Now, in the world, there are many issues which are caused by increased quantity of wastes. The main solution for these problems is the recycle materials. In this report I would mainly write about the glass recycling. It is important to do the glass recycling because glass contains third biggest rate of disposed wastes quantity as you can see on Figure one. “Figure one, https://me810111.wikispaces.com/Waste+Management” It shows that if we recycle glass, we can reduce the huge quantity of wastes.In addition, “Recycling glass containers provides for unmatched production efficiencies and significant environmental benefits.”(Recycling,glass packaging institute, 2015) For example, if we manufacture new glass products, we need silica (from sand), soda ash (from salt) and limestone, which are non renewable resources. They are limited so in future we will be unable to manufacture or use glass materials anymore if we keep manufacturing new glass materials.. Recycling glass also saves the energy because manufacturing of glass materials takes energy in melting resources part. The heat that is necessarily to melt silica and soda ash is up to 1700?degree which is huge and takes energy. When we recycle, the heat for melting is 1,427 and 1,538 so it takes less energy.Therefore, this can be said to other recycle, we have to recycle glass because if we don’t recycle, the landfill for wastes would be filled up immediately and glass is especially takes space because glass is not biodegradable,that means it may never decompose at landfill. This makes it even more important to reuse and recycle glass bottles and jars when we can. If we recycle glass, the quantity of wastes will be decreased that means the space of a landfill is saved and we can use it for long time. As I said in a last paragraph, the solution to these issues is the recycle of glass and there is some scientific technology is used for it. So, this can be said scientific solution. To go over explaining how science is used to recycle glass, Firstly I explain the process of recycling glass. Glass is recycled by following process. Firstly, the consumers put their used glass products on recycle bin. Recyclable products are collected and separated to different types of materials. Glass is taken from the bin and brought to a materials recovery facility. The glass is arranged by colour and washed to remove any impurities.Finally, glass is crushed to small pieces and melted to liquid in order to reconstruct to other glass products or other uses such as brick.There are many parts that using scientific technology. For example, in the melting and remanufacturing process,They are using physics, in detail thermodynamics. In that part of process, they melt glass equipments in liquid. It turns to solid to liquid so it is melting. In this way, science has been used for recycling glass and it is addressing many issues as I explained in the last paragraph. Recycling glass is effective enough for issues that we are on. For example, recycling glass saves huge amount of natural resources including 1,300 pounds of sand, 410 pounds of soda ash 380 pounds of limestone, and 160 pounds of feldspar and all of them are non-renewable. Bottles and jars made from glass are 100 percent recyclable and can be recycled forever with not losing any quality or purity. For every six tons of recycled container glass employed in the production process, one ton of carbon dioxide that would be enhanced is reduced .The amount of energy that is used will drop 2-3% on 10% cullet used in manufacturing process. An stated 80 percent of recovered glass containers are made into new glass bottles, and it can happen quickly. A glass container can go from a recycling bin to a store shelf in as little as 30 days.
