Large amounts of sugar are excreted on a daily basis by type-two diabetic patients especially amongst the upper end of our aging population. As a result of this diabetic patients toilets often have unusual scale build up in the basin due and rapid mould growths as the sugar put into the system acts as nutrients for mould and bacteria growth. Is it plausible to suggest that we start utilizing our water purification systems in order to harvest the biological resources that our elderly already process in abundance?
