Breaking down bioplastics myths, realities
Posted on February 8, 2019 by DrRossH in Plastic Waste NewsAsk any 10 people what bioplastics are, and the odds are that nine will get it wrong. In the past, misunderstandings and misconceptions about bioplastics have tended to color the perception of these materials in the market, and these prejudices are still evident even today. Feedstock, supply andDispelling the notion that bioplastics do not equal biodegradable plastics has proven more arduous that expected, leading the bioplastics industry to reconsider the terms used to designate these materials. Properly speaking, bioplastics refer to materials based on biomass, materials that areMany bio-based polymers occur naturally, requiring only to be extracted and slightly modified to become a bio-based plastic material. The backbone chain of the natural polymer is retained. Examples include polysaccharides, cellulose, starch, proteins and even the PHAs produced by bacteria. ThereA much-heard argument against bio-based plastics is that using arable land to grow food crops to produce plastics is wrong. Currently, the two main crops grown for this purpose are corn and sugarcane and, to a lesser extent, sugar beet and cassava. The amount of land this required at the end ofIf they’re not biodegradable, then why the push to develop bio-based plastics at al

How many people today grab a takeaway coffee cup from the local cafe to drink on the go? We don’t know, but the number must be enormous.. Most every one of the above have a plastic top that will last 100s of years. Some cafes still use plastic cups that last a similar time. Is 10 minutes of coffee worth 100s of years of trash?
These items can be seen littering our gutters and on our streets all over the place. If they were all cardboard, they would still be littered, but they would, at least, be gone in a short time.
They do not need to be made of plastic.
On the way home from the gym last week, a distance of about 1 km (1/2 mile), I counted the items of plastic litter on the curb as I walked. In that short distance I counted 63 pieces of plastic litter. Plastic drink bottles, bottle tops, candy wrappers, plastic film, polystyrene fragments etc. That seemed to be a lot to me. I guess it is a generational thing. Our parents would have been horrified to see that amount, whereas it seems to go unnoticed by our youth of today. In another 20 years how many pieces will there be on this stretch, -- 200? What will today’s youth think of that new amount then when they are older? Will their children be so readily accepting of a higher amount of litter?
