This set of Hazardous Waste Management Multiple Choice Questions & Answers (MCQs) focuses on “Process Selection and Facility Siting – Integrated System”.
1. According to CPCB the major criteria considered for selection of technologies are _________
a) Waste quantity
b) Chemical analysis
c) Lead content
d) Mercury content
View Answer
Explanation: According to CPCB the major criteria considered for selection of technologies are the waste quantity, waste characteristics, physical properties and composition of wastes, availability of land, social factors, capital investment, duration of treatment, products market etc.
2. As per CPCB the waste processing technologies are divided into _________ categories.
a) 1
b) 2
c) 3
d) 4
View Answer
Explanation: As per CPCB, the available waste processing technologies can be broadly divided into two categories- biological treatment and thermal treatment.
3. The biological activities depend upon __________
a) pH
b) Chemicals
c) Toxins
d) Temperature
View Answer
Explanation: The biological activities depend upon several criteria- C/N ration, pH value, moisture content, supply of oxygen etc.
4. Vermi-composting can treat oily and spicy waste.
a) True
b) False
View Answer
Explanation: Vermi compost is the end-product of the breakdown of organic matter by particular species of earthworm. It can treat any organic waste, not applicable for oily, spicy, salty or hard and waste that has excessive acidity and alkalinity.
5. The major issues contributing to difficulties in siting hazardous waste facility are _________
a) Uncertainty of risk
b) Area
c) NPL
d) HSP
View Answer
Explanation: The major issues contributing to difficulties in siting hazardous waste facility are the lack of a systems approach, uncertainty of risk, public perceptions of risk, inequities in costs and benefits, institutional distrust, and difficulties in communication about risk.
6. Hazardous waste management requires __________
a) Chemical analysis
b) Systems approach
c) Research
d) NPL
View Answer
Explanation: Hazardous waste management requires a systems approach. The waste production process is a complex, involving numerous opportunities for management to reduce risks, to lower economic costs, and to recycle wastes to beneficial uses.
7. Hazardous facility siting is a __________
a) Chemical analysis
b) Systems approach
c) System activity
d) System analysis
View Answer
Explanation: The deployment of a waste management system requires a network of waste processing, storage and disposal facilities, interconnected by waste transportation links.
8. Current hazardous waste facility strategies tend to be facility-specific.
a) True
b) False
View Answer
Explanation: Most of the state laws governing hazardous nonradioactive waste facility siting are geared to the process for siting a given facility.
