Glass Scrap Waste

Glass constitutes just one fraction of societies’ complex waste stream. Glass has been amongst the most successfully recycled components of the waste stream. Glass recycling, where viable, should be promoted but a balance has to be found between recycling and disposal.

Glass:  After Use

Glass is one of the major components of the waste stream, and it accounts for 8-10% of household waste in Europe. Approximately 25 mta of household waste are generated in the UK (including that collected from Civic Amenity Sites, estimated to be approximately 5 million tonnes/ year), most of which is currently landfilled. Glass, therefore, contributes about 1.6-2.0 mta. Most of this is in the form of packaging as bottles and jars. In addition to this there is the glass originating from pubs, clubs and restaurants, as well as other commercial sources. We can, therefore, estimate (with some degree of certainty) that at least two million tonnes of glass waste arises every year.

Progress in Recycling Glass:

As a result of public concern regarding the escalating wastage of the earth’s natural resources and the disposal of society’s waste material there have been considerable efforts made to improve the recovery rate of this domestic resource. However, as far as glass is concerned, mechanical recycling is the only option.

Most of the mixtures present in the glass scrap waste when it arrives at the processing site are removed manually by hand. This particularly applies to incompatible glass types and colour mixing. Once the glass is broken, it is not possible to separate these materials; therefore it is essential to minimize the level of breakage prior to sorting. The greater the degree of breakage the more difficult it is to assess the level of contamination and under these circumstances, preventing the entry of such contaminants into the cullet must be the overriding priority.

The Future of Glass Recycling:

There is some scope, in the UK at least, for further increases in the proportions of ecology cullet used in glass manufacture. Nevertheless there are significant problems which remain to be overcome. As both the demand for higher quality glass and external (environmental and political) pressures to increase cullet incorporation escalate, the requirement for higher quality feedstock will continue to grow. The three aforementioned areas of concern (minimisation of inclusions, better colour separation and reduced glass breakage) need to be addressed to accomplish this.

The key issue in all three areas is education, both of the public and commerce. There has already been much success; there have been consistent improvements in cullet quality with 95% of ecology cullet now being colour segregated at source. However, there are indications that further increases in the use of post-consumer cullet will result in an increasing incidence of inappropriate glass types and inclusions

Recycling glass scrap is one of the many ways we can help reduce pollution and waste. Everyday we throw away tones of rubbish and glass is a significant part of it. Instead of letting landfills pile up with glass objects that are a threat to safety and the environment, we can use it again.

The broken pieces are crushed, sorted, cleaned, and prepared to be mixed with other raw materials like soda ash and sand. The raw materials and glass pieces are melted in a furnace and then shaped into moulds to make new bottles of different colours and sizes. New recycled bottles and jars are made in this way.

In countries like USA, there are kerbside recycling schemes, which have specially demarcated boxes to collect glass that can be recycled. Some supermarkets, car parks and other public areas have glass bottle banks, where you can take your recyclable jars and bottles.

For every glass scrap that is recycled, calculate the saving made in raw materials, reduction in disposal cost, and also calculate the benefit to landfills. You will have to apply this calculation to the total amount of glass containers/bottles used and recycled in your area. Find out what percentage of it is actually being recycled. You can take adult help to speak to the local authorities or visit the local recycling plant to find out the numbers.
