What Are Biodegradable Substances/Waste? Biodegradable substance is a form of substance originating naturally from plant or animal sources, which may be broken down into carbon dioxide, water, methane or simple organic molecules by action of bacteria, fungi and other living organisms by composting, aerobic digestion, anaerobic digestion or similar processes. Biodegradable substances upon braking up are converted into simple organic matter and are thus assimilated in the soil and thus become a part of the carbon cycle of the atmosphere. Common biodegradable substances include food waste like vegetable and fruit peels, dead plants and animals, chicken, egg shells, paper materials, leather, cotton, cattle dung, garden waste like grass, leaves etc. What You Need To Know About Biodegradable Substances • Biodegradable substance is a form of substance originating naturally from plant or animal sources, which may be degraded by other living organisms. • Biodegradable substances are categorized as organic substances. • Biodegradable substances change their form and structure over time and become harmless. • Microorganisms or microbes such as fungi, bacteria and other living organisms have the ability to decompose the biodegradable substance into the soil. • Biodegradable substances include food waste like vegetable and fruit peels, dead plants and animals, chicken, egg shells, paper materials, leather, cotton, cattle dung, garden waste like grass, leaves etc. • Biodegradable substa...

The polymers which can decompose in a few days are decomposed by the action of microorganisms and are known as Biodegradable Polymers. The polymers which are not decomposed by the action of microorganisms and are referred to as non-biodegradable polymers. To control these diseases and infections, we have started using eco-friendly synthetic polymers. This kind of polymers consists of similar functional groups as that of the biopolymers. They can be synthetically made by adding molecul...

We often counter terms like ‘biodegradable’ and ‘non-biodegradable’ in a variety of things and products around us. From household items to the food we eat, basically, everything can be labeled in either of the two categories. So, what is this stuff all about and why is it so important to know the difference between them. Content: Shares Vs Debentures • • • Definition of Biodegradable Substances The term ‘Biodegradable’ is used for those things that can be easily decomposed by natural agents like water, oxygen, ultraviolet rays of the sun, acid rains, micro-organisms, etc. One can notice that when a dead leaf or a banana peel is thrown outside, it is acted upon by several micro-organisms like bacteria, fungi or small insects in a time period. The natural elements like oxygen, water, The natural elements like oxygen, water, moisture, and heat facilitate the decomposition thereby breaking the complex organic forms to simpler units. The decomposed matter eventually mixes or returns back to the soil and thus the soil is once again nourished with various nutrients and minerals. Definition of Non-Biodegradable Substances Those materials which cannot be broken down or decomposed into the soil by natural agents are labeled as non-biodegradable. These substances consist of plastic materials, metal scraps, aluminum cans and bottles, hazardous chemicals etc. These things are practically immune to the natural processes and thus cannot be fed upon or broken down even after thousands of ...

Biodegradable polymers is an important chapter in CBSE class 12th Chemistry. Polymers play a significant role in our lives these days. There are different types of polymers and are used for different purposes. There are polymers that are resistant to the process of environmental degradation and are held responsible for the accumulation of polymeric solid waste materials. These solid wastes cause acute environmental problems and remain undegraded for quite a long time. With the increasing use of polymers, waste disposal of these products is also posing a serious problem. Biodegradable polymers were discovered with the objective to control the damage caused to the environment during their disposal. Biodegradable polymers are comparatively easy to be decomposed by microorganisms. In this article, let’s learn everything about biodegradable polymers examples. Biodegradable Polymers: Definition Biodegradable polymers can be easily degraded by microorganisms within a reasonable period, ensuring that biodegradable polymers and their degraded products have a minimal environmental impact. These polymers are broken into small segments by enzyme-catalysed reactions, and microorganisms produce these enzymes. Biodegradable Polymers: Formation Inserting hydrolysable ester groups into the polymer chain is one way of making a biodegradable polymer. For example, if the following acetal is added to an alkene undergoing free radical polymerisation, ester groups may be introduced into the poly...

A modified plastic (left) breaks down after just three days in standard compost (right) and entirely after two weeks. (UC Berkeley photo by Ting Xu) Biodegradable plastics have been advertised as one solution to the plastic pollution problem bedeviling the world, but today’s “compostable” plastic bags, utensils and cup lids don’t break down during typical composting and contaminate other recyclable plastics, creating headaches for recyclers. Most compostable plastics, made primarily of the polyester known as polylactic acid, or PLA, end up in landfills and last as long as forever plastics. University of California, Berkeley, scientists have now invented a way to make these compostable plastics break down more easily, with just heat and water, within a few weeks, solving a problem that has flummoxed the plastics industry and environmentalists. “People are now prepared to move into biodegradable polymers for single-use plastics, but if it turns out that it creates more problems than it’s worth, then the policy might revert back,” said Xu is the senior author of a paper describing the process that will appear in this week’s issue of the journal Nature. The new technology should theoretically be applicable to other types of polyester plastics, perhaps allowing the creation of compostable plastic containers, which currently are made of polyethylene, a type of polyolefin that does not degrade. Xu thinks that polyolefin plastics are best turned into higher value products, not com...
