Plant manufacture plastics

Plastics are derived from natural, organic materials such as cellulose, coal, natural gas, salt and, of course, crude oil. Crude oil is a complex mixture of thousands of compounds and needs to be processed before it can be used. The production of plastics begins with the distillation of crude oil in an oil refinery. This separates the heavy crude oil into groups of lighter components, called fractions. Each fraction is a mixture of hydrocarbon chains chemical compounds made up of carbon and hydrogen , which differ in terms of the size and structure of their molecules.

In a world deluged by plastics, a giant factory rises to manufacture more

VIDEO ON THE TOPIC: Plastics Manufacturing: From Idea to Product

The main material used in plant engineering is stainless steel. The variant L is regarded as standard; material incompatibilities of steel with the product play almost no role. This is different for plastics. Beside the leach-out, ageing and surface finishing, other quality features are often specified. Now, what are the general requirements for plastics in pharmaceutical plant engineering? There is no simple answer to this question. The GMP regulations partially exclude this topic - there is no " gold standard " either.

The requirements always depend on the concrete application purpose. Three types of plastics are used: soft plastics e. The essential quality features are surface finishing and material compatibility. One GMP requirement for pharmaceutical plants is that they must be easy to clean. Therefore, the surfaces in contact with products must be smooth.

This value is measured in some parts of the plant during qualification or documented by certificates from the plant manufacturer. It is more difficult to determine the surface of plastics. Indeed, mechanical detectors pose a great risk of scratching the plastic surface. When specifying average roughness values for plastic parts, manufacturers often use statistical methods, i.

In the case of thermoplastics, which are produced by means of injection moulding and for which the manufacturers use highly polished injection moulds, the high surface quality is generally ensured by the manufacturing process. This is also confirmed in material certificates and can be regarded as sufficient if the supplier's quality system is trusted.

The SEMI F57 standard for the semiconductor industry ultrapure media technology deals with the surface of plastic components. However, there is no such comparable specification within the pharmaceutical world. It is much more difficult to make a statement about material compatibility.

A certificate of food suitability is often used as a proof - i. Certificates with the following reference serve this purpose:. However, it may also be useful to provide specifications for compliance with further requirements:.

The US Pharmacopoeia also makes statements on the pharmaceutical suitability of plastics and divides them into six biocompatibility classes. USP Class VI represents the strictest class and is equivalent to a pharmaceutical authorisation for polymer materials.

In order for a material to receive a Class VI classification, tests are specified which must be performed in external test laboratories. For this purpose, animal testing shall be carried out to determine acute toxicity irritation when swallowed or inhaled , intra-cutaneous reactivity tissue test or an implantation test.

This requirement is often unnecessarily specified. It is important to be aware that not only money is wasted, but also unnecessary animal testing is indirectly caused. In biotechnological production, it can also be useful to specify "ADI free". The pharmaceutical manufacturer himself must clarify whether the plastic used is chemically not reacting or interacting with the pharmaceutical material.

Furthermore, the leach-out of plastic materials is critical in biotechnology, i. In leachable studies, the pharmaceutical material is used to check which substances actually leach out under real conditions. The results of the studies must then be evaluated toxicologically, taking into account the process, product, application, etc. The results of the studies must then be evaluated toxicologically. According to the applicable GMP specifications e. EU GMP Annex 15 , verification of the construction materials must be carried out during qualification.

The reason for this is to ensure that the plant was built from the materials required by the pharmaceutical manufacturer the material of the plant must not have any negative influence on the product. Since not every pharmaceutical manufacturer has the necessary means for material testing or identification, the material certificates come into play:.

The study also found that in , only nine percent of plastics have been recycled, 12 percent incinerated and 79 percent accumulated in landfills or the ocean. If this trend continues, it is expected that roughly 12, Mt of plastic waste will be in landfills or the natural environment by The global plastic industry today is considering alternatives, especially the use of more sustainable materials like bioplastic which is a plant-based alternative made from renewable materials like starch from corn, potato, soy protein, cellulose and lactic acid.

For productive cycles you need smooth running loops. EREMA makes plastics recycling efficient and profitable. Highest productivity and flexibility, low energy consumption, easiest operation. That is what makes our plastics recycling machines stand out. For everything within a system to be fully integrated, it needs people who share the same values.

General requirements for Plastics in Pharmaceutical Engineering

Many in the Pittsburgh area see it as an economic engine, but others worry about the long-term harm. Photograph: The New York Times. The acre property looks like a giant Lego set rising from the banks of the Ohio River. It is one of the largest active construction projects in the United States , employing more than 5, people. When completed, the facility will be fed by pipelines stretching hundreds of miles across Appalachia. It will have its own rail system with 3, freight cars. And it will produce annually more than 1 million tons of something that many people argue the world needs less of: plastic.

Plastics Manufacturing Plants

Now, this little land is in focus for all the wrong reasons. Studies have found a manufacturing site here to be continuously leaking out plastic pellets in the millions, polluting and damaging the environment at a massive scale. Researchers from the Gothenburg University who conducted the studies were shocked at these findings. And this, despite the many regulatory systems, both national and international, already in place to prevent the same. The manufacturing site in Stenungsund ships the plastic pellets to plants located around the world. These pellets, considerably small in size, is the primary raw material used by various plants to produce all kinds of plastic products. Plastic pellets have long been known to be damaging to the environment, especially the marine ecosystem where they usually end up. In fact, this problem has been brought into focus since the s, with the USA proposing legislation to control the same in The leakage from Stenungsund, however, does not stay in Stenungsund.
