The household waste is called garbage. Some of the garbage is biodegradable and some are non biodegradable. Garbage causes pollution of air, water and soil. So it should be disposed properly. Some of the methods of garbage disposal are :-i) Land fills. ii) Recycling . iii) Production of biogas and manure. iv) Preparation of compost. v) Incineration
Heat-induced pressing during the manufacturing process gives structural strength to the cutlery. Additionally, the inter-fibre bonding makes the products water and oil resistant. It is a completely natural process and involves no binders, additives, coatings or chemical residues, resulting in a nontoxic, harmless and healthy alternative to plastic.

May 12, 2021·2.1.1. Fermentation . PHA is a bio-based polymer synthesized by various bacterial cells such as Cupriavidus necator and Bacillus sp. under specific growth conditions such as excess carbon sources and limited nitrogen sources [14,15].PHAs were first discovered by Lemoigne in 1925 and are a family of naturally occurring biopolyester synthesized …
Apr 06, 2018·Poly(e thene): is used to make plastics bags, buckets, bottles. It is a flexible, easily moulded, waterproof, chemical proof, and a low density plastic. Poly(e thene) is chemically inert due to the strong C-C and C-H bonds and non-polar nature of the bonds and therefore is non-biodegradable. The polymer chains consist of strong covalent bonds.

In one of the methods of disposal B, material A is burned at a very high temperature of about 1000°C in a structure called C. During this process, the organic matter present is removed as D and E whereas F is left behind (which can be dumped in a landfill site).
(a) DDT is non-biodegradable and hence found in Largest concentration in tertiary consumers. (b) DDT is non-biodegradable and found in Largest concentration in producers. (c) Largest concentration of DDT is found in secondary consumers on which eagle feeds. (d) DDT is a strong chemical which makes the eggs fragile. Answer:
These detergents are known as biodegradable as they are destroyed by the bacteria. Sodium alkyl benzene sulphonate is an example of biodegradable. Non-biodegradable detergents are defined as the type of detergent that has a branched hydrocarbon chain. These are known as non-biodegradable because bacteria cannot act on them.
Jan 10, 2022·(D) they are made of non-biodegradable materials. Explanation: Disposable plastic plates should not be used because they are made of non- biodegradable materials. Under certain conditions, the non-biodegradable substances can persist for longer time and can also harm the various components of ecosystem. Question 15.
Jan 15, 2005·At present, PEGs of M n up to 20,000 Da are known to be biodegradable (Kawai, 1995, 2002). The biodegradation of higher M n PEGs may be more difficult as the degradation mechanisms involved–whether aerobic or anaerobic–require that at least one terminal hydroxyl group must be free.
