97173
Give any two ways in which biodegradable substances would affect the environment. Answer: They may produce foul smell during decomposition process. They may produce some harmful gases such as ammonia, methane, carbon dioxide, etc., which can further-cause global warming.

Biodegradable plastic bags Biodegradable bags are made from plant-based materials like corn and wheat starch rather than petroleum. ... Plus, if biodegradable bags are sent to landfill, they break down without oxygen to produce methane, a greenhouse gas with a warming capacity 21 times more powerful than carbon dioxide.

Difference Between Biodegradable and Non-Biodegradable Substances. Biodegradable substances are those that degrades or break down naturally. Non-biodegradable substances are those that do not degrade easily. These terms itself defines the ability of the substances which are degradable or not.

Almost two thirds of landfill waste is biodegradable. This waste rots and decomposes, and produces harmful gases (CO2 and Methane) which are both greenhouse gases and contribute to global warming. Landfills also pollute the local environment, including the water and the soil.

Answer: (i) Non-biodegradable substances cannot degrade and contaminate soil and water resources . (ii) They may cause bio-magnification in the food chain and end up in humans. For example, pesticides like DDT enter the food chain, biomagnify and affect human being and other organism.

Chalk Ingredients Biodegradable or “environmentally friendly” does NOT mean that the substance can go into the local streams. The material can harm aquatic organisms by altering water quality and chemistry.

Fact: Bioplastics can be biobased and/or compostable. ... Other bioplastics are completely biodegradable/compostable, but are made with fossil materials. Whether a material can biodegrade or be accepted at a compost facility does not depend on its origin (renewable or fossil).

Something is biodegradable and compostable if living things such as fungi and bacteria can break it down in the environment. Biodegradable and compostable bags are made from plant-based materials like cornstarch and wheat as opposed to petroleum. ... Biodegradable bags do not break down in marine environments at all.

The basic difference between biodegradable and non-biodegradable is that biodegradable items decompose or break down naturally. ... Large volumes of non-biodegradable waste take up excess waste and are potentially damaging to the environment.

Plants and animals suffer less harm from toxic chemicals in the environment. Lower potential for global warming, ozone depletion, and smog formation. Less chemical disruption of ecosystems. Less use of landfills, especially hazardous waste landfills.
