Acrylonitrile butadiene styrene (ABS) (chemical formula (C8H8)x·(C4H6)y·(C3H3N)z ) is a common thermoplastic polymer. Its glass transition temperature is approximately 105 °C (221 °F). ABS is amorphous and therefore has no true melting point.
Polyethylene terephthalate (or poly(ethylene terephthalate), PET, PETE, or the obsolete PETP or PET-P), is the most common thermoplastic polymer resin of the polyester family and is used in fibres for clothing, containers for liquids and foods, and thermoforming for manufacturing, and in combination with glass fibre for engineering resins.
In materials science, a thermosetting polymer, often called a thermoset, is a polymer that is obtained by irreversibly hardening ("curing") a soft solid or viscous liquid prepolymer (resin). Curing is induced by heat or suitable radiation and may be promoted by high pressure or mixing with a catalyst. Heat is not necessarily applied externally, and is often generated by the reaction of the resin with a curing agent. Curing results in chemical reactions that create extensive cross-linking between polymer chains to produce an infusible and insoluble polymer network.
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:
A closure is a device used to close or seal a container such as a bottle, jug, jar, tube, or can. A closure may be a cap, cover, lid, plug, liner, or the like. The part of the container to which the closure is applied is called the finish.
Wood–plastic composites (WPCs) are composite materials made of wood fiber/wood flour and thermoplastic(s) such as polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC), or polylactic acid (PLA).
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 is the processing of plastic waste into other products. Recycling can reduce dependence on landfill, conserve resources and protect the environment from plastic pollution and greenhouse gas emissions. Recycling rates lag behind those of other recoverable materials, such as aluminium, glass and paper. From the start of plastic production through to 2015, the world produced around 6.3 billion tonnes of plastic waste, only 9% of which has been recycled and only ~1% has been recycled more than once. Of the remaining waste, 12% was incinerated and 79% was either sent to landfills or lost to the environment as pollution.
A water bottle is a container that is used to hold liquids, mainly water, for the purpose of transporting a drink while travelling or while otherwise away from a supply of potable water.
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.
Polyester is a category of polymers that contain one or two ester linkages in every repeat unit of their main chain. As a specific material, it most commonly refers to a type called polyethylene terephthalate (PET). Polyesters include naturally occurring chemicals, such as in plants and insects, as well as synthetics such as polybutyrate. Natural polyesters and a few synthetic ones are biodegradable, but most synthetic polyesters are not. Synthetic polyesters are used extensively in clothing.
Plastic lumber is a plastic form of lumber made of virgin or recycled plastic. It is mostly made of plastic and binders such as fiberglass or rebar; not to be confused with wood-plastic composite lumber. Widely employed in outdoor decking, it is also used for molding and trim and garden furniture such as park benches. Resistant to cracking and splitting when appropriately installed, plastic lumber can be molded with or without simulated wood grain details. Even with a wood grain design, plastic lumber is still easy to distinguish visually from natural timber: the grains are the same uniform color as the rest of the material.
The Emeco 1006, also known as the Navy chair, is an aluminum chair manufactured by Emeco. The 1006 was originally built in 1944 for Navy warships during World War II, but later became a designer chair used in high-end restaurants and by interior designers. In the 1990s, the company began creating designer versions of the 1006 chair, such as the stackable Hudson chair and the 111 Navy Chair made from recycled plastic. Emeco also makes stools, tables, and other furniture. As of 2012, more than one million Emeco 1006 chairs have been produced.
Textile recycling is the process of recovering fiber, yarn, or fabric and reprocessing the material into new, useful products. Textile waste is split into pre-consumer and post-consumer waste and is sorted into five different categories derived from a pyramid model. Textiles can be either reused or mechanically/chemically recycled.
ALPLA, otherwise ALPLA Group is an Austrian, international acting plastics manufacturer and plastics recycler headquartered in Hard, specialising in blow-moulded bottles and caps, injection-moulded parts, preforms and tubes. It is one of the largest producers of rigid plastic packaging solutions worldwide, with a total of 196 production plants in 47 countries worldwide, approx. 23,300 employees and annual sales of € 4.7 billion in 2022. In early 2021, the ALPLA Group announced that it would invest an average of 50 million euros a year until 2025 in the ongoing expansion of its recycling activities.
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, ink, etc. They come in a range of sizes, from very small bottles to large carboys. Consumer blow molded containers often have integral handles or are shaped to facilitate grasping.
Plastics are a wide range of synthetic or semi-synthetic materials that use polymers as a main ingredient. Their plasticity makes it possible for plastics to be molded, extruded or pressed into solid objects of various shapes. This adaptability, plus a wide range of other properties, such as being lightweight, durable, flexible, and inexpensive to produce, has led to their widespread use. Plastics typically are made through human industrial systems. Most modern plastics are derived from fossil fuel-based chemicals like natural gas or petroleum; however, recent industrial methods use variants made from renewable materials, such as corn or cotton derivatives.
Composite lumber is a material that is a mixture of wood fiber, plastic, and some type of binding agent. These ingredients are put together to form a material that is denser, stronger, and heavier than wood alone, a wood-plastic composite.
Emeco is a privately held company based in Hanover, Pennsylvania. The Emeco 1006, known as the Navy Chair, has been in continuous production since the 1940s. Today, Emeco manufactures furniture designed by notable designers and architects such as Philippe Starck, Norman Foster, and Frank Gehry.
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.
