A café operator who set out to find an alternative to single-use coffee cups has helped to develop a new re-use system that claims to be the most simple and cost-effective to date.

Alasdair Hood and his team have raised £350,000 from angel investors to launch Delete Cups. The system has already been successfully trialled in the two pop-up cafes he runs in Braintree Village, Essex - Roo and FryBaby - and the company is in talks with other potential users in the UK and Europe.
