Hazardous Waste Management test 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
Answer: a
Clarification: 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
Answer: b
Clarification: 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
Answer: a
Clarification: 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
Answer: b
Clarification: 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
Answer: a
Clarification: 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
Answer: b
Clarification: 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
Answer: c
Clarification: 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
Answer: a
Clarification: Most of the state laws governing hazardous nonradioactive waste facility siting are geared to the process for siting a given facility.
