WHAT GETS RECYCLED
Many items can be recycled, including aluminum cans, glass bottles, newspapers, magazines, and plastics. Composting is also a form of recycling. It involves saving certain food wastes and mixing them with grass clippings and leaves. This creates a nutrient-rich mixture that can be used in gardens. Even water can be recycled. Before water is reused, it is cleaned and purified at a wastewater treatment plant.
TYPES OF RECYCLING
There are two types of recycling: internal and external. In internal recycling, the waste products from manufacturing processes are reused within the same factory. For example, when copper tubing is being made, the ends of the tubes are usually trimmed. These copper ends are melted down and used to make new tubing.
In external recycling, people collect recyclable materials. The recyclables are brought to a recycling facility, where they are sorted, cleaned, and prepared to new goods.
IMPORTANCE OF RECYCLING
Governments and groups that try to protect the environment have encouraged people to recycle. They say that recycling is important in several ways. It reduces pollution of air, water, and land. It also protects natural resources such as trees, minerals, and oil. These do not get used up as quickly if people can reuse existing products made from these resources.
