Non Biodegradable Waste
What is non biodegradable waste? Below is the answer for your Understanding?
When we dispose them in a garbage pile, the air, moisture, climate, or soil cannot break them down naturally to be dissolved with the surrounding land. They are not biodegradable. However natural waste and products made from nature break down easily when they are disposed as waste.
List of Non Biodegradable wastes
- Plastic products like grocery bags, plastic bags, water bottles,etc.
- Metals, Metals cans, tins, metal scraps, etc.
- Construction waste, rubber tires, man made fibres like Nylon, etc.
- Computer hardware like glass, cds, dvds, and cellphones, processed wood, cable wires, Styrofoam. Etc.
Effects of Non Biodegradable wastes
- Groundwater Contamination
Long-term exposure to the environment can cause petroleum-based plastics to emit toxic pollutants. Biphenyl A is a chemical used in the production of water bottles and other hard plastics. Low doses of this pollutant have been detected in groundwater sources.
When slow degrading plastics endure high temperatures, they begin to melt and emit dangerous gases into the atmosphere through a process known as out-gassing.
- High Costs of Polystyrene Management
Polystyrene is non-biodegradable foam that is used to package several different kinds of foods.
- Polystyrene can easily float through storm drains and gutters and wind up in the ocean.
Plastic from waste runoff is the largest source of marine debris in the world, according to the U.S. Occupational and Health Administration. Trash and pollution in the world’s oceans can negatively affect tourism and sea-dependent economies.
Polystyrene can also harm marine wildlife. When foam enters the ocean, it has a tendency to break down into smaller, non-biodegradable pieces. Small fish and birds accidentally ingest these pieces, endangering their overall well being.
They also choke drains leading to flooding.
Biodegradation: Microorganisms at Work
- When something is biodegradable, soil, air or moisture decompose it so that it becomes part of the land. Bacteria, fungi and other decomposers break down dead organisms in a natural process that keeps dead material from covering the planet. While most biodegradable substances consist of animal or plant material, humans can create products that decompose, such as egg cartons and paper bags. If a company produces biodegradable plastic, decomposers break down the plastic’s complex organic molecules into simpler inorganic compounds. In May of 2014, Stanford University scientists and Mango Materials teamed up to develop a biodegradable plastic made from waste methane gas.
Effects on Marine Life
- Non-biodegradable plastic containers in oceans and estuaries can harm fish, seabirds and other marine life. Animals that eat plastic can strangle or experience digestion problems. Micro plastics, tiny bits of polypropylene or polyethylene, hide beneath the water and pose a risk as well. As of September 2014, Virginia Institute of Marine Science researchers were developing biodegradable micro beads that break down when microbes in seawater consume them.
Effects on the Land
- The planet has a limited amount of land, and people waste it when they dispose of non-biodegradable materials. Products that do not decompose naturally may reside in landfills and take up space much longer than biodegradable materials. When people litter, some non-biodegradable trash may not even make it into landfills. Instead, it may make its way into forests, parks, fields, and the sea. Styrofoam, also known as foamed polystyrene, is a non-biodegradable substance that can cause environmental problems when it becomes litter. For instance, styrene, a neurotoxin at high doses, can leach out of polystyrene materials when temperatures climb.
Side effects of biodegradable waste
- While people, animals and the environment benefit from biodegradation, it may cause a few problems. Too much biodegradable waste in a water supply can deplete its oxygen. In addition, some types of biodegradable waste, such as cattle manure, can cause health and environmental concerns if too much is produced.
