Yes, naay Biodegradable nga mag plastic bags. Like sa kanang mga ubang department stores or mall naay naka suwat dha sa bag.
Ang question is how safe jd ni cla og how are they better for the environment?
What are biodegradable plastics? Biodegradable plastics are plastics that can be broken down by microorganisms (bacteria or fungi) into water, carbon dioxide (CO2) and some bio-material. So, can we just throw them away besides they are "biodegradable" right? That is downright an irresponsible behaviour. A biodegradable plastic bag that’s thrown into a hedge will still take years to disappear, rather than days as some people believe. Even a banana skin - when thrown away - needs 1-3 years before it is biodegraded! biodegradable plastics require specific conditions to biodegrade properly (micro-organisms, temperature, and humidity), and if not managed properly they may be worse for the environment than conventional plastics. When biodegradable plastics are put into landfill (which should always be avoided in any case) they produce harmful greenhouse gases when breaking down.
Biodegradability should therefore be regarded as an additional functionality when the application demands a cheap way to dispose of the item after it has fulfilled its job (e.g. for packaging, protect food and keep it fresh).
To conclude, it is a mistake to focus on finding ways to make products easier to throw away in the name of helping the environment. Biodegradable plastics are exciting and useful materials, but they should only be used when they have a concrete benefit for a specific product. The best way to help save the planet is to save energy and improve ways of recycling and recovering all plastics.
How long does it take for plastics to biodegrade?
