Answer:

From your science class, you may have learned the classification of the types of changes/transformations: physical change and chemical change. To put it simply, physical change is the change between phases of matter of one substance. For example, freezing water (liquid to solid). On the otherhand, chemical change is altering the chemical make-up of the substance you impart change on. This is usually done by some form of reaction like combustion.

Waste management is important because it takes advantage of science to deal with our daily waste. For biodegradable materials, we take advantage of decomposition which is a chemical change. This is usually done through sanitary landfills. Another example is through incineration or burning of wastes. For physical change, recycling can be done.

Hence, waste management involves strategic ways through the use of science to help us solve our community problems such as waste disposal.

I hope it helps. ^^
