The Manufacturing of
Glass Bottles Global
Standards Operation Process
for Sustainability Purpose
(SOP Version Year 2022)
- Glass Bottles & Our Environment
The aim of the glass bottles global standards operation process is to give confidence to all nitrile.com global clients regarding their quality and manufacturing process concern when they order glass bottles, lids and goods safety delivery solutions and use of water or carbonated beverage glass bottles made by conventional techniques and covering the normal methods of bottling and distribution. If it is intended to depart from normal practice, either in container design or manufacture, or in filling, packaging, distribution or marketing, then any necessary additional control and precautions must be discussed between the parties involved.
Glass bottles of a nominal capacity of greater than 1.15 litre (1150ml) are not recommended for packaging water or carbonated drinks. Glass bottles are not recommended for packaging water or carbonated drinks or where carbonation pressures exceed 4.7 bars, except in the case of refillable bottles with a nominal capacity no greater than 180 ml, where carbonation pressure up to 5.3 bars may be used.
This official document also addresses the responsibility of nitrile.com glass manufacturers regarding carbon reduction production, global quality standards and green recyclable policies of nitrile.com factories, including International Standards (ISO), American Standards (ASTM), British, European, International Standards (BS EN ISO) and Japan Industrial Standards (JIS);
Moreover, if the glass bottle product is defective when its safety is not such as persons are generally entitled to expect. When deciding whether a product is defective, the way in which the product is marketed, the instructions and warnings accompanying it, and what might reasonably be expected to be done with it. In the case of carbonated beverages in particular, nitrile.com recommends that all packages for water or carbonated drinks, should carry a guidance note to advise the retailer and consumer that the contents of the package are pressurized and should be handled with care.
Lastly, nitrile.com is keen to pay attention to the recycle of waste problem of glass beverage bottles. Doing so will not only save our limited landfill space but also help us to turn waste into a resource. As you read this document, you will see how our past efforts have led us to the current stage. As always, we welcome your views. We also call on your support - only with that can we create a sustainable global solution for glass beverage bottles.
2. Glass Manufacturing
Commercially produced glass can be classified as soda-lime, lead, fused silica, borosilicate, or 96 percent silica. Soda-lime glass, since it constitutes 77 percent of total glass production, is discussed here. Soda-lime glass consists of sand, limestone, soda ash, and cullet (broken glass). The manufacture of such glass is in four phases: (1) preparation of raw material, (2) melting in a furnace, (3) forming and (4) finishing. Figure 11. 15- 1 is a diagram for typical glass manufacturing.
The products of this industry are flat glass, container glass, and pressed and blown glass. The procedures for manufacturing glass are the same for all products except forming and finishing. Container glass and pressed and blown glass, 51 and 25 percent respectively of total soda-lime glass production, use pressing, blowing or pressing and blowing to form the desired product. Flat glass, which is the remainder, is formed by float, drawing, or rolling processes.
As the sand, limestone, and soda ash raw materials are received, they are crushed and stored in separate elevated bins. These materials are then transferred through a gravity feed system to a weigher and mixer, where the material is mixed with cullet to ensure homogeneous melting. The mixture is conveyed to a batch storage bin where it is held until dropped into the feeder to the melting furnace. All equipment used in handling and preparing the raw material is housed separately from the furnace and is usually referred to as the batch plant. Figure 11.15-2 is a flow diagram of a typical batch plant.
The furnace most commonly used is a continuous regenerative furnace capable of producing between 45 and 272 megagrams (Mg) (50 and 300 tons) of glass per day. A furnace may have either side or end ports that connect brick checkers to the inside of the melter. The purpose of brick checkers (Figure 11. 15-3 and Figure 11. 15-4) is to conserve fuel by collecting furnace exhaust gas heat that, when the air flow is reversed, is used to preheat the furnace combustion air. As material enters the melting furnace through the feeder, it floats on the top of the molten glass already in the furnace. As it melts, it passes to the front of the melter and eventually flows through a throat leading to the refiner. In the refiner, the molten glass is heat conditioned for delivery to the forming process. Figures 11. 15-3 and 11. 15-4 show side port and end port regenerative furnaces.
After refining, the molten glass leaves the furnace through forehearths (except in the float process, with molten glass moving directly to the tin bath) and goes to be shaped by pressing, blowing, pressing and blowing, drawing, rolling, or floating to produce the desired product.
Pressing and blowing are performed mechanically, using blank molds and glass cut into sections (gobs) by a set of shears. In the drawing process, molten glass is drawn upward in a sheet through rollers, with thickness of the sheet determined by the speed of the draw and the configuration of the draw bar. The rolling process is similar to the drawing process except that the glass is drawn horizontally on plain or patterned rollers and, for plate glass, requires grinding and polishing. The float process is different, having a molten tin bath over which the glass is drawn and formed into a finely finished surface requiring no grinding or polishing. The end product undergoes finishing (decorating or coating) and annealing (removing unwanted stress areas in the glass) as required, and is then inspected and prepared for shipment to market. Any damaged or undesirable glass is transferred back to the batch plant to be used as cullet.

- Abstract
- Test methods for thermal shock resistance of glass containers
This test method covers the determination of the relative thermal shock resistance of commercial bottles and jars and is intended to apply to all types of glass containers that are required to withstand sudden changes in temperature in service. The test apparatus consists essentially of a basket for holding the glassware upright, a hot water tank, a cold water tank, and a timed means for immersing and transferring the basket from the hot to the cold bath. Indicating controllers or dial thermometers should be used to maintain the temperatures of the baths. Test procedures included in this specification include pass tests, progressive tests to a predetermined percent of breakage, total progressive tests, and high-level tests.

- Our Eco Responsibilities
With a long-term awareness of environmental protection, nitrile.com aim to become a leader in maintaining sustainable development in the field of glass bottle of carbon neutralization production, and we build advantages of our eco responsibilities;
(a) Achieve a high recovery rate: International experience indicates that mandatory PRSs on glass beverage bottles could achieve a recovery rate ranging from 60% to close to 100%. As a start, we expect that about 80% of all waste glass beverage bottles generated;
(b) Provide a convenient collection system: An annual tonnage of 38,000 means a daily throughput of over 100 tones. That exceeds the combined monthly capacity of all existing voluntary programs. We need more easily accessible collection facilities, including recycle bins specifically designed for glass collection. nitrile.com is also looking for operating several regional collection points to facilitate disposal glass for clients in different country;
(c) Maintain high treatment standards: nitrile.com will set standards and promote professionalism, so that the handling of waste glass beverage bottles will be environmentally sound from collection to transportation to recycling facilities;
- Creation of A Circular Economy
International experience indicates that mandatory recycling program on glass beverage bottles could achieve a recovery rate ranging from 60% to close to 100%. In those Asian jurisdictions described, at least 70% recovery has been achieved. As a start from nitrile.com, we estimate that 50,000 tones could be collected annually from nitrile.com upon successful implementation of our recycling program initiative accounting for about 70% of the glass beverage bottles. This would require a sizable expansion of the current scale of recycling operations and would facilitate the creation of a circular economy.
