Environmental Biotechnology Questions and Answers – Biomedical Waste Management

This set of Environmental Biotechnology Multiple Choice Questions & Answers (MCQs) focuses on “Biomedical Waste Management”.

1. Which of the following area has the lowest chance of producing a biomedical waste?
a) Hospitals
b) Clinics
c) Laboratories
d) Agricultural lands
View Answer

Answer: d
Explanation: Hospitals, clinics, laboratories and various research centers generate a lot of biomedical wastes from diagnosis, treatment and disease on various diseases generate wastes that are termed as biomedical waste. But agricultural lands generally produce wastes that are biodegradable in nature, so they are not called as biomedical waste.

2. Which of the following is not a Biomedical waste?
a) Animal waste
b) Microbiological waste
c) Chemical waste
d) Domestic waste
View Answer

Answer: d
Explanation: Domestic waste doesn’t contain any infectious agents and is totally degradable in nature but animal waste contains animal tissue and organs, microbiological waste contains microbiological specimen wastes, chemical waste contains disinfectant chemicals. So, all of these wastes are treated as Biomedical wastes.

3. Biomedical wastes are not infectious.
a) True
b) False
View Answer

Answer: b
Explanation: Biomedical wastes are infectious, they are pathological, pharmaceutical waste that are infectious to living organisms thereby spreading diseases. So, it is really required to dispose of the Biomedical wastes properly to avoid any further contamination.

4. Which of the following is categorized as an incineration waste?
a) Incineration ash
b) Animal waste
c) Solid waste
d) Cytotoxic drugs
View Answer

Answer: a
Explanation: Incineration ash comes from any biomedical wastes that is being incinerated and ignited and burnt to dispose of the biomedical wastes. This prevents further contamination but this also creates Incineration ash, which has the potential of causing a disease and hence, it’s treatment is very necessary for the public health, whereas, animal waste contains animal tissue and organs, Solid waste can be any wastes from the hospitals or labs like cotton, blood tubing, catheters etc. and cytotoxic drugs are used and old expired medicines.

5. Which of the following should not be mixed with other wastes to avoid contamination?
a) Tarry residue
b) Oily sludge
c) Animal waste
d) Vegetable oil
View Answer

Answer: c
Explanation: Animal waste is a type of biomedical waste that contains animal tissue and organs and it is not safe for contamination with other wastes as they are infectious. Tarry residue, oily sludge, are hazardous waste of petrochemical processes which should be handled correctly and disposed of carefully without causing any damage to the environment, but it certainly is not infectious. Vegetable oil doesn’t pose any threat as it’s a kitchen waste and domestic wastes are biodegradable.

6. Which of the following is not a waste treatment method for biomedical wastes?
a) Incineration
b) Chemical disinfecting
c) Autoclaving
d) Sieving
View Answer

Answer: d
Explanation: Sieving is a physical method of separation of bigger molecules and it cannot be used in a waste treatment method, whereas, incineration, chemical disinfecting, autoclaving, encapsulation are the methods used for waste treatment of biomedical wastes.

7. Which of the following requires special treatment of bacteria?
a) Packaging of waste
b) Labelling of waste
c) Transport of waste
d) Degradation of waste
View Answer

Answer: d
Explanation: Degradation of waste especially biomedical wastes requires some special treatment of bacteria or other microorganisms, whereas, Packaging, labelling and transport of biomedical wastes should be done properly in order to avoid any hazardous contamination of the wastes with the environment and with humans that can be infectious.

8. Which of the following can be used to produce marketable compost from dry solid wastes?
a) Aerobic composting
b) Vermicomposting
c) Anaerobic digestion
d) Anaerobic composting
View Answer

Answer: a
Explanation: Aerobic composting is used to treat dry solid wastes which can thereby produce compost which can be readily marketed, vermicomposting is usually used to treat lignocellulosic waste, anaerobic composting and Anaerobic digestion are the same thing which is used to treat simple organic wastes, hence, Aerobic composting. Is most suitable for dry solid wastes.

9. Which of the following can be used to treat wastes with simple organic matter with high water content?
a) Vermicomposting
b) Aerobic composting
c) Incineration
d) Anaerobic digestion
View Answer

Answer: d
Explanation: Vermicomposting is usually used to treat lignocellulosic waste which are also dry in nature, Aerobic composting is used to treat dry solid waste, Incineration is method to treat wastes by burning i.e. heat, Anaerobic digestion is used to treat wastes with simple organic matter and with high water content which thereby, degrades it and produces better marketable compost.

10. Genetically engineered microorganisms can treat biomedical wastes.
a) True
b) False
View Answer

Answer: a
Explanation: Genetically engineered microorganisms can be used to treat biomedical wastes as it gives a new biological approach to treat the wastes which poses a great threat to the human health. Moreover, it is more environment friendly than any other methods. It can be used to convert the toxic wastes to non-hazardous and non-toxic form.
