Recycling Process Optimisation, Audits & Plant Design

Specialist Engineering Expertise for Sustainable Polymer Projects

Nextek provides specialist expertise in optimising plastic recycling processes and designing plants that convert post-consumer PET and HDPE bottles and PP pots trays and tubs into high-quality recycled materials for food contact applications, high-value materials for non-food packaging and industrial applications.

We identify and develop cost-effective processing technologies that enable recycled polymers to replace virgin resin, typically at 30–50% recycled content and, in some applications, up to 100%.

Technical, Process & Financial Audits

We conduct technical, process and financial audits of existing and proposed recycling operations, assessing feedstock, processing technology, product quality, market conditions, productivity and commercial viability.

  • Independent assessments providing the insights needed to identify clear investment opportunities.
  • Robust operational diagnostic strategies deployed to actively reduce technology investment risk.
  • Data-driven performance benchmarks formulated to optimize material throughput performance.

Process Optimisation & Feedstock Management

A core Nextek capability is developing cost-effective processing improvements for existing process technologies that can accommodate the inherent variability of recycled feedstocks while consistently achieving the required product specifications.

  • Engineering improvements custom-tailored to accommodate raw scrap material stream variations.
  • Stabilized manufacturing mechanics ensuring products consistently meet strict client technical specifications.
  • System tuning engineered to maximize performance metrics inside existing operational infrastructure.

Plant Projects & Project Management

We work with recyclers, brand owners, equipment suppliers and principal contractors on both greenfield and brownfield plant projects, from concept and process design through commissioning.

  • Seamlessly integrates capacity and process optimization across all operational building blocks.
  • Bespoke technical equipment selection balancing throughput goals with target capital spending budgets.
  • Robust quality assurance and quality control systems integrated to deliver reliable, scalable and productive operations.

Global Implementation Infrastructure

Nextek has extensive international experience in developing sustainable polymer recycling projects and recycled-material specifications across several distinct economic operational sectors.

  • Proven execution track record working across the UK, Europe, Middle East, and Latin America.
  • Specialized project deployments successfully introduced across Southeast Asia and Australia.
  • Action-ready regional roadmaps helping our clients develop circular economy and closed-loop solutions.

Machinery & Equipment Advisory

Nextek provides independent technical and commercial advice on recycling machinery, equipment and processing technologies, helping clients select the right solutions for their materials, products and investment objectives.

We deliver feasibility studies, process technology assessments and project development programmes for SMEs through to multinational corporations and governments, drawing on extensive experience across the recycling, packaging and polymer industries.

Our expertise covers the full project lifecycle – from technology evaluation, process design and equipment selection to capital planning, commissioning and commercial implementation. We represent our clients when they are working with contractors and suppliers, to ensure designs and operation are practical, maintainable, productive and cost effective taking into consideration the materials and products and the operation conditions.
