DDRS will benefit the environment
It is not just about convenience though. During our Digital Deposit Return Scheme (DDRS) pilot in North Wales, we used data from a report published by the Irish Waste Management Association to compare carbon emissions associated with conventional DRS to those likely to result from a kerbside-based, DDRS.
As a result, it was estimated that in Wales alone, the net benefit in terms of carbon emissions derived from adopting kerbside DRS would be approximately 13,000tCO2e per annum (equivalent to burning 6,500t of coal each year).
This net reduction in carbon emissions from kerbside DRS is predominantly achieved through:
- No need for households to make individual trips to collection points (estimated at 8,000 tCO2e)
- No additional infrastructure required for reverse vending machine manufacture, system setup and installation (estimated at 4,000 tCO2e)
- No additional transport to take collected material to Material Recycling Facilities (estimated at 1,000 tCO2e)
If we extrapolate this net reduction of carbon emissions over the next 29 years – to the Net Zero target date of 2050 – then the introduction of a kerbside DRS could save up to 377,000 tCO2e.
