Manufacturing from regrind allows for the reutilization of plastics. Moreover, it is a way to reduce production costs for many products. You can read about which industries benefit from it, as well as the advantages and disadvantages of this eco-friendly material in this article. <\/strong><\/p>\n\n

Can plastics be used more than once?<\/strong> This question is particularly relevant if a company’s mission is to care for the environment, as the production of plastic often involves non-environmentally friendly methods. One solution to this problem in many cases is regrind. <\/p>\n\n

What is regrind?<\/h2>\n\n

Regrind is produced in the process of recycling plastics. By using plastic waste, it is a cost-effective way to obtain material with properties very similar to traditional granules, making it suitable for various industries. <\/p>\n\n

Advantages of using regrind<\/h2>\n\n

Ecology<\/h3>\n\n

First and foremost, the use of regrind in the production of plastic products is environmentally friendly. It allows for the utilization of plastic waste, which, through the recycling process, attains suitable parameters for reuse. <\/p>\n\n

Reduction of production costs<\/h3>\n\n

Regrind obtained through the recycling of plastics is cheaper than the original material, with potential savings of up to 20%.<\/strong><\/p>\n\n

Properties similar to the primary material<\/h3>\n\n

The material obtained in this way has properties similar to the original material. Slight differences may be due to the presence of minor remnants from the previous product, which has a minimal impact on the parameters of the final product. <\/p>\n\n

Various forms of regrind<\/h3>\n\n

Similar to traditional granules, regrind is typically available in the form of pellets or filaments. This makes it easy to use in injection molding or extrusion processes. The exception is projects carried out using thermoforming technology, where regrind takes the form of sheets, and rotational molding, where it is in the form of powder pigmented with carbon black to minimize visibility of imperfections. <\/p>\n\n

Resistance to environmental conditions<\/h3>\n\n

Regrind is resistant to the effects of harmful environmental factors, such as moisture and temperature fluctuations.<\/p>\n\n

Strength and lightweight<\/h3>\n\n

Regrind is characterized by its high strength, making it a durable and resistant solution to mechanical damage, while also being lightweight. This makes it easy to transport even over significant distances. <\/p>\n\n

Disadvantages of using regrind<\/h2>\n\n

Thorough cleaning of waste<\/h3>\n\n

Regrind requires thorough cleaning before it goes through the entire recycling process. Regrinding can leave, for example, metal shavings. Because of this, the material may have a slightly different melting temperature, hardness, and altered other parameters. <\/p>\n\n

Limited applicability in smaller products<\/h3>\n\n

It is not recommended to use regrind for the production of parts that should have a high surface aesthetic.<\/p>\n\n

Lower durability in the most demanding conditions<\/h3>\n\n

Material used in very demanding operating conditions should be made from virgin plastic and not from recycled sources.<\/p>\n\t\t

Applications of regrind<\/h2>\n\n

Regrind is used in the production of covers for the heating industry<\/strong>, where ABS regrind is utilized. This material can be used to manufacture covers that are less complex and do not need to meet highly specific functional requirements. We discuss more about the use of plastics in the heating industry in a dedicated article.<\/a><\/p>\n\n

Producers of packaging in the food industry also utilize regrind<\/strong>. Although regrinds cannot be used for direct contact with food, they can be employed in the layers of packaging that do not come into direct contact with the food. In such cases, traditional plastics like PET are used in the outer layer of the packaging, constituting 20% of the product’s volume. The remaining portion consists of a mixture of recycled PET, PE, and PET MIX. This directly translates to a lower cost, and such cost optimization does not negatively affect the properties of the end products. <\/p>\n\n
