Free CHMM Waste Management Questions and Answers

Question 1

The federal law that reduced hazardous waste contamination was which one?

Accepted Answer

RCRA

Answer

The Resource Conservation and Recovery Act (RCRA) is the principal federal law in the United States governing the disposal of solid waste and hazardous waste. Enacted in 1976, RCRA's primary goal is to prevent hazardous waste contamination by regulating the generation, transportation, treatment, storage, and disposal of hazardous waste. It established a 'cradle-to-grave' management system for hazardous waste.

Question 2

Why is waste management not separate from other global challenges like resource sustainability?

Accepted Answer

Valid

Answer

Waste management is intrinsically linked to broader global challenges like resource sustainability because waste represents discarded resources. Inefficient waste management leads to the loss of valuable materials that could be recycled or reused, increasing the demand for virgin resources and contributing to environmental degradation. Effective waste management, therefore, is a critical component of a sustainable resource economy.

Question 3

His confidential memo stated, "I think the economic logic behind dumping a load of toxic waste in the lowest wage country is impeccable and we should face up to that, I've always thought that countries in Africa are vastly under polluted and their air quality is probably vastly inefficiently low compared to los angeles." Just between us, shouldn't the World Bank encourage filthy industry migration to LDCs?

Accepted Answer

Lawrence summers

Answer

The controversial memo quoted in the question, suggesting that 'the economic logic behind dumping a load of toxic waste in the lowest wage country is impeccable,' was attributed to Lawrence Summers. He was the chief economist of the World Bank at the time the memo was written in 1991. The memo sparked significant debate about environmental justice and economic development.

Question 4

is the quick heating of biodegradable trash during the first stages of composting to eliminate moisture and reduce its weight.

Accepted Answer

Bio-drying

Answer

Bio-drying is a process where biodegradable waste is rapidly heated through aerobic biological activity, typically during the initial stages of composting. The primary purpose of this quick heating is to evaporate moisture from the waste, thereby reducing its weight and volume. This process prepares the waste for further treatment or energy recovery, as drier waste is more efficient for incineration or other thermal processes.

Question 5

Make trash management more effective by

Accepted Answer

reducing our trash output

Answer

The most effective way to improve trash management and reduce its environmental impact is by preventing waste generation in the first place. Reducing our overall trash output lessens the burden on landfills, conserves natural resources, and decreases pollution associated with manufacturing and disposal. This approach aligns with the 'reduce' principle of the waste hierarchy, which prioritizes waste prevention.
