Our Mission

Turning Waste into Value

At BiOrbic, we see waste not as an endpoint, but as a starting point for innovation. This pillar focuses on transforming society’s waste streams, like food, plastic, and carbon dioxide, into valuable new resources. By developing circular systems and cutting-edge technologies, we aim to reduce waste, lower emissions, and recover materials that would otherwise be lost.

Our mission is to help Ireland and Europe lead the transition to a circular bioeconomy, where waste becomes feedstock for new products, energy, and materials.

What Research is BiOrbic Doing?

The Valorisation of Waste Resources pillar targets three key waste challenges: food waste, plastic waste, and CO₂. Each area focuses on prevention, recycling, or conversion—building efficient, circular systems that retain value within the economy.

Valorisation of Waste Resources

Green Chemistry for the Bioeconomy

This challenge explores how captured CO₂ can become a valuable resource. Researchers are developing green technologies to convert waste CO₂ from biological and industrial processes into useful products like fuels, polymers, and feed. By turning emissions into materials, this work supports a carbon-neutral circular economy.

key research areas

Capture and separate CO₂ using advanced membrane and catalytic technologies.

Convert biogenic CO₂ into chemicals, polymers, and fuels.

Integrate life cycle analysis (LCA) to assess environmental and economic impacts of CO₂ reuse.

Porous 2D nano-photoreactive materials for carbon dioxide capture and photochemical conversion
For sustainable large-scale utilization of CO2, the commodity products of CO2 conversion processes should be economically viable and in high demand. However, there are a number of problems and limitations in existing approaches in the capture and conversion of CO2 into useful chemical products. This proposal aims to develop new layered double hydroxide (LDH) based systems for the capture and conversion of CO2 into useful chemicals such as formates and methanol.

Synthesis of CO2 based biodegradable polymers using novel catalyst systems and enhancing the properties of polymers by developing nanocomposites and blends.
Valorisation of Waste Resources

Food Waste

This challenge focuses on preventing food waste and turning unavoidable waste into valuable products. Researchers are finding new ways to reduce food losses across the supply chain, from farms to consumers, while creating renewable energy, biobased fertilisers, and chemicals from leftover materials.

key research areas

Cut food waste by 25% via prevention and innovation.

Turn leftover food into biogas, fertilisers, and biochemicals.

Boost food system circularity with data and community action.

SHARING SOLUTIONS: Identifying, valorising and optimising food waste prevention and reduction via Food Sharing Initiatives (FSIs)
This project will establish and analyse the actual and potential sustainability (i.e. social, economic and environmental) impacts of ICT-mediated food sharing initiatives (FSIs), which include community growing, cooking, eating and surplus food redistribution activities, for waste prevention and reduction in Ireland in order to develop appropriate policy supports to meet SDG Target 12.3: to halve global food waste at the retail and consumer levels and reduce food losses, including postharvest losses, along supply chains by 2030. The PhD student will gain important transdisciplinary and team work skills throughout the project, refining and applying the SHARING SOLUTIONS approach alongside the existing SHARING SOLUTIONS team, developing novel metrics for aggregating sustainability impacts and engaging with FSIs, city and county council officers, food supply actors and researchers to establish impacts and provide policy and practical recommendations.

Valorisation of Waste Resources

Plastics

This challenge aims to transform how we produce, use, and reuse plastics. BiOrbic researchers are developing new biobased, compostable, and recyclable plastics, while finding innovative ways to break down and repurpose mixed plastic waste. The goal is to reduce pollution, cut carbon emissions, and recover valuable materials from what we currently throw away.

key research areas

Develop biodegradable plastics with a 50% lower carbon footprint.

Increase plastic recycling and re-circulation to 55% by 2030.

Create technologies to turn mixed plastic waste into new materials.

Why This Research Matters

Every waste stream is a lost opportunity. Our research captures that lost value, cutting pollution, supporting new green industries, and strengthening resource independence.

Close the Loop

Keep materials in use through recycling, bioconversion, and reuse.

Reduce Emissions

Lower GHGs from food, plastics, and industrial waste.

Create Circular Value

Turn waste into energy, materials, and products that support local economies.

Innovate Sustainably

Develop scalable technologies that can be adopted by industries across Ireland and Europe.

Strategic Alignment

Aligned with Key EU and National Targets

This pillar supports Ireland’s transition to a circular, low-emission economy in line with major EU and national objectives.
