These breeds of black goats have an appetite and can digest paper, wood and presumably other similar materials even including some plastics like expanded polystyrene. I have witnessed them eating used cigarette boxes with their wrappers including the aluminum foils! A recent news item shows that they are being re-introduced in the Jerusalem hills to help reduce the low brush-wood and stop fire dangers from this.
These goats are useful and produce milk, meat and hides. In exchange for this we can let them consume our cellulose cups and similar containers and single-use items. Goat farms should be developed where the used cellulose containers are presented to the goats, after:
a) a campaign for the use of cellulose containers instead of other plastic cups etc., is launched and
b) the used cups etc., are collected by the public for subsequent distribution to the goat farms. Financial rewards for this may be introduced to encourage this work of collection, where the quantities of cups can be counted (not weighed).
No high technology is needed for this means for significant reduction in both hot and cold liquid single-use cup containers. Of course somebody will look at how the digestive system of the goats is so special that it can manage to digest paper etc., and eventually a chemical plant for it will follow. But to begin to introduce this vital and effective means for many kinds of single-use cups, the black goats are a most promising answer.
