significant increase in per capita waste generation rates, from 1.2 to 1.42 kg per person per day.
  • The world's annual consumption of plastic, 5M tpy in the 1950s is 100M tonnes today. (WRAP)
  • Plastic waste generated annually in the UK is estimated to be nearly 5 million tonnes (WRAP)
  • Plastic destroys the ocean & wildlife & also represents a huge loss of embodied energy, even in countries with well developed waste disposal systems such as the UK
  • Plastic has been shipped to China for inappropriate disposal – now banned by China
  • A new answer is needed for safe disposal and to recover energy
  • In 2014 2.2m tonnes of plastic were used in packaging in the UK (DEFRA)
  • Only 842k tonnes were recovered, 37%, mostly milk and beverage bottles.
  • Mixed Plastic is often landfilled
  • Economically inefficient to destroy plastic through incinerators due to its high CV
  • PERN encourages exporting the problem to other countries
  • Until now no-one can valorise un-recyclable plastic cleanly and economically

What to do with waste plastics?

  • Landfill – space limited and reducing, rising cost, resource wasteful
  • Incineration – electrical efficiency limited by steam cycle & plastic reduces throughput
  • Anaerobic Digestion – limited to biodegradable polymers
  • Gasification – frequently poor quality syngas including CO2, tar and oils

A new answer is needed for safe disposal and efficient energy recovery

  • DMG produces distributed power and hydrogen from mixed waste plastic
  • DMG creating the new hydrogen economy
