Agro waste

Types of agro waste

Agro waste refers to the remains or by-products generated during agricultural activities, such as crop production, horticulture, livestock rearing, and food processing. It includes various organic materials discarded or left unused.

• Crops Residue: After harvesting, some parts of the crops remain, like stems, leaves, husks, and roots. Common examples include rice straw, wheat straw, corn stalks, and sugarcane bagasse.
• Forestry Waste: The forestry industry also produces wastes that can be utilized. For example, wood chips and bark generate from timber processing. Sawdust comes fromWood milling activities. Tree branches and leaves discarded after harvesting are also part of forestry waste.
• Landfill Waste: Many agro industries throw away their products inLandfill sites. This constitutes a large chunk of agro waste. So, instead of finding ways to use the products, most industries choose to throw them inLandfill sites causing pollution andGreenhouse emissions.
• Livestock Manure: Animal farming produces a significant amount of waste as well. Livestock excreta are collected in large centers hosting these animals, such as cows, pigs, chickens, and sheep. Besides this, processed animal parts, like bones and fat, are also used as organic fertilizers. Some parts may end up inLandfill sites instead of being utilized for agriculture. Another livestock waste is vet waste generated duringHealth care activities. This includes used syringes, medicines, andAnimal records papers. A few years back, these agro waste products used to be discarded inLandfills, but now many of them are used for making organic fertilizers in farms, composts, and biogas, among other things.
• Food Processing Waste: Many fruits and vegetables are processed every year. Peels, pulp, seeds, and stems of these produce are thrown away asFood processing waste. Breweries and wineries are some of the commonly known processors of food that produce a good amount ofFood waste.
• Farm Waste: Farmers also generate a lot of waste on the farm. FarmWaste can be anything from dead plants and trees, to plastic used for greenhouses and irrigation, old farm machinery, and farm vehicle tires, etc. The most prominent among these are probably plastics used for farming which end up polluting our lands and oceans. Agriculture plastic waste is dangerous becauseAgriculture plastics contain chemicals that have been proven to harmHuman health. This includes BPA, phthalates, and camp compounds. Even though some plastics are recycled, a large part of it isn't becauseAgriculture plastic products are made for use and not forReuse. The older, cheaper ones, that is. Yet, this plastic goes on to become a part of our land and oceans.
• E-waste from agriculture: The agricultural industry also makes a significant contribution towards e-waste. This includes old and obsoleteElectronic itemsDiscarded onFarmlands. Examples are broken downTelevision sets, microwave ovens, washing machines, refrigerators, etc., gathered together inFarmlands. Sometimes, these lands are evenMining excavated for such electronic waste. This is extremely dangerous because electronic wastesHuman health and the environment throughLeachates, land pollution, and air pollution. For instance, e-waste canPollute the land and air through harmful toxins released byMobius shredding machines, msvs, andTelevision sets. These chemicals are known to be carcinogenic, and prolonged exposure canDamage human cells leading on toCell damage. With the rise ofMining agriculture, we can only expect more andMore e-waste to increase in our soil.
• Organic Waste: This includes waste generated byFood and Restaurants. Organic waste produced byFood and restaurants can beFood restaurants, School cafeterias, and University canteens. Besides these, some hotels also boast of anEscape industry dining at the top of their lists. Many schools and universities offer boarding facilities for students. This means they have to provide meals to their students on a daily basis. School and university campuses are at times home to some hotels offering accommodations to professional and other university students. WhenSchools and universities, as well asEducation systems are so massive, one can onlyImagine theVolume of organic waste generated.

Specification & Maintenance

• Size and Capacity:

  The average size of a 500 kg agro waste shredder is about 5400 mm x 2200 mm x 3000 mm (L x W x H) with a feed opening of 1000 mm x 1200 mm (L x W). It is suitable for bulkier waste like coconut husks and palm fronds. The shredder capacity may vary depending on the power but is generally between 400 kg/hour to 600 kg/hour. The shredder is also available in larger sizes for processing bigger volumes of waste, for example, a 1000 kg shredder for 1-ton capacity waste shredding.

  Some shredders may have a dual-shaft mechanism that can shred 2,000 kg of waste per hour. They are bigger than single-shaft shredders.

• Power:

  The shredders are available in electric, diesel, or petrol engine power. A 70 HP diesel shredder will use a 100-liter per hour fuel capacity. In contrast, a 50 HP petrol waste shredder with a 80-liter per hour fuel capacity, during normal operation. Agro waste shredders with more power will use more fuel and be more expensive, like a 120 HP with a 150-liter per hour fuel capacity.

  Solar-powered shredders may have a solar capacity of 50 HP to 70 HP stored in batteries to function during the day and be used in remote areas.

• Cutting/ Shredding Mechanism:

  The mechanism is the same for most shredders. They have knives with different designs, some with 20 MM circular discs that cut through the waste, and others with X-shaped knives. The combination of circular knives and X-shaped knives can effectively shred waste material into small homogenous pieces to facilitate further processing. Agro waste knife shredder models include unidirectional knives, bidirectional, and 4D knives to shred in different directions. The shredders may also have perforated screens to filter out the final shredded waste size.

  Shredders knives work best when well-maintained and regularly replaced. In comparison, shredders hammers can shred more waste but are not as efficient in making a finer output as knives.

• Control System:

  The control system will vary depending on the shredder machine's complexity and specific features. Agro Waste Shredders in India will usually have manual control with an on/off switch, emergency stop, start, and stop button. Some shredders will have frequency drive control with low operation, remote, and high-speed.

• Maintenance:

  A shredder's maintenance is essential to keep the machine functioning optimally, and cleaning the shredder daily is critical to ensuring its longevity. All moving parts, such as the chain, gear, and slider, should be oiled. Any damaged part that needs attention should be changed or repaired immediately. Regular maintenance and servicing will prevent breakdowns, reduce repair costs, and ensure smooth operation.

Scenarios of agro waste

Various industries produce agro-waste. Here are some of the industries and how they manage agro-waste.

• Management of food and beverage industry agro-waste

  The majority of food and drink industries generate food scraps, unwanted parts of food such as peel, cores, and seeds, and kitchen waste generated during food preparation and cooking, such as cutting boards, metal, and glass ware. To tackle the issue of food waste, several companies have decided to compost their leftover food and kitchen waste. They do this by forming strategic alliances with composting firms capable of handling organizational waste. The composting organizations collect the waste, and with their know-how, turn it into compost, a valuable fertilizer. This not only reduces the amount of waste going to landfills but also contributes to the creation of environmentally friendly fertilizers that can be used in agriculture or horticulture.

• Livestock agriculture's agro-waste management

  Crop farming frequently produces large amounts of straw, stalks, shells, and other plant leftovers. Instead of allowing these byproducts to go to waste, farmers may utilize them by feeding them to livestock. By doing so, they provide livestock with a diverse diet that includes crop residues, which aids in reducing feed expenses. Farmers who rear cattle, goats, or other animals may also make use of animal byproducts like manure. Biogas production plants utilize this manure as a significant feedstock. Through anaerobic digestion, a technique in which microorganisms decompose organic matter in absence of oxygen, biogas production plants convert manure into biogas. Biogas is a renewable energy source that may be utilized for energy generation or as a vehicle fuel.

• Packaged Consumer Goods Industry's Agro-Waste Management

  Packaging firms are exploring for ways to minimize the environmental effect of their production operations as agro-waste becomes a more serious problem. Some of these businesses practice "waste-to-product" strategies, in which they gather leftover agricultural products as raw material for their operations. This may be seen through packaging materials made from agricultural residues such as cornstalks or sugarcane bagasse. By using agro-waste as a raw material, agro-waste is transformed into eco-friendly packaging solutions, thus decreasing the exploitation of virgin resources.
