Introduction
Vermicomposting is the process that uses worms for the degradation of organic matter into nutrient-rich manure. Worms consume and digest the organic matter and the process of Vermicomposting takes place. The by-products of digestion which are excreted out by the worms make the soil nutrient-rich, thus enhancing the growth of bacteria and fungi. It is also far more effective than traditional composting.
Composting
All organic materials decompose with time. Some of the major organic wastes we throw everyday makeup to food scraps, yard waste, etc. The process of composting starts with these organic wastes being buried under layers of soil and are then left to decay under the action of microorganisms like bacteria and fungi.
This results in the formation of nutrient-rich manure. Also, this process lets the nutrients get replenished in the soil. Besides enriching the soil, composting also increases the water retention capacity. In agriculture, it's the simplest alternative to chemical fertilizers.
Waste Compaction
The waste materials like cans and plastic bottles are compacted into blocks and sent for recycling. This process protects the metals from getting oxidized and reduces airspace need, thus making transportation and positioning easy.
Importance of Waste Management
Causes of waste management are important to know from a tutorial perspective. If not for efficient waste management, the streets would be suffering from filth, lakes and rivers would become very toxic for all times. Human health would be severely affected if careful waste management practices didn't exist. Therefore, the main causes of waste management practices and plays an important role after environmental disasters especially oil spills. The primary purpose of waste management is to make sure that proper actions and activities are undertaken from the initial creation to final disposal. Ignoring the environment’s needs significantly led to the creation of waste management principles.
