Large companies may do their own compounding prior to production, but some producers have it done by a third party. Companies that specialize in this work are known as Compounders. </p><p>The compounding of thermosetting plastic is relatively straightforward; as it remains liquid until it is <a href="/wiki/Curing_(chemistry)" title="Curing (chemistry)">cured</a> into its final form. For thermosoftening materials, which are used to make the majority of products, it is necessary to melt the plastic in order to mix-in the additives. This involves heating it to anywhere between 150–320 °C (300–610 °F). Molten plastic is viscous and exhibits <a href="/wiki/Laminar_flow" title="Laminar flow">laminar flow</a>, leading to poor mixing. Compounding is therefore done using extrusion equipment, which is able to supply the necessary heat and mixing to give a properly dispersed product. </p><p>The concentrations of most additives are usually quite low, however high levels can be added to create <a href="/wiki/Masterbatch" title="Masterbatch">Masterbatch</a> products. The additives in these are concentrated but still properly dispersed in the host resin. Masterbatch granules can be mixed with cheaper bulk polymer and will release their additives during processing to give a <a href="/wiki/Homogeneous" class="mw-redirect" title="Homogeneous">homogeneous</a> final product.

Plastic fragmentation into microplastics and nanoplastics can allow chemical additives to move in the environment far from the point of use. Once released, some additives and derivatives may persist in the environment and bioaccumulate in organisms. They can have adverse effects on human health and biota. A recent review by the United States Environmental Protection Agency (US EPA) revealed that out of 3,377 chemicals potentially associated with plastic packaging and 906 likely associated with it, 68 were ranked by ECHA as "highest for human health hazards" and 68 as "highest for environmental hazards".<sup id="cite_ref-:0_2-12" class="reference"><a href="#cite_note-:0-2"><span class="cite-bracket">[</span>2<span class="cite-bracket">]</span></a></sup> </p> <div class="mw-heading mw-heading3"><h3 id="Recycling">Recycling</h3></div> <link rel="mw-deduplicated-inline-style" href="mw-data:TemplateStyles:r1236090951"><div role="note" class="hatnote navigation-not-searchable">Main article: <a href="/wiki/Plastic_recycling" title="Plastic recycling">Plastic recycling</a></div> <p>As additives change the properties of plastics they have to be considered during recycling. Presently, almost all recycling is performed by simply remelting and reforming used plastic into new items. Additives present risks in recycled products, as they are difficult to remove. When plastic products are recycled, it is highly likely that the additives will be integrated into the new products. Waste plastic, even if it is all of the same polymer type, will contain varying types and amounts of additives. Mixing these together can give a material with inconsistent properties, which can be unappealing to industry. For example, mixing different colored plastics with different <a href="/wiki/Plastic_colorant" title="Plastic colorant">plastic colorants</a> together can produce a discolored or brown material and for this reason plastic is usually sorted by both polymer type and color before recycling.<sup id="cite_ref-:0_2-13" class="reference"><a href="#cite_note-:0-2"><span class="cite-bracket">[</span>2<span class="cite-bracket">]</span></a></sup> </p><p>Absence of transparency and reporting across the value chain often results in lack of knowledge concerning the chemical profile of the final products.

A recent study found brominated dioxins as unintentional contaminants in toys made from recycled plastic <a href="/wiki/Electronic_waste" title="Electronic waste">electronic waste</a> that contained brominated flame retardants.
