Recycled Marine Plastic HDPE Granulate

Source your recycled plastic feedstock directly from the ocean. Odyssey Innovation is a UK supplier of bulk recycled marine plastic HDPE granulate, produced from post-consumer plastic recovered through our Marine Regeneration Scheme and Net Regeneration Scheme — giving waste plastic a second life as a verified industrial raw material.

Every kilogram of granulate you purchase directly supports our Paddle for Plastic campaign, driving behavioural change in coastal and fishing communities and keeping plastic out of our oceans.

Available in 20kg bags (MOQ) or 1 tonne bulk bags, across five colour grades. Custom quantities and colour grades available on request. Technical data sheets available on request.

Available Colour Grades:

• Black — highly consistent colour
• Grey — highly consistent colour; ideal for applications requiring dyeing or pigmentation
• White — highly consistent colour
• Neon — highly consistent colour
• Mixed Marine — a blend of similarly coloured recovered material; shades may vary batch to batch. Any surface marking (e.g. ink) will disappear during melting and processing.

All material is inspected and processed to remove contaminants. HDPE produces no dangerous fumes during melting when processed within recommended temperature ranges. If you require a specific shade or purity level, please contact us — we can often accommodate custom requirements.

Frequently Asked Questions

What is recycled marine plastic HDPE granulate?
Marine plastic HDPE granulate is post-consumer high-density polyethylene recovered from UK coastlines and the Mediterranean through our Marine Regeneration and Net Regeneration Schemes, cleaned, processed, and converted into pellets or regrind suitable for use as a raw material in manufacturing.

Can it be used for injection moulding?
Yes — recycled HDPE granulate is well-suited to injection moulding. We recommend requesting a data sheet and conducting trials prior to full production runs.

Can it be used for extrusion?
Yes — extrusion is one of the primary processing routes for recycled HDPE granulate, used in pipe, profile, and sheet manufacturing.

Is grey granulate suitable for dyeing?
Yes — grey is the most versatile colour grade for applications requiring pigmentation or dyeing, as it provides a neutral base that accepts colour more readily than darker grades.

How consistent is the colour?
Black, Grey, White, and Neon grades are highly consistent. The Mixed Marine grade is a blend of similarly coloured recovered material and shades may vary between batches. Any surface marking such as ink will disappear during melting and processing. If you need a specific shade or purity level, please contact us.

Are there any fumes during processing?
HDPE produces no dangerous fumes during melting when processed within recommended temperature ranges. Data sheets with full processing guidance are available on request.

Do you provide data sheets and sustainability documentation?
Yes. Technical data sheets are available on request, along with chain-of-custody documentation and impact data to support your sustainability reporting or product marketing claims.
