Waste Glass Needs to be Properly Sorted and Recycled
Glass has been part of human history for over 4,000 years. Today, it is ubiquitous—from high-rise buildings to bottles and cans—yet this prevalence brings with it massive amounts of waste glass. Without proper recycling, waste glass hinders waste reduction efforts: collection, transportation, and incineration costs are substantial; it does not degrade naturally when landfilled; and even worse, some waste glass contains heavy metals like zinc and copper, which can contaminate soil and groundwater if discarded arbitrarily.
Statistics show that using recycled glass saves 10%~30% of coal and electricity, reduces air pollution by 20%, and cuts mining-related exhaust emissions by 80%. Recycling one ton of waste glass conserves 720 kilograms of quartz sand, 10 tons of coal, and 400 kilowatt-hours of electricity.
Most recyclable glass originates from waste glass bottles, discarded flat glass, and similar sources. Due to differences in composition and production processes across glass product types, accurate sorting is critical during recycling. Proper sorting not only boosts recycling efficiency but also lowers costs and energy consumption in subsequent treatment stages.
What Are The Types Of Recyclable Glass?
01.Bottle Glass
Bottle glass is the most common type of recyclable glass, typically used for packaging various beverages, spices, and food products—such as bottled water containers, beer bottles, beverage bottles, and spice bottles.
This type of glass product is characterized by hardness, heat resistance, corrosion resistance, and ease of cleaning. After thorough washing, it can be reused directly.
02.Flat Glass
Flat glass refers to clear or colored glass sheets, either flat-mounted or bent, used in construction, furniture, flower stands, vehicles, and other fields. This type of glass product is characterized by high transparency, UV resistance, heat resistance, and fire resistance. After recycling, it can be remade into various glass products.
In glass recycling, cleaning is a critical step for ensuring the quality of recycled glass. Removing residues and stains prevents contamination throughout the recycling process and ensures the recycled glass can be reused to produce new glass products.
RUIJIE Automatic Sorting Equipment
The use of RUIJIE automatic sorting equipment enables automatic sorting of iron, aluminum, and plastics, boosting finished product pass rates. It also reduces production staff numbers and lowers wage costs.
For the automatic sorting and separation of waste glass impurities, our highly intelligent automatic production equipment is essential.
Waste Glass Recycling and Impurity Removal Process
1.The chain feeder ensures uniform feeding for the entire sorting line process.
2.The trommel screen cleans the glass and sifts out impurities.
3.The winnowing machine removes light impurities such as lint, particles, and debris from the glass mixture.
4.The crushing machine will crush the material to facilitate subsequent processing.
5.Iron removal is performed using an Electromagnetic Overband Separator
6.Next, eddy current separator equipment separate the valuable non-ferrous metals.
7.Finally, the color sorter purifies single-color glass, enhancing the recycling quality and market value of waste glass.
Waste Glass Sorting Process Flow Chart
Whether it’s eddy current separators, magnetic separators, or glass sorting machines, we precisely design and manufacture them in a tailor-made manner to meet the needs of glass bottle recycling companies.
RUIJIE eddy current separator can remove loose non-ferrous metal particles (for example:aluminum caps and aluminum rings in used beverage bottles).
Magnetic separators effectively separate iron residues such as metal rings and hoops (e.g., those from bottle necks). Our stainless steel sorting machine can even extract stainless steel springs—including those found in bottle necks.
