Question

what does the zero waste philosophy promote?
a. redesigning resource life cycles to eliminate waste
b. increasing landfill use
c. burning waste to produce energy
d. collecting waste without recycling
what is waste-to-energy?
a. a recycling technique
b. a process that generates energy from burning waste materials
c. a type of biodegradable waste
d. a method of composting organic materials

Explanation:

First Question (What does the zero waste philosophy promote?):

The zero - waste philosophy aims to minimize waste generation. Option a talks about redesigning resource life cycles to eliminate waste, which aligns with the zero - waste goal. Option b (increasing landfill use) goes against zero - waste as landfills are for waste disposal. Option c (burning waste for energy) still produces waste in the form of ash and emissions and is not zero - waste. Option d (collecting waste without recycling) also does not reduce waste.

Waste - to - energy is a process. Option a: it is not a recycling technique as recycling reuses materials, while waste - to - energy burns waste. Option b: it correctly describes waste - to - energy as a process that generates energy from burning waste materials. Option c: it is not a type of biodegradable waste. Option d: it is not a composting method.

Answer:

a. Redesigning resource life cycles to eliminate waste

Second Question (What is waste - to - energy?):
