Bottles in different colours Mixed colour glass cullet Public glass waste collection point for different colours of containers. Glass recycling is the processing of waste glass into usable products. [1] Glass that is crushed or imploded and ready to be remelted is called cullet. [2] There are two types of cullet: internal and external.
Glass disease, also referred to as sick glass or glass illness, is a degradation process of glass that can result in weeping, crizzling, spalling, cracking and fragmentation. [ 1 ] [ 2 ] Glass disease is caused by an inherent instability in the chemical composition of the original glass formula. [ 3 ]
Glass bottles and glass jars are found in many households worldwide. The first glass bottles were produced in Mesopotamia around 1500 B.C., and in the Roman Empire in around 1 AD. [ 1 ] America's glass bottle and glass jar industry was born in the early 1600s, when settlers in Jamestown built the first glass-melting furnace.
A key factor with glass milk bottles is the number of cycles of uses to be expected. Breakage, contamination, or other loss reduces the benefits of returnables. A key factor with one-way recyclables is the recycling rate: In the US, only about 30-35% of high-density polyethylene bottles are recycled.
For bottle-to-bottle recycling, the bottles have to be decontaminated which was achieved by introducing "super-clean recycling processes," which in the US was done for the first time in 1991. [5] These processes clean "recycled PET flakes to contamination levels similar to virgin PET pellets," so that they can be reused as beverage containers. [5]
Things like vegetables may degrade within days, while glass and some plastics take many millennia to decompose. A standard for biodegradability used by the European Union is that greater than 90% of the original material must be converted into CO 2 , water and minerals by biological processes within 6 months.
The deposit per bottle (Pfand) is €0.08–0.15, compared to €0.25 for recyclable but not reusable plastic bottles. There is no deposit for glass bottles which do not get refilled, but there are many glass bottles that do get refilled – best known is the Normbrunnenflasche, a 0.7l bottle used for carbonated drinks with a deposit of €0.15 ...
The creation of sparks from metals is based on the pyrophoricity of small metal particles, and pyrophoric alloys are made for this purpose. [2] Practical applications include the sparking mechanisms in lighters and various toys, using ferrocerium; starting fires without matches, using a firesteel; the flintlock mechanism in firearms; and spark testing ferrous metals.
