Answer 1

(c) The bio-degradable plastics will add to the already piling up municipal garbage. The immediate benefits of recovery and recycle of normal plastics is also lost if bio-degradable plastics are introduced. As of now, compared to normal plastic, the biodegradable plastics are expensive and the technology for manufacture is not easily available. It may be possible to treat bio-degradable plastics in countries where solid waste management systems are working satisfactorily and extensively.
