Machines Needed To Recycle Waste

Recycling machines are not one huge black box, but are varied in purpose and complexity.

At all stages of recycling, vehicles transport materials. When sorted, bulk recyclables may be moved by standard trucks or rail cars, but specialized collection vehicles often begin the process. Where municipal recycling programs rely on some consumer sorting of waste, this sorting needs to be maintained. Trucks with various bins allow collectors to place pre-sorted materials into separate compartments.

Roll-off containers are particularly suited for recycling programs because materials can be collected in the bins at drop-off points or transfer stations, and then the entire bin is loaded on a truck without having to handle the collected material again.

Recycling machines in a materials recovery facility are of varied types, from simple to highly technical electronics.

Central to most sorting processes is a system of conveyors which move the materials through the linear process of separating recoverable items. When vibration is added to the belt, materials are spread out for more successful sorting.

A hammer mill is a technically simple machine which is used to beat waste into small pieces. Huge hammermills have long been used to shred vehicles. They are particularly useful for products with multiple components, such as cars or electronic waste. The shredded pieces are more uniform, have a greater surface area, allowing recovery of small amounts of valuable materials such as precious metals.

Machines which crush glass allow that product to be sorted from paper and plastic by gravity . Magnets are a standard component of recycling machines, to remove ferrous metals. Eddy current producing machines can separate non-ferrous metals from plastics because metals are affected by electricity.

Simple mechanical processes, such as rotating paddles or cog-wheels are used in machines to separate lightweight, flat paper products from more dimensional waste such as containers.

Highly technical electronics control other machines to identify and separate individual metals, types and colors of paper or plastic. Various types of sensors locate a desired piece of scrap, and machines with directed air jets force the item into the correct bin.

Once a large quantity of a particular material is collected, it must be prepared for transport to a reprocessing facility. The most commonly used machine for this purpose is a baler. Paper, plastic or aluminum is compressed into a standard size and weight bundle.

The process of sorting and recycling municipal and industrial waste is becoming increasingly complex, but at the same time, more efficient and successful. A variety of machines make this possible.
