International Synergies NI Ltd

What International Synergies NI Ltd does

International Synergies NI Ltd is a UK-based industrial symbiosis consultancy and software operator, structured as a private limited company with a parent entity (International Synergies Limited) registered in England and Wales and a Northern Ireland operating subsidiary. The company employs fewer than 20 staff across offices in Birmingham and Belfast and operates the SYNERGie® resource reuse platform, launched in 2009, which hosts data on 100,000 resources from 30,000 organisations across 30 countries and 6 continents. Its proprietary ADVISOR reference library captures successful reuse solutions globally, and the firm owns the registered NISP® facilitated industrial symbiosis methodology.

The company's business model blends professional services with platform monetisation. Service offerings include industrial symbiosis facilitation using the NISP® model, net zero and Scope 3 emissions strategy, place-based decarbonisation planning, and capacity building training. The SYNERGie Direct platform, made available for mainstream use in the UK and Republic of Ireland in 2025, provides self-serve resource matching. Revenue is generated through consultancy engagements, strategic advisory work, and platform access, with two key free-to-client regional programmes funded by the UK Government: the Resource Matching Service for Northern Ireland (managed by Invest NI) and the West Midlands Resource Reuse Network (delivered on behalf of West Midlands Combined Authority). Customers span private sector industries including construction, manufacturing, food and drink, utilities, cast metal foundries, metal surface treatment, agriculture, and battery production, alongside public sector and government clients.

The firm differentiates through accumulated operational data and recognised methodology, claiming 42 million tonnes of CO2e savings facilitated in England alone. It participates in European standardisation through CEN Workshop Agreement CWA 17354 and leads the Horizon Europe RISERS project (2024-2027) on industrial symbiosis standardisation for energy-intensive sectors. The company is privately held with no disclosed external funding and no parent company, suggesting founder or management ownership.

• Anthesis Group: Global sustainability and environmental consultancy delivering net zero, circular economy, and resource efficiency advisory to private and public sector clients. Closely comparable services portfolio and customer base to International Synergies' consulting arm.
• Circulor: Supply chain traceability and circular materials software used in battery, EV, and industrial value chains. Comparable as a circular-economy software vendor helping industrial customers track and validate material reuse and Scope 3 outcomes.

Broad incumbents

• Bureau Veritas: Global testing, inspection, and certification company expanding into ESG and sustainability assurance. Comparable as a buyer of industrial sustainability services, though its core business is certification rather than facilitation.
• Carbon Trust: Advisory body helping businesses and governments decarbonise, with circular economy and resource efficiency practices. Comparable advisory services and public-sector engagement model, though broader in scope and mission.
• Ricardo plc: Sustainability, energy, and environmental consultancy serving industry and governments. Comparable in delivering decarbonisation strategy and resource-efficiency advisory, though within a much wider engineering and policy portfolio.
• Veolia: Major waste management and resource recovery operator with circular economy offerings for industrial clients. Comparable in monetising industrial by-product reuse at scale, but from an infrastructure-led model rather than a facilitation-and-software model.
• Suez: International waste, water, and resource management group serving industrial customers with circular economy solutions. Comparable customer base and resource-recovery value proposition, though delivered through owned treatment infrastructure rather than a neutral matching platform.
• ERM (Environmental Resources Management): Large global environmental, health, safety, and sustainability consultancy. Comparable service offering in net zero strategy, circular economy, and resource efficiency work, but operating across a much broader portfolio rather than specialising in industrial symbiosis.
