, QUESTION 1
1.1 Decomposition in landfills refers to the process of breaking down organic materials
into simpler substances. This process is essential for managing waste and
reducing the environmental impact of landfills.
Types of Decomposition: There are several types of decomposition that occur in
landfills, including:
1. Aerobic Decomposition: Aerobic decomposition occurs in the presence of
oxygen and is typically faster than anaerobic decomposition. This process
involves the breakdown of organic materials by microorganisms that require
oxygen to function.
Examples of products that undergo aerobic decomposition:
Food Waste: Food waste, such as fruit and vegetable scraps, can undergo
aerobic decomposition in landfills. This process involves the breakdown of
organic materials by microorganisms that require oxygen to function.
Yard Trimmings: Yard trimmings, such as leaves and grass clippings, can
undergo aerobic decomposition in landfills. This process involves the
breakdown of organic materials by microorganisms that require oxygen to
function.
2. Anaerobic Decomposition: Anaerobic decomposition occurs in the absence
of oxygen and is typically slower than aerobic decomposition. This process
involves the breakdown of organic materials by microorganisms that do not
require oxygen to function.
