Top 10 Best Plastic Manufacturers in Shetland Islands

Plastics in the Shetland Economy

The Shetland Islands have a marine-based economy, so it is no surprise that plastic products are essential to daily operations. Insulated fish tubs keep catches fresh from boat to market. High-density polyethylene pens hold farmed salmon in sheltered voes. Durable plastic pipes carry water and drainage to remote crofts, and septic tanks serve properties far from mains sewerage.

Most large-scale plastic manufacturing takes place outside the islands, but Shetland is an important and demanding market for specialist plastic products. Island businesses also take plastic waste seriously, given how closely their livelihoods depend on clean seas. This guide highlights ten plastic manufacturers whose products are widely used across Shetland.

How These Manufacturers Were Selected

We considered how widely each company's products are used in Shetland's key industries, product durability in marine conditions, sustainability initiatives and recycling programmes, and the reliability of supply to the islands.

The Top 10 Plastic Manufacturers in Shetland Islands

1. Sæplast

Sæplast is a leading producer of insulated polyethylene tubs and containers for the fishing and seafood industries. Its durable, hygienic tubs are widely used by Shetland's fishing fleet and processors to keep catches chilled and in top condition.

2. ScaleAQ

ScaleAQ manufactures high-density polyethylene fish farm pens, moorings and related aquaculture equipment. Its robust plastic structures are designed to withstand exposed North Atlantic conditions and are used at salmon farms throughout the Northern Isles.

3. AKVA group

AKVA group supplies plastic cage systems, feed barges and technology for the aquaculture industry. Its pens and integrated systems help Shetland salmon producers improve fish welfare, feeding efficiency and site safety.

4. Fusion Marine

Fusion Marine is a Scottish manufacturer of plastic pens, workboats and aquaculture equipment. Its strong Scottish presence and practical designs make it a trusted supplier for fish farms operating in island waters.

5. Polypipe

Polypipe produces plastic piping systems for drainage, water management, plumbing and heating. Its products are used extensively in Shetland construction, from new housing developments to road drainage schemes.

6. Wavin

Wavin manufactures plastic pipe systems for water supply, sewerage and underfloor heating. Its durable, corrosion-resistant pipes are well suited to the wet, coastal conditions found across the islands.

7. Radius Systems

Radius Systems produces polyethylene pipes and fittings for water and gas networks. Its products support utility infrastructure and private water supplies, which are common in rural Shetland.

8. Kingspan Klargester

Kingspan Klargester is known for its plastic septic tanks, sewage treatment plants and rainwater harvesting systems. Many Shetland properties are not connected to mains sewerage, so these systems are essential for crofts, new builds and holiday homes.

9. Berry Global

Berry Global is one of the largest plastic packaging manufacturers in the world. Its containers, films and packaging are used by food producers and retailers supplying the islands.

10. Schoeller Allibert

Schoeller Allibert manufactures reusable plastic crates, pallets and containers. Its returnable packaging solutions help Shetland seafood and food businesses reduce single-use packaging and move goods efficiently by sea.

Tackling Marine Plastic

Shetland has a strong community commitment to protecting its coastline. Annual beach-cleaning campaigns bring volunteers together to remove marine litter, much of which drifts from far beyond the islands. Island businesses increasingly favour durable, reusable and recyclable plastics, and aquaculture companies have improved recovery and recycling of old pens, ropes and equipment. Waste that cannot be recycled can be processed at the Energy Recovery Plant in Lerwick, where it generates heat for the district heating network.

Key Trends in the Sector

• Circular design: Manufacturers are designing products for easier recycling and longer service life.
• Recycled content: More pipes, crates and packaging now include recycled plastic.
• Aquaculture equipment recovery: End-of-life pens and ropes are increasingly collected and reprocessed.
• Reusable packaging: Returnable crates and tubs are replacing single-use alternatives in the seafood supply chain.
• Stronger regulation: Scottish and UK policies on plastic packaging are pushing businesses toward greener options.

Choosing a Plastic Products Supplier

When selecting plastic products for Shetland conditions, prioritise UV resistance, impact strength and suitability for marine environments. Ask suppliers about warranties, recycling take-back schemes and recycled content. For aquaculture and seafood businesses, food-safe certification and hygiene performance are essential.

Why Durability Matters More on an Island

For a Shetland business, a cracked fish tub, a failed pen collar or a burst water pipe is more than an inconvenience. Replacement parts often have to travel by freight ferry from Aberdeen, and bad weather can delay deliveries for days. That is why island buyers put long service life ahead of the lowest purchase price. Thicker wall sections, UV-stabilised polymers and proven performance in cold seawater all reduce the risk of failure. Over the lifetime of the product, a well-made item that lasts twice as long usually costs much less once shipping, downtime and disposal are taken into account. It also means less plastic waste for the islands to deal with.

Conclusion

Plastic products are deeply woven into the Shetland Islands' fishing, aquaculture and construction industries. The ten manufacturers on this list supply the tubs, pens, pipes and tanks that island businesses rely on every day, while increasingly supporting recycling and sustainable design. Choosing durable, responsibly made products helps Shetland stay productive while protecting the seas that sustain it.
