Given that Sri Lanka is a developing country, its citizens need to look at waste management without being influenced by the cost factor. About four years ago, biodegradable bags were introduced into the country. However, cost factor become a major problem when people had to buy them. The citizens always look at the short-term usage as opposed to the environmental benefits of such bag. This article looks at the benefits of biodegradable products and why Sri Lanka people should be aware of them.
Manufacture and use of biodegradable consumer products results in far less pollution. Since the products can decompose into non-toxic components, they are unlikely to cause off gassing that will pollute the air or dangerous chemical leachate capable of poisoning water. Biodegradable plastic products produce much less greenhouse gases when compared to petroleum-based plastic products.
Oil is saved when polylactic acid biodegradable products are manufactured. The processes applied in the production of biodegradable plastics consume much less energy than is needed to make petroleum-based plastics. This makes biodegradable plastics a rather energy-efficient choice. Biodegradable products are manufactured using renewable sources such as sugarcane, potato and corn starch rather than oil. A lot of oil is used in Sri Lanka in the manufacture of plastic packaging. By employing biodegradable products, significant portions of this oil use can be eliminated.
Composting biodegradable plastic products together with traditional biodegradable paper products, food, agricultural and yard wastes can turn the trash into a rich humid material. This can in turn improve nutrient and water retention, while helping the growth of healthier plants with no need for pesticides and chemical fertilizers. Currently, the only way to compost biodegradable plastics is through commercial composting facilities capable of maintaining high compositing temperatures. This is unlike the case of textile items and paper that can be composted in backyard compost bins. The good news is that the number of such composting facilities is increasing in Sri Lanka. Municipalities across the country are regularly revising their composting and recycling goals with the aim of reducing the amount of waste being disposed in costly landfills. Also, industry developments towards making materials that easily break down are on course. These factors will assist in increasing the environmental benefits of biodegradable products.
Reduction in Plastic Pollution
Plastic pollution is now a major phenomenon not just in Sri Lanka but across the world. The harmful chemicals that are found in plastics are present in the tissues and bloodstreams of almost every individual in the world. Plastic is not bio-degradable; it just breaks down into tiny particles after which its toxic chemicals are ingested by the wildlife that humans have consumed. Effects on human health are gradually being felt while they become controversial day by day. With the advent of biodegradable products in Sri Lanka, plastic pollution can be dealt with. These products do not pose any danger to the environment, and play a role in eliminating plastic pollution.
Sri Lanka recently launched a project aimed at promoting organic waste composting. Anyone who gets a Sri Lankan Visas to visit the country can benefit from the initiative. This is because promoting biodegradable products will help restore the environment.
