Casualty overcomes milestones for sustainability targets

Sustainability has been a huge priority on board the set of Casualty in 2025, with huge strides made to meet sustainability targets across energy, transport, waste disposal and water use.

Casualty is the second Wales-based production to introduce a Solar Hybrid Generator, which alternates between using solar energy and fuel made from waste fats and vegetable oils (HVO) to power on set activity whilst on location.

The long-running drama has also marked itself as a no-plastic production, ensuring that cast and crew eat and drink from reusable mugs and compostable cups on set. By utilising compostable vegware for food and drink, it was possible for the production to redirect 55% of their waste to anaerobic digestion, meaning the organic waste can be converted into renewable energy and fertiliser.

BBC Roath Lock Studios, where the show is primarily filmed, has a Carbon Trust Standard for zero waste to landfill and uses 100% mixed renewable energy across the building. Alongside these efforts, each department worked together to reuse resources such as paints, props, costumes, storage containers, medical equipment, ink cartridges and soft plastics, whilst adopting a three-bin recycling set up located across the studios and offices of Casualty.

After surveying the quality of plumbing and water waste at BBC Roath Lock Studios, the sustainability team were able to add aerators, fix toilets and improve shower facilities across the studio area to save money and to be more efficient. Within 6 weeks they’ve managed to save 4746 litres of water a day!

With 2026 just around the corner, the team look forward to seeing how our new green policies can take further effect and discuss how they can work together on making Casualty an even more sustainable production.
