ISCC PLUS as a key factor for the circular economy

June 18, 2026

The current rise in oil prices due to geopolitical tensions – for example in the Middle East – underscores once again the high dependence of our industries on a stable and affordable supply of raw materials. Rising prices and volatile markets increase the pressure on companies to secure alternative sources of supply, for example by recycling waste into secondary raw materials.

However, the mere availability of cheap raw materials is insufficient. Companies today are no longer only under cost pressure, but also facing increasing regulatory and societal expectations: customers, investors, and legislators are demanding greater transparency regarding the origin of materials and the conditions under which they were extracted or manufactured. Without reliable documentation, companies risk reputational damage, regulatory consequences, and the loss of market opportunities.

As the importance of sustainable raw materials grows, so does the demand for their credibility. The more complex and global value chains become, the more difficult it is to reliably trace the origin, composition, and actual sustainability of materials.

Sustainability requires verifiability

Right here sets ISCC PLUS (International Sustainability and Carbon Certification). The certification system creates transparency, comparability, and trust along the entire supply chain. It is therefore increasingly becoming a key standard for a modern, sustainable plastics, chemical, and recycling industry.

A key element of ISCC PLUS is the so-called mass balance approach. Since recycled and fossil raw materials often cannot be physically separated in industrial processes, this model enables a computational allocation of sustainable shares along the entire production chain.

This allows products made from mixed material streams to be certified as sustainable – provided all material flows are transparently documented and auditable. This approach is essential, especially for innovative recycling processes in the field of advanced recycling, such as those operated by enespa. Without reliable evidence, sustainability often remains a promise – only with ISCC PLUS does it become verifiable.

Market access, credibility and competitive advantages

The significance of ISCC PLUS today extends far beyond mere compliance. Although it is a voluntary system, for many companies certification has long since become a prerequisite for market access. This is due to several reasons:

Industry partners are demanding more and more certifications – where these are lacking, trading in raw materials is becoming increasingly difficult.
ESG requirements from both legislators and private investors are constantly increasing.
In particular, investors are increasingly paying attention to verifiable sustainability strategies, and their absence is considered a risk.
At the same time, ISCC PLUS offers companies the opportunity to position materials specifically as sustainable – and thus also to realize economic added value.

Pyrolysis oil is transformed from a waste product into a certified raw material.

The importance of ISCC+ is particularly evident in the example of pyrolysis oil, which is obtained from mixed plastic waste. The technological production process is already established. However, without the corresponding certification, its integration into industrial value chains remains limited.

Only through systems like ISCC PLUS does an intermediate product become a recognized, tradable raw material that meets the requirements of industry, regulation and the market alike.

For enespa, this leads to a clear conclusion: Technology alone does not determine the success of chemical recycling. Equally crucial is the ability to integrate these products into existing market and regulatory structures and to transparently demonstrate their sustainability.

The path to ISCC PLUS certification is difficult but essential.

Implementing ISCC PLUS is not a one-time step, but a structured and continuous process. This includes the following steps:

All input and output materials must be fully recorded and traceably documented to ensure transparency along the entire value chain.
Companies must establish a system that enables the mathematical allocation of sustainable raw materials and meets the requirements of certification bodies.
Existing processes need to be reviewed and partially restructured, with clear responsibilities and employee training playing a central role.
Compliance with the requirements is monitored through recurring inspections, thereby ensuring continuous quality assurance.
For many companies, this means a considerable organizational effort. At the same time, this very system creates the foundation for long-term market acceptance.

Why enespa offers technology and certification from a single source

At this interface between technology and regulation, enespa positions itself as an integrated solutions provider. In addition to developing and building plants for converting plastic waste into high-quality raw materials, enespa also supports the certification-relevant processes along the value chain.

As part of its service offering, enespa specialists provide targeted support to companies in implementing ISCC PLUS requirements:

We record and analyze existing material flows to create transparency and establish a solid basis for certification.
Based on the identified material flows, we work with our customers to develop systems that enable a traceable and auditable allocation of sustainable raw materials.
We provide support in the structured preparation for certification audits and accompany the entire process to ensure a smooth and successful execution.

This is complemented by laboratory capacities for the characterization and quality assurance of raw materials such as pyrolysis oil. This integrated approach makes it possible to directly translate technological innovations into marketable, certified solutions.

ISCC PLUS is increasingly becoming an enabler of the circular economy.

ISCC PLUS is far more than a certificate. It is a key enabler for scaling up sustainable raw materials – and thus a crucial building block for the industrial implementation of the circular economy.

Companies that adopt certified processes early on not only create regulatory certainty but also strategic competitive advantages. Because in an increasingly sustainability-driven industry, it's not just what is produced that counts – but also how it is produced. comprehensible It is.
