Gali Feldboy-Klinger, Global Sustainability Director at UBQ Materials and Dan Jarvis, Product Group Manager for Performance Polymers – Specialties, Plastribution, discuss the challenges and opportunities circularity presents for the renewable materials sector.

Navigating the transition to a circular economy within the renewables sector is steeped in challenges ranging from feedstock dilemmas to production efficiency and regulatory hurdles, but new innovations in waste-to-materials technologies may provide a path forward.

The imperative to transition towards sustainable practices has never been more pressing. Central to this shift is the concept of a circular economy, where resources are used and reused efficiently, minimising waste and environmental impact.

While the path towards the circular transition in the renewable materials sector is complex and filled with hurdles, there are promising solutions already available to overcome these challenges.

Innovation and the feedstock dilemma


Feedstock choice is one of the core challenges facing the renewable materials sector. The utilisation of first-generation bio-based feedstock derived from food crops raises ethical concerns due to deforestation and competition with food and water resources, while second-generation bio-based feedstock derived from agricultural waste presents challenges related to processing requirements.

However, innovations in feedstock utilisation can play a critical role in overcoming these challenges. Research and development efforts focused on harnessing third-generation feedstock, such as municipal solid waste, can unlock new opportunities for sustainable material production.

By investing in innovative technologies for waste-to-material conversion, we can mitigate the environmental impacts of materials—reducing reliance on both fossil and resource-intensive bio-based resources—while addressing urban waste challenges and maximising resource efficiency.

Scaling production efficiency and technological advancements

Efficiently scaling production to meet the growing demand for sustainable materials, while managing costs, is a significant hurdle.

Transitioning to sourcing sustainable materials also poses a challenge for companies striving to balance environmental responsibility with financial viability.

As such, finding solutions that integrate seamlessly with existing infrastructures can ensure a smooth transition.

Cost considerations are significant for novel sustainable materials, but long-term cost stability should be prioritised over immediate savings, especially given the evolving landscape of renewable materials. 

By investing in research and development, we can optimise conversion technologies and production processes to enhance efficiency and scalability within the renewable materials sector.

This commitment improves existing methodologies and fuels advancements in recycling technologies, biorefining processes and material engineering.

These innovations form a crucial part of a holistic sustainable materials strategy, integrating both recycled and novel materials seamlessly.

Through these efforts, we can rapidly integrate sustainable materials that match or even surpass the performance and cost-effectiveness of their conventional counterparts, leveraging the power of innovation to drive tangible change.

Regulatory landscape and the collaborative ecosystem


Navigating the regulatory landscape poses a dual challenge. While regulations aimed at driving demand for sustainable materials are essential for fostering market growth, they can inadvertently create barriers by targeting traditional fossil fuel-based products.

For instance, in 2021, the EU implemented restrictions on certain single-use plastics to promote sustainability. While these measures are intended to reduce plastic pollution, they can inadvertently create barriers for traditional plastic manufacturers.

These regulations also drive innovation in sustainable alternatives such as biodegradable plastics, plant-based materials, or reusable alternatives like metal straws or cloth bags. 

Harmonising regulations across regions and ensuring adherence to international quality norms presents a formidable task for industry stakeholders. Collaborating with regulators to develop coherent and supportive policies is critical for overcoming regulatory challenges.

By advocating for regulations that incentivise sustainable practices and provide a level playing field for renewable materials, industry stakeholders can create an enabling environment for market growth.

Establishing collaborative ecosystems among industry players is crucial for driving innovation and resilience in the renewable materials sector.

Collaboration encompasses partnerships with both upstream and downstream stakeholders, including compounders at the beginning of the supply chain and product manufacturers later in the production process.

It also involves waste providers and communities striving for a sustainable waste management solution.

However, fostering meaningful partnerships requires overcoming competitive barriers and aligning diverse interests towards common sustainability goals. Developing a strong bond with customers facilitates the effective alignment of supply and demand.

For example, two prominent figures in the industry—a material compounder and a manufacturer—can join forces to craft an eco-conscious material or product derived from unsorted household waste.

By engaging end-customers in the development phase, they can both distinguish their products while aptly synchronising supply with demand in response to the increasing consumer preference for sustainable products.

The role of policy in advancing novel sustainable materials


Policy innovation and collaboration are essential for building a regulatory environment that supports the transition towards a circular economy.

Governments, industry stakeholders, and non-governmental organisations are already working together to develop and implement policies that incentivise sustainable practices, discourage waste generation, and promote circularity. 

For instance, the European Commission’s Circular Economy Action Plan (CEAP) delineates various objectives targeting both consumers and industries.

These encompass initiatives aimed at mainstreaming sustainable products in the EU, empowering consumers and public buyers, and prioritising sectors with high resource usage and significant potential for circularity, such as batteries, vehicles, packaging, plastics, textiles, construction, buildings, food, water, and nutrients.

This strategy aims to implement waste reduction practices and promote circular systems across these sectors. By fostering dialogue and collaboration among key stakeholders, we can overcome regulatory barriers and accelerate the adoption of sustainable materials on a global scale.

Consumer awareness and demand

Despite growing consumer awareness of environmental issues, translating this awareness into real demand for products made with sustainable materials remains a challenge.

Educating consumers about the benefits of renewable materials and incentivising sustainable consumption habits is essential for driving market demand and encouraging widespread adoption.

Engaging consumers through education and awareness campaigns is vital for fostering demand for sustainable materials.

Investing in sustainable infrastructure

Investment in long-term and financially viable sustainable infrastructure and systems which reduce environmental impacts, resource consumption, and greenhouse gas emissions will support the realisation of the full potential of the circular economy in the renewable materials sector.

Governments and private sector entities that prioritise investments in recycling facilities, waste management systems, and renewable energy infrastructure will come out ahead.

By taking steps now to modernise and expand sustainable infrastructure the early movers will create a more resilient and resource-efficient economy that both minimises environmental impacts and maximises economic opportunities.

Embracing the circular economy: A sustainable tomorrow

Achieving a circular economy in the renewable materials sector requires a multifaceted approach that addresses technological, regulatory, and economic challenges.

By embracing innovation, collaboration, and sustainable practices, the hurdles faced can be overcome, and a resilient and resource-efficient future can be built. 

With concerted effort and collective action, the materials sector will be able to navigate the complexities of this transition to create a world where waste is minimised, resources are maximised, and environmental responsibility is front and centre for all key stakeholders.
