Bottle recycling

Last updated

Bottles are able to be recycled and this is generally a positive option. Bottles are collected via kerbside collection or returned using a bottle deposit system. Currently just over half of plastic bottles are recycled globally [1] About 1 million plastic bottles are bought around the world every minute and only about 50% are recycled. [1]

Glass bottles

There are a large number of benefits to recycling glass bottles, not only for the manufacturing of new bottles but also for the production of other materials that can be used in different contexts. Clean glass bottles are 100% recyclable, can be substituted for up to 95% of raw material, and can be recycled ad-infinitum without the loss of purity or quality. [2] Recycled glass also has a variety of uses outside of the production of new bottles. The least beneficial of these uses is when glass bottles are sifted, crushed down, and mixed with food refuse to create dirty mixed cullet. Mixed cullet has few uses outside of being used as and alternative to traditional landfill daily cover. [3] Alternatively, smaller and unrecoverable pieces of glass are ground down into a fine powder and used as a high grade sand alternative for the production of concrete. [4]

Recoverable glass is often sorted by colour as different colour glass has a variety of uses and values. In the United States, recovered green glass is primarily shipped to Europe to produce wine bottles, brown glass is sold domestically to beer bottlers, and clear glass, the most valuable of the three can be used to replace up to 30 percent of virgin material in the production of new glass. [3] In recent years, extended producer responsibility (has come to the forefront of the debate concerning glass bottle recycling due to glass being very easy to clean and reuse, and its innate cradle to cradle design properties. Recycled glass is a necessity, as without it, manufacturers would not be able to keep up with the demand for new glass containers. [2]

Recycling one glass bottle can save enough energy to power a computer for 25 minutes. [5] In fact for every 10% of cullet added to the production of a new bottle, energy usage goes down by 3-4%. [2] Recycling one ton of glass can save approximately 42 kWh of energy which translates to 7.5 pounds of air pollutants not being released into the atmosphere. [6]

PET bottles

PET bottles are mostly recycled as a raw material. In many countries, PET plastics are coded with the resin identification code number "1" inside the universal recycling symbol, usually located on the bottom of the container. [7]

HDPE bottles

HDPE is commonly used in bottles, particularly bottles (or jugs) of milk. Recycling code 2 is applicable. In the US, only about 30-35% of HDPE bottles are recycled. [8]

Legislation

Container deposit legislation are laws passed by city, state, provincial, or national governments. They require a deposit on bottles to be collected when sold and reimbursed when returned.

In May 2018 the Israeli Ministry Impose EUR 12 m Fine on Bottle Manufacturers and Importers that Didn't Meet Collection Targets.

Environmental comparisons

Many potential factors are involved in environmental comparisons of returnable vs non-returnable systems. Researchers have often used life cycle analysis methodologies to balance the many diverse considerations. Often the comparisons show benefits and problems with all alternatives. It helps provide an objective view of a complex subject. [9] [10]

Reuse of bottles requires a reverse logistics system, cleaning and, sanitizing bottles, and an effective Quality Management System. 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 HDPE bottles are recycled.

Recycling Converting waste materials into new products

Recycling is the process of converting waste materials into new materials and objects. The recovery of energy from waste materials is often included in this concept. The recyclability of a material depends on its ability to reacquire the properties it had in its original state. It is an alternative to "conventional" waste disposal that can save material and help lower greenhouse gas emissions. It can also prevent the waste of potentially useful materials and reduce the consumption of fresh raw materials, reducing energy use, air pollution and water pollution.

Reuse of bottles

A reusable bottle is a bottle that can be reused, as in the case as by the original bottler or by end-use consumers. Reusable bottles have grown in popularity by consumers for both environmental and health safety reasons. Reusable bottles are one example of reusable packaging.

PET bottle recycling

Although PET is used in several applications,, as of 2022 only bottles are collected at a substantial scale. The main motivations have been either cost reduction or recycle content of retail goods. An increasing amount is recycled back into bottles, the rest goes into fibres, film, thermoformed packaging and strapping. After sorting, cleaning and grinding, 'bottle flake' is obtained, which is then processed by either:

Zero waste Philosophy that encourages the redesign of resource life cycles so that all products are reused

Zero waste is a set of principles focused on waste prevention that encourages the redesign of resource life cycles so that all products are reused. The goal is for no trash to be sent to landfills, incinerators or the ocean. Currently, only 9% of plastic is actually recycled. In a zero waste system, material will be reused until the optimum level of consumption. The definition adopted by the Zero Waste International Alliance (ZWIA) is:

Zero Waste: The conservation of all resources by means of responsible production, consumption, reuse and recovery of all products, packaging, and materials, without burning them, and without discharges to land, water or air that threaten the environment or human health.

Container-deposit legislation

Container-deposit legislation is any law that requires the collection of a monetary deposit on beverage containers at the point of sale and/or the payment of refund value to the consumers. When the container is returned to an authorized redemption center, or retailer in some jurisdictions, the deposit is partly or fully refunded to the redeemer. It is a deposit-refund system.

Materials recovery facility

A materials recovery facility, materials reclamation facility, materials recycling facility or Multi re-use facility is a specialized plant that receives, separates and prepares recyclable materials for marketing to end-user manufacturers. Generally, there are two different types: clean and dirty materials recovery facilities.

High-density polyethylene Class of polyethylenes

High-density polyethylene (HDPE) or polyethylene high-density (PEHD) is a thermoplastic polymer produced from the monomer ethylene. It is sometimes called "alkathene" or "polythene" when used for HDPE pipes. With a high strength-to-density ratio, HDPE is used in the production of plastic bottles, corrosion-resistant piping, geomembranes and plastic lumber. HDPE is commonly recycled, and has the number "2" as its resin identification code.

Plastic recycling Processes which convert waste plastic into new items

Plastic recycling is the reprocessing of plastic waste into new and useful products. When performed correctly, this can reduce dependence on landfill, conserve resources and protect the environment from plastic pollution and greenhouse gas emissions. Although recycling rates are increasing, they lag behind those of other recoverable materials, such as aluminium, glass and paper. The global recycling rate in 2015 was 19.5%, while 25.5% was incinerated and the remaining 55% disposed of to landfill. Since the beginning of plastic production in the 20th century, until 2015, the world has produced some 6.3 billion tonnes of plastic waste, only 9% of which has been recycled, and only ~1% has been recycled more than once.

Water bottle Water container

A water bottle is a container that is used to hold water, liquids or other beverages for consumption. The use of a water bottle allows an individual to drink and transport a beverage from one place to another.

Glass milk bottle

Glass milk bottles are glass bottles used for milk and are generally reusable and returnable. Milk bottles are used mainly for doorstep delivery of fresh milk by milkmen: retail store sale is available in some regions. After customers have finished the milk, they are expected to rinse the empty bottles and leave it on the doorstep for collection, or return it to the retail store. The standard size of a bottle varies with location, common sizes are pint, quart, Litre, etc.

Glass recycling Processing of waste glass into usable products

Glass recycling is the processing of waste glass into usable products. Glass that is crushed or imploded and ready to be remelted is called cullet. There are two types of cullet: internal and external. Internal cullet is composed of defective products detected and rejected by a quality control process during the industrial process of glass manufacturing, transition phases of product changes and production offcuts. External cullet is waste glass that has been collected or reprocessed with the purpose of recycling. External cullet is classified as waste. The word "cullet", when used in the context of end-of-waste, will always refer to external cullet.

Plastic milk container Plastic bottle used to store commercially sold milk

Plastic milk containers are plastic containers for storing, shipping and dispensing milk. Plastic bottles, sometimes called jugs, have largely replaced glass bottles for home consumption. Glass milk bottles have traditionally been reusable while light-weight plastic bottles are designed for single trips and plastic recycling.

Plastic bottle Bottle constructed of plastic

A plastic bottle is a bottle constructed from high-density or low density plastic. Plastic bottles are typically used to store liquids such as water, soft drinks, motor oil, cooking oil, medicine, shampoo, milk, and ink. The size ranges from very small bottles to large carboys. Consumer blow molded containers often have integral handles or are shaped to facilitate grasping.

Container deposit legislation in the United States Overview of the container deposit legislation in the United States

There are ten U.S. states with container deposit legislation, popularly called "bottle bills" after the Oregon Bottle Bill, the first such legislation passed.

The Ontario Deposit Return Program (ODRP), also simply known as Bag it Back, is a regulation of the province of Ontario, Canada. Its purpose is to divert recyclable materials from landfill or low-quality recycling uses by charging a fee for each alcoholic beverage container sold in the province, and processing the material for re-use or other recycling activities once the containers are returned for a refund of the deposit fee. Customers forfeit the deposit fee if the container is not returned.

Recycling can be carried out on various raw materials. Recycling is an important part of creating more sustainable economies, reducing the cost and environmental impact of raw materials. Not all materials are easily recycled, and processing recyclable into the correct waste stream requires considerable energy. Some particular manufactured goods are not easily separated, unless specially process therefore have unique product-based recycling processes.

Ifco tray

IFCO trays are a type of reusable packaging for transporting fresh food produce. IFCO SYSTEMS is the name of the company that first developed a pooling service for reusable plastic trays for fresh produce in 1992, when the company was founded in Pullach, Germany. IFCO is the acronym for International Food Container Organization.

Reusable packaging is manufactured of durable materials and is specifically designed for multiple trips and extended life. A reusable package or container is “designed for reuse without impairment of its protective function.” The term returnable is sometimes used interchangeably but it can also include returning packages or components for other than reuse: recycling, disposal, incineration, etc. Typically, the materials used to make returnable packaging include steel, wood, polypropylene sheets or other plastic materials.

History of bottle recycling in the United States

The history of bottle recycling in the United States has been characterized by four distinct stages. In the first stage, during the late 18th century and early 19th century, most bottles were reused or returned. When bottles were mass-produced, people started throwing them out, which led to the introduction of bottle deposits. However, during the second stage, after World War II, consumption patterns changed and nonreturnable containers became popular, which littered the environment. Some states implemented "bottle bills" that instituted deposits. The beverage-container industry first implemented private recycling programs and then pushed for municipal curbside recycling as an alternative to "bottle bills". More recently, PET bottles have largely replaced other materials. The United States used to be the front-runner when it came to recycling PET, but European countries have since outpaced the US.

Packaging waste Post-use container and packing refuse

Packaging waste, the part of the waste that consists of packaging and packaging material, is a major part of the total global waste, and the major part of the packaging waste consists of single-use plastic food packaging, a hallmark of throwaway culture. Notable examples for which the need for regulation was recognized early, are "containers of liquids for human consumption", i.e. plastic bottles and the like. In Europe, the Germans top the list of packaging waste producers with more than 220 kilos of packaging per capita.
