Why management of wastes is important?Ans. Having a proper waste management can result in the availability of valuable materials to reuse. Reducing, reusing and recycling your waste is important for the environment, and it can also be profitable. It decreases the amount of waste for disposal, saves space in landfills, and can conserves natural resources.Q. Polyethene bags are so useful to us, still we recommend not to use them. Why are polyethene's called a threat to the environment?Ans. Polyethene's are considered as environmental hazards because they are non-biodegradable and are harmful for the environment. The excessive use of polyethene's generates huge quantities of solid waste, which takes thousands of years to degrade. Burning plastic waste produces harmful gases and generates a foul smell. Plastic bags can choke drains, and if eaten by animals, the animals may choke to death.Q. Recently, a ban on plastic bags has been imposed in many places? Is the ban justified? Give reasons.Ans. Yes, the ban on plastics is justified because :(a) Plastics are non-bio degradable.(b) Plastics cause pollution.(c) Plastics release harmful gases when burnt.(d) Plastics may cause life threat to land and aquatic animals.Q. Why is it recommended to carry your own reusable cloth bags for shopping?Ans. It is recommended to carry your own reusable cloth bags for shopping because it will reduce the impact of plastic bags on the environment and minimize the amount of garbage produced.Q. Your locality faces the problem of waste disposal. How will you convince your neighbors that making compost is the solution? Ans. Residents of our street will believe us only when they will see that in practice. So, First we will dig a pit at open place at one corner of our colony and will ask all the residents of our colony to throw their kitchen waste in this pit and then we will cover it with soil. Cover it with the mixture of soil and dung. Five to six weeks later, open the pit and show it to them that their disposed material has been converted into compost manure.Q. Why we should not burn dried plant leaves and husk? What is the best way to get rid of them?Ans. We should not burn dried leaves and husk because burning of dried leaves, husk and other plant parts produces smoke and gases that are harmful to our health. Instead of burning we can prepare compost from Dried leaves, husk and other plant parts.Q. How can you constructively manage and use Rotten kitchen garbage, Dry leaves collected in a garden & Old newspapers.Ans. Rotten kitchen garbage and Dry leaves can be converted into compost which can be used as a manure in kitchen gardens or potted plants. On the other hand Old newspaper can be recycled to make paper bags, greetings cards etc.Q. Give some advantages of waste recycling.Ans. Some advantages of waste recycling are as follows :(a) It helps to reduce pollution.(b) It keeps our environment clean.(c) It saves energy and resources.Q. How Non-Biodegradable components of garbage are managed?Ans. The Non-Biodegradable components of the garbage are separated by Safai Karamcharis. The non-recyclable components of garbage are spread over the landfill areas and then covered with a layer of soil. Once these landfill areas are completely filled up, then they are usually converted into parks or playgrounds.Q. What do we do with the biodegradable components of garbage?Ans. Generally, biodegradable components of the garbage are used to make compost. Compost are usually developed near the landfill areas. For preparing compost, waste materials like fruit and vegetable peel, egg shells, used tea leaves, waste food, dry leaves, newspapers etc. are dumped in a pit. then the pit is covered with soil. After 20-25 days, Garbage turned black in colour and no foul smell is emitted, it means rotting of garbage is complete and compost is ready to use.Q. What is composting? Do you think it is better to use compost instead of chemical fertilizers? Give reason.Ans. Composting is a method of preparing manure, in which biodegradable waste material is allowed to decompose in a pit by the action of micro-organisms. It is better to use compost (manure) instead of chemical fertilizers as compost is chemical free, environment friendly and can be made at home at very low cost.Q. How is compost prepared from kitchen wastes?Ans. The kitchen wastes generally include vegetable and fruit peels, egg shells, waste food etc., which are completely biodegradable. We put these waste into a pit and cover them with soil. After some days, we observe that they are completely degraded. Take them out of the pit and mix it in the soil where you grow your favourite plants. The final form of the wastes mixed with soil is called compost.Q. What is vermicompost? Why can vermicompost not be made from non-biodegradable garbage?Ans. Vermicomposting is a type of composting in which a type of earthworms, often called red worms, acts on the waste and degrades it. Red worms break down the organic matter into nutrient-rich manure. Vermicompost is stable, fine granular organic manure, which enriches soil quality by improving its physicochemical and biological properties. It is highly useful in raising seedlings and for crop production. Vermicompost can not be made from non-biodegradable garbage because Non-biodegradable waste cannot be decayed by red worms.Q. We should not add wastes containing salts, pickles, oil, vinegar, meat and milk products in vermicomposting pit to feed the redworms. Why?Ans. We should not add wastes containing salts, pickles, oil, vinegar, meat and milk products in vermicomposting pit to feed the redworms because it may causes growth of disease-causing small organisms and they may harm redworms and can also slow down the preparation of vermicompost.Q. Why do earthworms are called farmer’s Friend?Ans. Earthworms are called farmer’s friend because of the services provide by them in increasing and improving soil fertility, texture and moisture holding capacity which consequently benefits the crop. They decompose the organic matter into manure and improve the aeration of soil as they dwell in.Q. What is papier-Mache? How does it help us?Ans. Papier-Mache is a paste made from pulp of waste papers and clay used for molding into boxes, trays, etc. This helps in recycling of paper.Q. Why dumping of hospital waste in water bodies is hazardous?Ans. Dumping of hospital waste in water bodies is hazardous because hospital waste contains harmful chemicals, hazardous plastic wastes, discarded syringes, opened plasters, etc. which may harm the aquatic life and pollute the water body.Q. Most of the time we observe that rag pickers suffer from diseases. Why?Ans. Rag pickers work barefoot and without gloves in an unhygienic environment full of contaminated materials. Their entire workplace is actually a breeding ground of mosquitoes which carry various infectious diseases with them. That's why they often suffer from diseases.Q. We should not burn or heat plastics, why?Ans. All kind of plastics releases harmful gases, on heating and burning. These gases cause many health problems including cancer, asthma, etc., which sometimes may cause death.Q. Why plastics are not suitable for storing cooked foods?Ans. Plastics are not suitable for storing cooked food because they emit harmful chemicals when they are exposed to high temperatures. Using plastics cause health problems such as heart disease, diabetes, cancer, etc.Q. Why we should not throw garbage in plastic bags?Ans. We should not throw garbage in plastic bags because when stray animals looked for food in these bags (which are usually knotted) are unable to reach the food and they end up eating the whole plastic bag. Sometimes, they die due to this. The plastic bags thrown carelessly on roads and other places get into drains and the sewer system. As a result, drains get choked and water spills out on the roads which might even create a flood like situation during heavy rain.Garbage in Garbage out class 6 extra questions answers.

Q. What is vermicomposting? Mention the steps for preparing vermicompost.
Ans. Process of conversion of biodegradable wastes into manure using redworms is known as vermicomposting. The product so obtained by vermicomposting is known as vermicompost. Vermicompost is an excellent, nutrient-rich organic fertilizer.
For preparing vermicompost, spread a net at the bottom of pit or a box. Add 1-2 cm thick layer of sand and then spread biodegradable wastes like vegetable and fruit peels, green leaves, husk, etc., and sprinkle some water to make the layer wet. Now buy some redworms and put them into the pit and cover them with gunny bags. Observe the content after 3-4 weeks. If it doesn’t smell bad and there is a loose soil-like material then the process of vermicomposting is complete. Sieve this content and sun dry it.
