Corn Starch Biocompostables – What Are They?

Corn starch biocompostables are in essence biocompostable plastics made from renewable, biodegradable corn starch. Thankfully, plastics technology has come a long way. All traditional plastic is made from petroleum products. The production of petroleum-based plastics involves all kinds of chemicals, some of which have raised health concerns among consumers. Such plastics do not biodegrade. They are made with a non-renewable resource: petroleum. There are environmental and health concerns associated with conventional plastics.

How Are They Made?

As the name implies, they are made from corn starch. The starch is converted into a polymer, the main ingredient in materials that have a plastic-like feel. The plastics can be clear or opaque, soft or hard. A kind of acid called polylactic acid (PLA) is made from the corn starch. This is why they are sometimes called PLA plastics.

PLA plastics are molded the same way conventional plastic is. They can be molded, extruded, or shaped by heating and cooling (thermal shaping).

Ethanol Ethics

ethanol ethics, co2 emissions

Can't have your corn and eat it too Mr. President!

Ethanol ethics, quite frankly, I never saw the point of ethanol. It does, however, reduce greenhouse gas emissions by as much as 20 percent. It also reduces gas mileage, by as much as 33 percent (E10), and it also costs as much as .74 btu of fossil fuel for every 1 btu of energy, so that is only a 26 percent gain in energy produced, and that energy is fossil fuel based, so that means more greenhouse gases to produce it. Another factor to consider is that for every increase in ethanol mixtures for our gasoline, there also comes a reduction in miles per gallon, thus, more cost to us as consumers. It also is a conflict of interests, and serious conflicts for that matter. The battle for food resources comes into play, as more resources are being used to produce ethanol for energy, less can be used for human and animal food production. That conflict alone must bring ethics into the management of ethanol policies for the U.S. and what impact our policies have on the worlds food supply. Continue Reading Ethanol Ethics Here
