Step aside Newater, gold is the in thing now.<\/p>\n
I was reading this interesting article\u00a0about many (and wild) possibilities of\u00a0making sewage useful. The world’s population produces around 1.2 billion tonnes of faeces and 15 hundred billion of urine per year. Somebody discovered that there’s\u00a0similar gold content in sewage\u00a0when compared to\u00a0mining from geological ore deposits. In fact, certain cities and towns in the world produce higher amounts of gold in their sewage.<\/p>\n
According to the article, one of the main sources of gold\u00a0is human excrements. Our diet contains gold in trace amounts. And\u00a0our faeces\u00a0have significantly higher gold contents than chicken, cow or kangaroo droppings.\u00a0 Other sources of gold compounds come from\u00a0medicine ingested, abrasion of gold jewellery during washing and\u00a0industrial effluents coming from dental practices, electronics industries and jewellery manufacturers.<\/p>\n
There are also other useful substances such as other metals, vitamins, proteins, fats, carbohydrates and mineral oil in sewage waiting to be tapped upon.<\/p>\n
Well, here we have another valuable renewable resource as long as we live :)<\/p>\n","protected":false},"excerpt":{"rendered":"
