(i) Put garbage in a pit (ii) Cover the bottom of the pit with sand (iii) Cover the pit loosely with a gunny bag or grass (iv) Add worms Which of the following shows the correct sequence of the above steps?

Non-biodegradable waste is a type of waste that can not be broken down into its base compounds by micro-organisms, air, moisture or soil in a reasonable amount of time. Non-biodegradable waste is an environmental concern, as it threatens to overwhelm landfills and create disposal problems. Almost all industries generate some amount of non biodegradable waste for eg fly ash,slag,mud which are major concern for the environment.

The correct option is D Cake, wood and grass The correct options are C and D. Explanation of correct option: • Biodegradable wastes are waste materials degraded by natural processes such as microbes. • Fruit peels, cake, wood, and lime juice are biodegradable materials. The explanation of incorrect options: Option A • Non-biodegradable substances are wastes that cannot decompose by natural processes. • Grass and flowers are biodegradable (easily decompose by the microbes). • Leather is non-biodegradable. Option B • Non-biodegradable waste cannot be easily broken down by the action of microbes. • Grass and wood are biodegradable (easily decompose by the microbes). • Plastic is a non-biodegradable material. Final answer: Fruit peels, cake, lime juice, wood, and grass are biodegradable items.

Answer: a Explanation: Bangalore method is a method of composting whereas area, depression and trench method are the land filling method. 9. ______ is a liquid that passes through solid waste and extracts suspended impurities from it. a) Leachate b) Sludge c) Distilled water d) Municipal waste View Answer Answer: c Explanation: Pulverization is the crushing and grinding of municipal solid waste.

In which method of composting, decomposition of anaerobic waste takes place? a) Indian method b) Depression method c) Bangalore method d) Trench method View Answer Answer: c Explanation: In the Bangalore method of composting, decomposition of anaerobic waste takes place. It is better than the Indore method. 15. Which of the following is a biological method of disposal of municipal solid waste? a) Land fills b) Shredding c) Pulverization d) Composting View Answer Answer: d Explanation: Composting is a biological method of decomposing the municipal solid waste under aerobic and anaerobic condition. It results in the production of humus. Sanfoundry Global Education & Learning Series – Environmental Engineering. To practice all areas of Environmental Engineering,

Bio-waste is defined as biodegradable garden and park waste, food and kitchen waste from households, restaurants, caterers and retail premises, and comparable waste from food processing plants. It does not include forestry or agricultural residues, manure, sewage sludge, or other biodegradable waste such as natural textiles, paper or processed wood. It also excludes those by-products of food production that never become waste. Currently the main environmental threat from biowaste (and other biodegradable waste) is the production of methane from such waste decomposing in landfills, which accounted for some 3% of total greenhouse gas emissions in the EU-15 in 1995. The The Landfill Directive does not prescribe specific treatment options for the diverted waste. The most significant benefits of proper bio-waste management - besides avoided emissions of greenhouse gases - would be the production of good quality compost and bio-gas that contribute to enhanced soil quality and resource efficiency, as well as a higher level of energy self-sufficiency. In practice, however, Member States are often inclined not to opt for composting or bio-gas production, and instead choose the seemingly easiest and cheapest option such as incineration or landfilling and disregarding the actual environmental benefits and costs. Unquestionably, landfilling is the worst waste management option for bio-waste. However, for the management of biodegradable waste diverted from landfills, there seems to be ...
