Iceland Foods’ Solar Project and Deliveroo’s Sustainable Packaging Challenge

Major food retailers turn to solar power and packaging innovation

Two UK food businesses have announced significant sustainability projects this month. Iceland Foods is installing extensive solar capacity across its distribution network. Meanwhile, Deliveroo has launched a university partnership to redesign takeaway packaging and remove plastic linings from food containers.

Both initiatives address different aspects of commercial sustainability. One tackles energy costs and carbon reduction through infrastructure. The other focuses on waste reduction and material innovation. For businesses watching regulatory pressure increase around emissions reporting and plastic reduction, these projects offer practical examples of how large operators are responding.

The scale of Iceland’s solar rollout is notable. The company operates across multiple sites and handles substantial refrigeration loads. Deliveroo’s approach targets a different problem: the packaging waste generated by thousands of restaurant partners. Each project reflects the specific operational challenges facing these businesses.

Iceland Foods expands solar capacity across distribution centres

Iceland Foods is working with Ortus Energy and SSE Energy Solutions to install solar systems at six distribution centres. The project uses a Power Purchase Agreement structure, which locks in renewable energy pricing over a fixed contract period. Two sites are already operational.

Each system includes over 1,200 solar panels with a combined capacity of 608 kilowatts peak per location. According to Iceland, the energy produced at two centres would be sufficient to power an average Iceland store for almost six years. The company is also pursuing a separate 10 megawatt rooftop solar rollout with Shawton Energy Partners.

This builds on existing renewable energy arrangements. Iceland already sources 14% of its annual electricity from an off-site solar farm through another Power Purchase Agreement. The retailer plans to install solar panels at 96 additional sites by March 2026. Currently, 20 sites have rooftop solar arrays that generated 3 gigawatt hours during the 2025 financial year.

Iceland Foods uses 100% renewable electricity for its grid supply. The company has also reduced Scope 3 emissions by approximately 2,100 tonnes of carbon dioxide equivalent through its Green Mile logistics programme. That initiative focuses on route optimisation and vehicle efficiency across the distribution network.

Deliveroo partners with university students on packaging redesign

Deliveroo has relaunched its Sustainable Packaging Challenge for 2026, working with Pho Restaurant and Sheffield Hallam University. Students are tasked with redesigning two specific packaging items: containers for fresh herbs and chillies, plus a separate rice and curry container. The goal is to reduce plastic content while maintaining food quality during delivery.

This continues work from previous years. The 2024 challenge focused on cup design. In 2025, the winning entry replaced plastic-lined takeaway boxes with an industrially compostable alternative. That design uses PLA-lined paperboard instead of fossil fuel-based plastic lining. PLA stands for polylactic acid, a plant-based material. The new boxes can be disposed of with food waste in industrial composting facilities.

Winners receive £1,500 and the opportunity to bring their design to market through Deliveroo’s restaurant network. The company previously launched a £2.5 million packaging fund in 2022, offering a 50% subsidy to partners switching to home-compostable or recyclable packaging. Deliveroo estimates its restaurant partners generate over 400 tonnes of plastic packaging waste annually.

Commercial drivers behind infrastructure and material innovation

Both projects respond to mounting pressure on food businesses to demonstrate environmental progress. However, the commercial logic differs significantly between energy infrastructure and packaging innovation.

For Iceland Foods, solar installation addresses three business issues simultaneously. First, it reduces exposure to volatile energy markets. Power Purchase Agreements provide price certainty over multi-year periods, which matters when operating energy-intensive cold storage and refrigeration. Second, it supports carbon reporting requirements. Renewable electricity procurement reduces Scope 2 emissions directly. Third, it may strengthen positioning in tenders where environmental criteria carry weight.

Distribution centres represent ideal solar candidates. They offer large roof areas, consistent daytime energy demand, and long lease terms that justify capital investment. Nevertheless, the financial case depends on grid connection capacity, local network constraints, and subsidy availability through mechanisms like the Smart Export Guarantee.

Deliveroo’s packaging challenge operates differently. The company doesn’t manufacture or supply packaging directly. Instead, it relies on thousands of independent restaurant partners who make their own procurement decisions. The student competition creates new product options that restaurants can adopt, but uptake remains voluntary unless subsidised.

Material innovation in food packaging must balance multiple requirements. Containers need to withstand hot liquids, prevent leaks, maintain structural integrity during transport, and protect food safety. Industrial composting infrastructure remains patchy across UK local authorities. A compostable container only delivers environmental benefit if it reaches appropriate waste processing. Otherwise, it may end up in general waste or contaminate recycling streams.

Solar projects require grid capacity and long-term site control

Iceland’s rollout illustrates the practical requirements for commercial solar installation. Each site needs adequate roof structure to support panel weight and wind loading. Grid connection capacity must accommodate export during low-demand periods. Electrical infrastructure may need upgrades to handle variable supply.

Distribution centres typically operate 24 hours, but solar generation concentrates in daytime hours. This creates a mismatch between production and consumption. Battery storage could address this gap, but adds significant cost. Alternatively, businesses can export surplus generation to the grid under a Power Purchase Agreement or the Smart Export Guarantee scheme.

Planning permission is usually required for rooftop solar, though permitted development rights cover many commercial installations. Listed buildings or sites in conservation areas face additional restrictions. Some landlords include restrictive covenants in leases that prevent structural modifications without consent.

The financial case depends on electricity pricing, available subsidies, and capital costs. Solar panel prices have fallen substantially over the past decade. However, installation labour, scaffolding, electrical work, and grid connection charges still represent major cost components. Payback periods typically range from seven to 15 years for commercial installations.

Packaging innovation confronts infrastructure and behaviour gaps

Deliveroo’s challenge highlights persistent obstacles in takeaway packaging. PLA-lined containers offer a plant-based alternative to plastic-lined paperboard. Yet industrial composting facilities remain scarce. According to WRAP, fewer than half of UK councils collect food waste separately. Even fewer accept compostable packaging alongside food waste.

This creates confusion for consumers and restaurants alike. A container labelled industrially compostable may not be accepted by local waste services. If placed in recycling bins, it contaminates paper and cardboard streams. If sent to general waste, it offers no environmental advantage over conventional plastic-lined packaging.

Home composting presents different challenges. Most home compost heaps don’t reach the sustained temperatures required to break down PLA materials. Packaging marketed as home-compostable must meet specific standards, but consumer understanding remains low. Many people lack access to home composting facilities entirely.

Cost also affects adoption. Alternative materials typically cost more than conventional plastic-lined options. Deliveroo’s 50% subsidy addresses this barrier, but only for participating restaurants. Smaller independents may lack awareness of the scheme or find the application process burdensome. Larger chains often negotiate packaging contracts centrally, which can delay switching to new materials.

What UK food businesses should consider for energy and packaging

These projects offer useful reference points for businesses evaluating their own sustainability priorities. Energy and packaging represent two areas where regulatory scrutiny continues to increase, particularly for companies reporting emissions or bidding for public sector contracts.

Solar installation makes most sense for businesses with suitable property and long-term site control. Freehold ownership or leases extending beyond ten years provide the stability needed to justify capital investment. Businesses should assess roof condition, structural capacity, and grid connection availability before committing to feasibility studies. Distribution centres, warehouses, and manufacturing facilities often present better opportunities than high street retail units.

Power Purchase Agreements offer an alternative for businesses without suitable property. These contracts allow companies to procure renewable electricity from off-site generation, often at predictable pricing over multi-year terms. However, contract terms vary significantly. Businesses should scrutinise pricing mechanisms, volume commitments, and termination clauses carefully. Some agreements include complex indexation formulas that reduce price certainty.

For packaging decisions, businesses need to understand local waste infrastructure before switching materials. Industrial composting capacity remains limited across much of the UK. A compostable container only delivers environmental benefit if it reaches appropriate processing. Otherwise, the switch may increase costs without reducing environmental impact. WRAP provides useful guidance on packaging choices and local authority waste acceptance.

Customer communication matters as well. Clear labelling helps consumers dispose of packaging correctly. However, many businesses underestimate the complexity of waste messaging. Terms like biodegradable, compostable, and recyclable carry specific meanings that consumers often misunderstand. Packaging that combines multiple materials can confuse disposal further. Simple instructions at point of use improve compliance.

We support businesses with carbon reporting and net zero programme development, including energy procurement strategy and supply chain emissions reduction. For companies facing packaging decisions, understanding material lifecycle impacts and waste infrastructure gaps forms part of comprehensive environmental assessment. The SBS Academy offers training on Scope 3 emissions categories, which include both purchased energy and waste generated in operations.

Government guidance and industry resources on energy and packaging

Businesses considering solar installation should consult the Department for Energy Security and Net Zero guidance on solar photovoltaic systems. This covers planning requirements, grid connections, and available support schemes. The Smart Export Guarantee scheme details from Ofgem explain how businesses can earn payments for exporting surplus solar generation to the grid.

For packaging decisions, WRAP’s recyclability guidelines for food and drink packaging provide detailed technical specifications. The Environment Agency guidance on packaging waste obligations explains extended producer responsibility requirements that apply to many food businesses. These regulations affect businesses that handle or import specified packaging quantities.

The Energy Technology List maintained by the Department for Energy Security and Net Zero identifies energy-efficient equipment eligible for Enhanced Capital Allowances. This tax relief can improve the financial case for solar installation and other energy efficiency investments.
