Managing director of this company, which imports additive for manufacturing biodegradable plastic products, stated that these additives use metal ions to enter oxygen into the polymer chains and break their molecular chains. So, polymer's decomposition time is decreased and it becomes more accessible for microorganism activity.
Eng. Arash Azmandian further highlighted that for manufacturing corn-starch bags, plastic producers should bore some costs for changing their raw materials and machineries as well as training personnel, but using this additive is a simple low cost method which requires no change in the manufacturing process.
This method is economically viable because just about 20-25 percent extra cost is born by the producer, while the costs will be boosted by 4-5 times in other methods, he added.
Producing and using environmentally friendly(biodegradable) plastic materials should be institutionalized in the society, the managing director of Behineh Saman Arian Engineering Company commented adding the governmental officials could play serious part in this due.
Manufacturing ordinary plastics such as polyethylene and polypropylene products is considered as law breaching in many countries such as United Arab Emirates and Yemen, so producers prefer producing biodegradable plastics so that they are not forced to pay some heavy penalties, Azmandian added.
Environmentally friendly (biodegradable) plastic products are currently produced in our country by using d2w additive with drop sign. This additive makes the decomposition process of plastic shorter.
