Packaging has become the major environmental hazards as people buy more packaged food and manufacturers coming up with more packaged food products , its for the packaging industry to come up with feasible bio degradable material so as to reduce the environmental impact of packaging .Any research or development for Eco - friendly packaging are welcome and should be popularised by the food manufacturers .
New food packaging is being developed that is made of a sugar-based polymer, which means it could be composted at home along with organic waste.
The degradable polymer is made from sugars known as lignocellulosic biomass, which come from non-food crops such as fast-growing trees and grasses, or renewable biomass from agricultural or food waste.
This compares to current bio-renewable plastics which tend to use crops such as corn or sugar beet, adding pressure to supply. In additions around 7% of worldwide oil and gas resources are consumed in plastics manufacture.
The search for greener plastics, especially for single use items such as food packaging, is spurred by environmental concerns, as well as economic and supply reasons, according to by Dr Charlotte Williams, who is leading the team or researchers at Imperial College London.
Dr Williams said: “Our key breakthrough was in finding a way of using a non-food crop to form a polymer, as there are ethical issues around using food sources in this way.”
It comes at a time when many UK grocery retailers and manufacturers have pledged to cut waste to landfill and improve their environmental credentials.
The oxygen-rich sugars in the new polymer allow it to absorb water and degrade to harmless products – meaning it can be tossed on the home compost heap and used to feed the garden.
And because the new polymer can be made from cheap materials or waste products it also stacks up economically compared to petrochemical-based plastics.
The polymer has a wide variety of potential uses, not just food and it could be in use within two to five years
