Scotland's deposit return scheme (DRS) can absolutely go ahead without glass bottles included, the boss of the company set up to run it has said.David Harris, chief executive of Circularity Scotland, said, however, that if the scheme north of the border was dumped as a result of a row between Holyrood and Westminster there could be knock-on impacts on similar initiatives in the rest of the UK As many as 1.8 billion cans and plastic bottles could be returned in Scotland each year under DRS with Mr Harris insisting this is well above what is currently being achieved in terms of recycling rates.
