The global chemical industry is increasingly shifting from pilot-scale circularity initiatives toward securing commercial volumes of recycled feedstocks, with BASF and Texas-based Encina strengthening their partnership around chemically recycled benzene production.
The collaboration moves beyond a conventional offtake agreement, giving BASF a potential role in Encina’s future project development while highlighting the broader challenges of scaling chemical recycling infrastructure.
Under the expanded agreement, BASF will support Encina during the development phase of its planned commercial-scale chemical recycling facility, including procurement strategy and project execution planning. The partnership also provides BASF with rights to participate in future Encina projects, including the possibility of becoming an equity partner.
The move represents a shift in how major chemical producers approach circular raw materials. Rather than simply purchasing recycled feedstocks after production begins, companies such as BASF are increasingly seeking involvement earlier in project development to manage supply security, technical risks, and commercial alignment.
Thomas Ohlinger, senior vice president of traded products at BASF, said the agreement reflects BASF’s ability to support early-stage projects beyond the traditional buyer-seller relationship.
Encina is targeting a final investment decision for its first commercial-scale facility approximately 18 months after project kickoff, assuming progress across engineering, permitting, commercial agreements, and financing. The planned facility is expected to produce approximately 175,000 metric tons annually of circular benzene, along with circular methane and other co-products.
The project’s scale has evolved significantly during development. Encina increased its planned processing capacity from roughly 40 tons per hour to 50 tons per hour, equivalent to approximately 375,000 metric tons per year of input capacity. The company attributed the expansion to customer demand and the decision to move its project focus from Pennsylvania to the US Gulf Coast.
The previous Pennsylvania project was canceled in 2024 following community opposition, adding to the regulatory and social challenges facing large-scale chemical recycling projects. The relocation reflects a broader industry trend: new circular chemical facilities are increasingly being planned in regions with established petrochemical infrastructure, pipeline networks, and access to existing chemical manufacturing clusters.
Encina’s planned Gulf Coast location aligns with BASF’s existing operations. The company consumes benzene at its Freeport, Texas facilities, which sit within one of the largest chemical production corridors in the United States. The region provides logistical advantages through established infrastructure and proximity to other chemical producers.
Benzene remains a critical building block across the chemical value chain. Derived products include styrene, nylon intermediates, synthetic rubber components, polyurethane materials, and various specialty chemicals used in packaging, automotive applications, medical products, and durable goods.
For BASF, circular benzene could support its broader strategy around recycled and alternative feedstocks. The company has been developing its Ccycled product portfolio, which relies on alternative raw materials intended to reduce dependence on fossil-based inputs. However, questions remain across the chemical recycling sector regarding how circular outputs are tracked and allocated, particularly when recycled feedstocks enter complex global supply chains.
A recurring criticism of chemical recycling models involves transparency around the actual destination and environmental impact of recycled materials. Many agreements involving circular feedstocks do not disclose specific downstream applications, making it difficult to determine whether recycled molecules directly replace virgin fossil inputs or are managed through mass balance accounting systems.
Encina stated that BASF intends to use circular feedstocks from its facilities within BASF’s own manufacturing operations and product portfolio rather than acting solely as a marketing intermediary.
The company’s technology uses catalytic conversion to transform plastic waste into chemical products, although final yields depend on feedstock composition and continued engineering development. Feedstock variability remains one of the major challenges for chemical recycling projects, as plastic waste streams often differ in composition, contamination levels, and availability.
Encina said its technology was designed to handle variable feedstocks, a factor it considers essential for commercial-scale operations. However, achieving consistent output quality and predictable economics remains a key challenge for the sector.
BASF’s interest in recycled benzene also aligns with its expanding chemical production footprint in North America. At its Geismar, Louisiana site, the company is preparing to complete an expansion of methylene diphenyl diisocyanate production, increasing North American MDI capacity to approximately 600,000 metric tons annually. The expansion represents nearly a 60% increase compared with capacity levels before the project began in 2019.
The concentration of chemical production assets along the Gulf Coast creates potential advantages for circular feedstock integration. Existing infrastructure, including pipelines and shared industrial networks, allows companies to move raw materials efficiently between production sites.
Encina is also developing commercial relationships beyond BASF, including a supply agreement with styrenics producer AmSty and reported relationships with other chemical companies, including Covestro.
