PURIFICATION TECHNOLOGIES

Our cutting-edge purification technology elevates recycled plastics to premium quality by efficiently removing contaminants such as inks, odors, heavy metals, NIAS, and phthalates. This process delivers pure, high-performance materials that meet the strictest standards for food contact, medical applications, and beyond — enabling true circularity without compromising performance or safety.

​Our proprietary purification process uses advanced extraction and separation techniques to selectively target and eliminate impurities while preserving the original polymer structure. Through precise, multi-stage treatment, inks are dissolved, odors volatilized, heavy metals extracted, and trace substances like NIAS and phthalates reduced to undetectable levels — resulting in recycled plastics of virgin-like quality.

RIPA develops purification technologies designed to remove or reduce critical barriers in recycled plastics — including inks, odour, aluminium residues, heavy metals, plasticizers and selected NIAS — depending on material type, process scope and verification results.

RIPA Engineering connects purification know-how with industrial process logic.

Many recycling challenges are not solved by one machine alone. The decisive question is often where, when and how a material stream has to be treated before it can be separated, purified, extruded or reused at higher value.
RIPA analyses material flows, existing process chains and technical bottlenecks. We identify where value is lost, which treatment steps may be missing and how sorting, washing, purification, separation and extrusion need to interact.

Purified recycled plastics offer superior material properties, reduced environmental footprint, and significant cost advantages over virgin resins. By eliminating harmful substances and restoring clarity, strength, and purity, our technology enables closed-loop recycling, supports sustainability goals, and helps customers achieve carbon reduction targets while maintaining product excellence.

We work closely with partners across the value chain — from waste collectors and brand owners to converters and research institutions — to develop tailored purification solutions. Through joint projects and shared expertise, we accelerate innovation, optimize material flows, and drive the transition to a sustainable, circular plastics economy.
