Recycling

Recycling.

R ecycling is the process of converting waste materials into new materials and objects. The recovery of energy from wa ste materials is often included in this concept. The recyclability of a material depends on its ability to reacquire the properties it had in its original state..

The two main broad types of recycling methods are:- Internal recycling External recycling.

What is internal recycling?. Internal Recycling..

Example .. For example th e manufacture of copper tubing results in a certain amount of waste in the form of tube ends and trimmings; this material is remelted and recast. Another form of internal recycling is seen in the distilling industry, in which, after the distillation, spent grain mash is dried and processed into an edible foodstuff for cattle..

What is external recycling?. External Recycling..

Examples. An example of external recycling is the collection of old newspapers and magazines for repulping and their manufacture into new paper products. Aluminum cans and glass bottles are other examples of everyday objects that are externally recycled on a wide scale..

The three types of recycling under internal and external..

Primary recycling is where a recyclable material or product can be recovered or reused without altering its current state. A lot of primary recyclables will be repurposed for the same use as it was created for..

Examples. Glassware – dishes, glass jars, etc. Toys – donate to charities, friends or family Electronics – reuse in another area of your business, sell to recover some cost or donate..

Secondary Recycling will be repurposed without having to reprocess them. SO, the material may be reused in a different way than it was initially intended. This often happens with DIY crafts and can make a huge difference in ensuring recyclable material stay out of landfills..

Example. Cut egg cartons in half and use them to plant seedlings. Cut off the top half of a plastic bottle to use it as a plant pot. Reuse of plastic, paper, wood, metals to do any type of DIY project..

It is when the the product is c ompletely breaking down a product into molecules using a chemical process and then turning it into a completely new product This may be done internally or externally. If external, the recyclables are recovered and reprocessed through a public facility. It would involve sorting recyclables and placing them in bins to be transported by a reprocessing facility. Internal recycling would be where no public service is involved. Some factories or manufactures may conduct internal tertiary recycling..

Example. When plastic is melted and chemically reformed, it can be made into clothing such as fleece. Others are made into variety of plastic products..

Recycling saves energy. Recycling helps the environment. R ecycling help climate change. Recycling helps reduce pollution..

Recycling saves energy by reducing the need to make items from scratch. The process of making products from recycled materials is much simpler and less energy-intensive, as recycled materials require much less processing to turn them into usable materials. The need for new products requires a vast amount of energy and labor, and creates huge amounts of waste. Plus, it’s expensive to collect, move and refine the natural resources needed to create products. The very same products can be made with less energy and expense by using recycled materials. Using things more than once means we don’t have to use new resources..

Example. For example, using recycled aluminum cans to make new aluminum cans uses 95% less energy than using the raw material aluminum is made from..

Recycling prevents the emissions of many greenhouse gases and water pollutants, and saves energy. Using recovered material generates less solid waste. Recycling helps to reduce the pollution caused by the extraction and processing of virgin materials..

Examples. Recycling paper and wood saves trees and forests. Yes, you can plant new trees, but you can't replace virgin rainforest or ancient woodlands once they're lost. Recycling plastic means creating less new plastic, which is definitely a good thing, especially as it's usually made from fossil fuel hydrocarbons..

The process of recycling consists of cleaning and sorting items. There are different systems used to recycle, and sometimes the recycling classification is done on the basis of the system used. The materials can be recycled through mixed waste collection, source separation, or commingled recyclables..

This is when all of the products to be recycled are mixed in with the rest of the waste, and then after picking up the materials are sorted out and cleaned. Although mixed waste collection amounts to a lot of recyclable waste, the city doing the pickup doesn’t need to pay for separate collection of recyclables and you don’t have to depend on the public to do it..

Source separation is on the opposite side of the spectrum. Each material is sorted and cleaned before collection ever takes place. The advantage of this type of recycling is that there is much less need for cleaning after collection but the public does have to be educated on what materials are OK to recycle. Although source separation used to be the preferential way to recycle because of the price of sorting, technology has lowered this cost dramatically..

In a commingled system, all recyclables are mixed but garbage is kept separate. This will cut the costs of cleaning after collection but requires help from the public and education services to tell the public what is safe to recycle..

When was recycling invented? Human recycling dates back to ancient times. While the first recorded instance of paper recycling can be dated to 1031 in Japan, ancient cultures commonly reused everyday items long before this – mainly due to lack of resources and lengthy manufacturing processes..

History Of Recycling cont…. 1031 Japan was the first to start recycling..
