glass recycling

Introduction :

Glass is 100% recyclable and can be recycled forever without lack of purity or quality. Glass is manufactured from readily available domestic products such as sand, soda ash, limestone and “cullet,” the industrial term for ready-to-use recycled glass. Recycled glass can be used to replace up to 95% of raw materials. Glass consists primarily of silica, a natural raw substance like sand. Glass is unlikely to pollute the atmosphere or impact human health and can thus be quickly reused and recycled. Glass recycling is well known all over the globe.

Manufacturers benefit from recycling in several ways. Recycled glass decreases raw material pollution and usage, prolongs the life of plant facilities, such as furnaces, and saves energy. The containers from recycled glass are still required because glass manufacturers need high-quality recycled glass containers to meet consumer demands for new glass containers. Recycled glass is still part of the formula for glass, and the more it is used, the greater the decrease in energy used in the furnace.

Major issues with glass

Waste haulers carry the goods to a transfer station after the recyclables are picked up at the curb. It is then moved to an MRF (Material Recovery Facility). Factory machines and staff of the facility shall sort materials using conveyor belts, screens, optical scanners, forced air and magnets to classify and group materials together. The sorted materials are then bailed and sold to the market to be made into new products. While it’s convenient for residents to mix recyclables in the same bin, the sorting process for mixed recycling isn’t perfect.

Machines and employees at the MRF cannot remove all the contamination. Broken glass fragments are one of the main pollutants. The glass fragments are attached to paper, cardboard, and other recyclables that contaminate the bails and decrease their market value. The glass itself that is sorted is polluted with bits and pieces of other objects such as small pieces of paper, bottle caps, straws and metal. In order for it to be recycled, there is a cost to clean the bottle. Most MRF glass is delivered to landfills as an Alternate Day Cover (ADC) and is never recycled to a new bottle or container. Furthermore, on machinery, the glass is strong, accelerating wear and tear on conveyor belts, displays and other moving parts.

Know what acceptable and what not acceptable in glass recycling

It is important for you to recycle only acceptable glass. Unacceptable items will contaminate the entire load of the truck and either will be rejected or your city contamination fees will be charged.

Acceptable :

Not Acceptable :

  • Mirrors
  • Drinking glasses
  • Ceramic cups/plates 
  • Clay flower pots
  • Crystal
  • Lightbulbs
  • Window glass
  • Ovenware

Glass can be recycled forever. A million times the same glass can be recycled to create bottles and jars of the same size. However, small quantities of some materials mixed with glass can cause contamination. It is also important to know what forms of glass can and cannot be recycled.

Basic process of glass manufacturing

The glass comes in its original form from three primary virgin materials: sand, soda ash and limestone. Both virgin or recycled materials are melted in a furnace at a heat of around 1500 degrees Celsius. The materials are melted into a liquid or a molten state, which is then dissolved into a mould. Air flowing into the mould produces the shape of a bottle or glass. When cooled down, the bottles and jars are ready to be filled.

How waste glass is affecting the environment?

By producing glass from virgin materials, we kill our property, use resources and increase the need to drill for oil and dig for minerals. This causes harm to our environment.

Resources and the land that uses virgin materials for glass manufacturing mean that we take out of the soil an immense amount of resources, such as bauxite, iron-ore and sand. Although the resources needed for the production of glass are not in short supply, the mining is very damaging for the land and uses natural resources such as oil and coal.

The processing of glass is extremely energy-consuming with the extraction and transport of raw materials. The glass itself is created by the melting of materials at a very high temperature using an enormous amount of energy. This produces masses of CO2, a greenhouse gas which contributes to global warming.

Americans dispose of about 10 million metric tons of glass a year. Most of it ends up in the trash. Only about one-third gets recycled. Any recycled object is one less to be buried in our rapidly filling landfills. What’s more – it takes one million years for glass to spontaneously break down. This ensures that any piece of glass that has ever been sent to the landfill is still sitting there, taking up valuable space.

Know How Glass Recycling Works

Why should we recycle?

By making products from recycled materials instead of virgin materials, we conserve land, save landfill space, reduce energy use and lessen the need to drill for oil and dig for minerals. Glass can still be recycled. Many places in the U.S. have a glass recycling system so that glass can be recycled and reused for the manufacture of glass. Recycled glass reduces the expense of recycling and disposing of glass combined with our garbage.

How is recycled glass made?

The method of recycling glass creates a crushed glass product called ‘cullet.’. Cullet is also combined with virgin glass materials for the development of new end goods. The processing of new recycled glass saves energy because recycled glass is melted at a lower temperature than virgin raw material and therefore needs less energy in the production process.

All glass can be recycled, but there are certain rules on what you can put in your bin. Household glass in kerbside recycling collections or bottle bins in public areas such as shopping malls may be returned for recycling. 

In the bin of the kerbside

Yes 

Clear, green or brown (amber) bottles – like wine, beer, juice, soft drinks and bottles of sauce 

Glass pots, such as jams and spreads 

No 

Since this material melts at a temperature different from normal glass. 

  • Drinking glass 
  • Ceramics – such as pyrex and cornware 
  • The oven-proof glass 
  • Chinese 
  • The Light Globes-The Mirrors 
  • Window glass and window glass
  • Physical or laboratory glass
  • White, opaque bottle

Benefits of Glass Recycle: Why Recycle Glass?

The recycling of glass is both easy and beneficial. Let’s start with the benefits of recycling glass:

1.Glass recycling is a positive thing for the environment

A glass bottle that is sent to a landfill site will take up to a million years to break down. On the other side, it takes as little as 30 days for a recycled glass bottle to leave your kitchen recycling bin and appear on a supermarket shelf as a new glass jar.

2. Glass recycling shall be sustainable

Glass containers are 100% recyclable, which ensures that they can be recycled twice, again and again with no loss of purity or consistency in the glass.

3. Recycled glass is efficient

Recovered glass from the processing of glass is the main component of all fresh glass containers. A standard glass container is made of as much as 70% recycled glass. According to industry figures, 80 per cent of all recycled glass would potentially end up as fresh glass containers.

4. Glass recycling conserves natural resources

More than a ton of the raw materials used to make new glass are saved by every ton of recycled glass, including 1,300 pounds of sand; 410 pounds of soda ash; and 380 pounds of limestone

5. Recycled glass save energy

Making new glass involves heating sand and other substances at a temperature of 2,600 degrees Fahrenheit, which takes a lot of energy and produces a lot of industrial waste. One of the first steps in the processing of glass is the grinding of glass and the creation of a product called ‘cullet.’ Recycled glass products from slaughtered use 40% less energy than new glass produced from raw materials, since they melt at a much lower temperature.

6. Recycled glass is of use

Since glass is made of natural materials such as sand and limestone, glass containers have low chemical interactions with their contents. As a result, glass can be reused safely. Besides acting as the primary ingredient in new glass containers, recycled glass also has many other industrial applications, from the development of decorative tiles and landscaping products to the restoration of eroded beaches

7.Glass recycling is simple

As I pointed out at the beginning of this article, the recycling of glass is easy. It’s simple since glass is one of the simplest materials to recycle. For one thing, almost all of the curbside recycling services and community recycling centres accept glass. All most people have to do is to recycle glass bottles and jars to take their recycling bin to the sidewalk, or maybe drop off their empty glass containers at the nearest collection point.

8.Glass recycling pays

If you need an extra reason to recycle glass, how about this some U.S. states offer cash refunds for most glass bottles, so in certain places, recycling glass will potentially put a little extra money in your wallet.
