How to manage Agricultural Solid Waste?
Around 350 million tonnes of the waste generated are organic agricultural wastes, 290 million tonnes are inorganic waste from the mining and industrial sectors, and 4.5 million tonnes are hazardous by nature.
Therefore, proper and organized management of agricultural solid wastes is required in the agricultural sector, and the industry that processes agricultural products.
Agriculture: Backbone of Indian economy
In India, agriculture is the backbone of the economy, and one of the major contributors to the resource sector. Agriculture is an industry that employs millions of people. In order to meet the need for food, and the supply of food products that has increased along with the population, many people are engaging in modern agriculture. Modern agriculture makes use of artificial fertilizers, as well as the most recent farming methods.
Modern gardening techniques are also being used by people. Because there is a huge demand for animal goods, like milk and meat, manufacturers have discovered techniques to boost efficiency and cut production costs per unit. The growth in production is being aided by chemicals, like fossil fuels, inorganic fertilizers, insecticides, and superior production species genetics. Therefore, a huge amount of liquid as well as solid waste is generated, by these unregulated agricultural activities.
Why is proper handling of agricultural waste important?
After harvest, materials like straw, sugarcane waste, plants, grass, etc. are used for livestock feeding, whereas leftovers like feed, herbs, and weeds are typically dried and burned in the field, or else farmers will leave the leftovers in the field for several days.
This can occasionally result in anaerobic conditions, which can generate foul odours and serve as breeding grounds for numerous microorganisms, which can spread diseases. Farmers’ burn the dry waste left behind, after harvesting the crops, releasing smoke and ashes into the atmosphere, and causing air pollution. It is a risky action, because there is a chance that it will catch fire because of the natural wind flow, which might be disastrous.
Solid waste generation through agricultural activities
Due to the scale of agriculture, the wastes produced by it must be properly managed, through an agricultural waste management programme. Agricultural wastes contain a variety of chemicals, tiny metal particles, medications, and infections, and if they are not properly disposed of, they could harm both the environment and people.
When fertilizers are administered to crops, the crops absorb nutrients, while other substances in the soil are typically rendered harmless. By keeping manure and contaminated waters out of surface and groundwater, the waste management programme seeks to protect the environment and living things.
What is the possible solution?
Compost is the fundamental waste management strategy for agriculture. Vermi-culture is a biotechnological technique for composting agricultural waste. Agricultural waste includes biodegradable cellulose and hemicellulose components, which when broken down, provide plants with rich nutrients. Cow-dung, which comes from livestock and is full of nutrients and microbes, can also be utilized as manure, and is frequently available in rural regions.
Using advanced technologies, such as organic waste recyclers, from manufacturers like Netsol Water, also help to minimize organic waste, saves landfill spaces, and avoids methane generation, as well as saves time, money and your effort.
Additionally, efforts are made to transform agricultural waste into biogas, which is a form of energy. As more people become aware of renewable energy sources, this will become a trend. Contact Netsol Water for agricultural solid waste management, and manufacturing of organic waste recyclers.
