Green Chemistry Principles - Renewable Feedstocks - Environmental Chemistry - Chemistry
Learn the basics about the renewable feedstocks principle of green chemistry, as a part of environmental chemistry.
Many plastic products are derived from crude oil, which is a non-renewable resource.
It takes millions of years for dead carbon-based living
organisms to be compressed by layers and layers of sediment before we get crude oil. Hence there is not an infinite supply of crude oil.
The term renewable feedstock refers to raw material derived from natural resources. The usage of renewable feedstock reduces the amount of harmful waste produced from the crude oil refinery and distillation processes.
Most printer inks are made from crude-oil derived pigments. Soy-based inks are being developed, which come from a plant and so is a renewable resource. The recycling process of paper products printed with soy-based inks is also considerably more environmentally friendly. When paper products are recycled, the ink on paper needs to be removed first which is difficult with petroleum based inks, but significantly easier to de-ink soy-based inks.
