WASTE -TYPES AND MANAGEMENT

WASTE -TYPES AND MANAGEMENT. ROSEANNA FERNANDES.

WASTE. Waste is any substance which is discarded after primary use, or is worthless, defective and of no use. A by-product by contrast is a joint product of relatively minor economic value. A waste product may become a by-product, joint product or resource through an invention that raises a waste product's value above zero. Examples include municipal solid waste (household trash/refuse), hazardous waste, wastewater (such as sewage, which contains bodily wastes ( feces and urine) and surface runoff), radioactive waste, and others..

TYPES OF WASTE. 1. Liquid Waste Liquid waste includes dirty water, wash water, organic liquids, waste detergents and sometimes rainwater. This waste is usually found in households, businesses, and industries . Depending on its source, liquid waste can be classified as either point or non-point source waste. Point source wastewater refers to all manufactured liquid waste. Natural liquid waste, on the other hand, is classified as non-point source waste. 2. Solid Waste Solid rubbish includes a large variety of items that may be found in households or commercial locations. To understand this type of waste better, let’s break it down into five categories : Plastic Waste –consists of bags, containers, jars, bottles made of plastic. Paper/Card Waste – includes newspapers, packaging materials, cardboard, etc. Tins and Metals – can be found in different forms throughout your home or business Ceramics and Glass – consist of broken ceramic cups and plates, glass bottles, etc..

3. Organic Waste Organic waste is also common in almost all households. This waste consists of food waste, garden waste, and so on. While this waste is broken down by micro-organisms over time, it still needs to be appropriately disposed of when generated. 4. Recyclable Rubbish As the name suggests, recyclable rubbish refers to all waste that can be converted to reusable products. A significant percentage of items in construction waste such as masonry, metal, paper, and furniture can be recycled. 5. Hazardous Waste Hazard waste refers to any waste that’s toxic, flammable, corrosive, or reactive. Such waste can be harmful to both you and the environment. Examples of hazardous waste include toxic chemicals and electronic rubbish..

LIQUID/WET WASTE. Wet waste includes cooked and uncooked food, waste from fruits and flowers, fallen leaves, dust from sweeping, etc. Plastic, food product wrappers, rubber, metals, leather, cloth rags, wire, glass and such, fall under the category of dry waste. Wet waste is organic while dry waste is not. things that are quickly biodegradable are wet waste, while things which will take centuries to do so or will never degrade will be counted as dry waste. The thing to note is that both need to be disposed of differently . Vegetable Peels, Fruit Peels, Rotten Vegetables, Rotten Fruits , Left over food, Mango Seeds, Used Tea Bags Used Coffee Powder from Filter Egg Shells, Rotten Eggs Coconut Shells.

SOLID WASTE. Solid waste refers to the range of garbage materials—arising from animal and human activities—that are discarded as unwanted and useless. Solid waste is generated from industrial, residential, and commercial activities in a given area, and may be handled in a variety of ways Solid waste includes garbage, construction debris, commercial refuse, sludge from water supply or waste treatment plants, or air pollution control facilities, and other discarded materials. Solid waste can come from industrial, commercial, mining, or agricultural operations, and from household and community activities..

SEGREGATION OF WASTE. "Waste segregation" means dividing waste into dry and wet. Dry waste includes wood and related products, metals and glass. Wet waste typically refers to organic waste usually generated by eating establishments and are heavy in weight due to dampness. Waste segregation is different from waste sorting. Waste segregation is the grouping of waste into different categories..

DISPOSAL OF WASTE. Keep two bags for dry waste collection, one for plastics and paper and the other for the rest of the household waste. Dispose sanitary waste in a paper bag. Diapers (adults and babies), synthetic sanitary napkins and hygiene-related products are classified as sanitary waste. Keep plastic waste from the kitchen clean and dry before you drop it into the dry waste bin. Keep glass/plastic containers rinsed of food matter. Wet waste should be sent out for composting daily. Try sending dry waste for recycling once every week..

MANAGEMENT. The three R's – reduce, reuse and recycle – all help to cut down on the amount of waste we throw away. They conserve natural resources, landfill space and energy. Plus, the three R's save land and money communities must use to dispose of waste in landfills.

REDUCE. Reduce/Reduction: to make something smaller or use less, resulting in a smaller amount of waste. "Source reduction" is reducing waste before you purchase it, or by purchasing products that are not wasteful in their packaging or use. A key part of waste "reduction" is "conservation"—using natural resources wisely, and using less than usual in order avoid waste.

RE-USE. You can "reuse" materials in their original form instead of throwing them away, or pass those materials on to others who could use them too! Remember, one man's trash is another man's treasure! Here are some examples of reuse... Take along washable cups or travel mugs instead of disposables; a lot of restaurants and stores will be glad to fill or refill your own mug..

RECYCLE. Recycle—don’t just toss everything in the trash. Lots of things (like cans, bottles, paper, and cardboard) can be remade into either the same kind of thing or new products. Making new items from recycled ones also takes less energy and fewer resources than making products from brand new materials.
