Zero Waste Scotland currently has a fund open that churches registered as an Eco-Congregation may be interested in. The essence of this fund is to look to change householders behaviours to increase recycling or reduce food waste from the home through delivering innovative communication engagements.
The following website has some information on this fund:
The fund is open until Friday 13 September 2013 and offers grants for up to £30K. This is likely to be too tight a deadline, but its possible that other funding for similar projects may be available in the future.
