With the growing price of crude oil and concerns over the safety of everyday products it is no surprise that new alternatives are being explored in the world of plastics. Plastics are petroleum based and are linked to heavy metals and softeners known as phthalates which is cause for concern when it is being used for everything from food containers to baby toys. Plastics are also non-renewable and some are not recyclable leading to greater amounts of trash that remain in a landfill forever. When burned, plastics release toxic fumes into the atmosphere. A growing alternative to petroleum based plastics is a bio-plastic called Arboform.
