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? Blood-based plastic a green bonus – New Zealand
Posted on June 2, 2013 by DrRossH in BioPlastics, Plastic Waste NewsBlood-based plastic a green bonus – Business – NZ Herald News.
Hamilton-based Aduro Biopolymers has devised a method for making bio-plastic out of blood meal, a byproduct of the freezing works process.
Harpur said that while Novatein was more expensive than some regular plastic products, which can sell for less than $2 a kg, it solved problems for its users.
For example, strawberry farmers using the bioplastic to cover their plants wouldn’t need to spend time gathering up the material after the harvest as it’s biodegradable.
It would be nice to know what, if any, special conditions were required for biodegradation to take place. It is hard to imagine that it will biodegrade away under ambient conditions after it has served its practical life. What makes it last this practical time with no biodegradation, then all of a sudden start to biodegrade away?
