Circular Economy Practices for Low Carbon Chemicals

Detailed overview of innovation with sample startups and prominent university research


What it is

Circular economy practices in the chemical and fertilizer industries aim to minimize waste generation and maximize resource utilization by closing the loop in production processes. This involves shifting from a linear “take-make-dispose” model to a circular model where materials are reused, recycled, and repurposed, reducing reliance on virgin resources and minimizing environmental impact.

Impact on climate action

Circular Economy Practices in Low-Carbon Chemicals & Fertilizers foster sustainable resource utilization, reducing emissions and waste. By recycling and repurposing materials, it minimizes environmental footprint, promotes efficiency, and lowers production costs. This innovation accelerates the transition to a circular economy, crucial for mitigating climate change and achieving sustainability goals.

Underlying
Technology

  • Waste as a Resource: Circular economy practices view waste materials as valuable resources that can be utilized as inputs in other processes. This requires identifying and developing technologies that can effectively recover and process waste streams.
  • Industrial Symbiosis: Collaboration between different industries enables the exchange of waste materials and byproducts, creating a symbiotic relationship where one industry’s waste becomes another’s valuable resource.
  • Product Life Extension: Designing products for durability, repairability, and reusability can extend their lifespan, reducing the need for new production and minimizing waste generation.
  • Chemical Recycling: Advanced recycling technologies can break down complex chemical compounds into their constituent building blocks, allowing for the recovery and reuse of valuable materials.

TRL : Varies depending on the specific practice and technology. Some circular economy practices, such as industrial symbiosis, are already being implemented in various industrial clusters (TRL 7-8). However, the development and deployment of advanced chemical recycling technologies are still in progress, with TRLs ranging from 3-4 to 6-7.


Prominent Innovation themes
