Scotland's first commercial wind farm recycled 99.9% of its decommissioned turbines

Built World

Repowered Hagshaw Hill now puts out five times more power from 14 turbines instead of 26

Yesterday: 99.9% recycling rate circulates widely

Overview

Updated 1 hour ago

ScottishPower says 99.9% of the materials from Scotland's first commercial wind farm were recycled or reused when it was decommissioned. The 26 turbines at Hagshaw Hill in South Lanarkshire, turning since 1995, came down in 2023 and were replaced by 14 larger machines.

An independent report by engineering firm Mott MacDonald found 79.5% of materials were recycled and 20.4% reused. Even the composite blades—historically wind's hardest waste problem—were shredded and granulated into construction polymer by Northern Ireland's Plaswire, which substitutes for concrete, timber, and virgin plastics.

Why it matters

If this recycling rate scales across the UK's aging wind fleet, blade waste stops being a reason to delay repowering or building new capacity.

Historical Context

3 moments from history that rhyme with this story — and how they unfolded.

2000

EU End-of-Life Vehicles Directive (2000)

European law required automakers to take back and recycle cars, mandating rising recovery rates and banning landfilling of shredder residue.

Then

Recycling rates climbed above 80% and a dedicated infrastructure of dismantlers and shredders emerged.

Now

The directive built a self-sustaining recycling industry for a complex product class.

Why this matters now

It shows how regulation, not just economics, can scale recycling for hard-to-process products—a potential parallel for wind blades.

2020

Casper, Wyoming blade landfill (2020)

Thousands of decommissioned turbine blades were buried in a landfill near Casper, Wyoming. Photos of the blade pit became the global symbol of wind's waste problem.

Then

The images fueled criticism that wind turbines cannot be recycled.

Now

The attention pushed manufacturers to announce blade-recycling goals and researchers to develop composite-recovery methods.

Why this matters now

Hagshaw Hill offers a working counterexample: a full farm decommissioned with blades converted into construction polymer, not buried.

2023

Ørsted-Plaswire blade recycling pilot (2023)

Danish offshore wind giant Ørsted piloted Plaswire's process, cleaning, shredding, and granulating blades into RX Polymer for construction products.

Then

The pilot validated the polymer route and led to commercial contracts, including Hagshaw Hill.

Now

It established a template for blade recycling that other farm operators could adopt in repowering.

Why this matters now

Hagshaw Hill is the first full-farm application of the process Ørsted helped prove out.
