A new United Nations Report has recognised the importance of the novel Accelerated Carbonation Technology developed by Carbon8 Aggregates in tackling climate change, as well as supporting the waste hierarchy and recognising the environmental challenge of disposing of waste to landfill. The Carbon8 process is acknowledged as making “a demonstrable contribution to the developing European circular economy”.
The United Nations has published the sixth Global Environment Outlook (GEO-6) Assessment for the pan-European region. The UN Report is of great scientific and political importance, as it highlights the state and trends of the environment and provides an objective evaluation and analysis of the pan-European environment, designed to support environmental decision-making.
The Report addresses the mineralisation of carbon dioxide in solid waste to produce products that can be used in construction, stating:
“The management of CO2 emissions by carbon capture and utilisation (CCU) is a potentially important future part of a balanced strategy for reducing greenhouse gases emissions. CCU-related products and processes will become more cost effective and numerous and will utilise significant quantities of carbon.
One currently available CCU process involves the mineralisation of CO2 in solid waste to produce products that can be used in construction. The technology is a managed version of ‘natural carbonation’ whereby CO2 gas is converted to calcium carbonate (limestone). The carbonate-reaction is managed carefully and can be used to manufacture a substitute for aggregates made from virgin stone. Developed at the University of Greenwich the process is being applied in the UK. Carbonated manufactured aggregates are being made from air pollution control residues. The aggregates, which have a structure similar to natural limestone meet European ‘end of waste’ regulations and materials performance standards, and make a demonstrable contribution to the developing European circular economy.”
The UN Report goes on to recognise that:
“Waste volumes continue to grow. Disposal of waste in landfills is the major environmental challenge in several parts of the region, despite progress with recycling in many countries.”
“The waste hierarchy is widely accepted as a guiding framework to increase economic value from resource use and to reduce waste. Closing resource-use loops through the promotion of circular economy principles offers further pathways to minimise waste and maximise resource use”.
Carbon8 are of course delighted to be referenced in such a high profile and scientifically credible report. The business is founded on scientific rigour and is a world first developer of carbon negative aggregate, embodying the principles of the waste hierarchy and the circular economy.
