Composting is an aerobic process and a large fraction of the degradable organic carbon (DOC) in the waste material is converted into carbon dioxide (CO2). CH4 is formed in anaerobic sections of the compost, but it is oxidised to a large extent in the aerobic sections of the compost.
Which of the following is an example of the biological transformation of solid waste?
The most commonly used biological transformation process is aerobic composting. The most commonly used thermal transformation process is incineration. Waste transformation is undertaken to reduce the volume, weight, size or toxicity of waste without resource recovery.
What is biological solid waste?
Biological waste is any material that contains or has been contaminated by a biohazardous agent. Biological waste includes, but is not limited to; Petri dishes, surgical wraps, culture tubes, syringes, needles, blood vials, absorbent material, personal protective equipment and pipette tips.
Which of the following method of waste management is biological?
Composting and anaerobic digestion – Environmental benefits of resource recovery. The biological treatment of waste materials primarily focuses on stabilisation of organic matter in order to avoid gaseous emissions after waste disposal. … The retrieval of chemical products from waste materials is also under discussion.
What is transformation in solid waste management?
Transformation processes are used to reduce the volume and weight of wastes requiring disposal and torecover conversion products and energy. The organic component of municipal solid wastecan be transformed by a variety of chemical combustion) and biological (aerobic composting) processes.
Is a biological method of disposal of Municipal Solid Waste?
Hence, it can be concluded that composting is a biological method of disposal of Municipal Solid Waste.
What are the methods of solid waste management?
Here are the methods of solid waste disposal and management:
- Solid Waste Open Burning.
- Sea dumping process.
- Solid wastes sanitary landfills.
- Incineration method.
- Composting process.
- Disposal by Ploughing into the fields.
- Disposal by hog feeding.
- Salvaging procedure.
What happens biological waste?
Incineration: According to the EPA, 90% of biohazardous waste is incinerated. Incineration can occur either on-site or off-site by licensed contractors that specialize in handling infectious materials. … Much of the waste treated by autoclaving and shredding ends up at the sanitary landfill.
What is biological waste treatment?
Biological wastewater treatment harnesses the action of bacteria and other microorganisms to clean water. … Wastewater typically contains a buffet of organic matter, such as garbage, wastes, and partially digested foods. It also may contain pathogenic organisms, heavy metals, and toxins.
What do you mean by biological process?
Biological processes are those processes that are vital for an organism to live, and that shape its capacities for interacting with its environment. Biological processes are made of many chemical reactions or other events that are involved in the persistence and transformation of life forms.
Which of the following is a biological method of disposal of municipal solid waste Mcq?
Which of the following is a biological method of disposal of municipal solid waste? Solution: Explanation: Composting is a biological method of decomposing the municipal solid waste under aerobic and anaerobic condition. It results in the production of humus.
Which of the following solid waste describe the term municipal solid waste?
4. The term ‘Municipal Solid Waste’ is used to describe which kind of solid waste? Explanation: The term ‘municipal Solid Waste’ is generally used to describe most of the non-hazardous solid waste from a city, town or village that requires routine collection and transport to a processing or disposal site.
Which process improves efficiency of solid waste management?
Finally load reduction methods were proposed to improve the efficiency of solid waste management system.
What is transformation of waste?
Transformation means a process of reduction of waste by volume and weight and recovering the energy from them. Physical transformations of solid waste typically involve a change of phase.
What is solid waste management PDF?
Solid waste management may be defined as the discipline associated with the control of generation, storage, collection, transfer, processing and disposal of solid waste.
What is residual waste management?
DEFINITION: Non-hazardous waste material that cannot be re-used or recycled and needs to be sent to energy recovery or disposal. Residual waste includes materials produced by industrial, mining and agricultural operations.
