PP&A ran a market and product attitudes assessment through expert interviews. In December 2019 the team completed eight in-depth interviews with people who specify, buy, produce or research PA6: a strategic purchaser of engineering plastics for electrical products, a former head of thermoplastics research at an automotive supplier, an automaker's lead for technical polymers, a former polyamide sales director at a major producer, the managing director of a European PA6 producer, a flexible packaging research veteran, a former innovation head at an industrial group in Brazil, and a former materials innovation director at a global apparel company.

The guide moved from each expert's sustainability agenda to the specific case: the value proposition of renewable caprolactam, customer demand and willingness to pay, acceptance of first-generation sugars against recycled feedstocks, the five- and ten-year outlook in Europe, reactions to a new supplier, and the joint development and partnership models that would support entry. PP&A wrote up each interview and consolidated the findings into a summary structured by sector, with a separate section on the sugar supply chain.

The client received a consolidated summary and eight interview write-ups, organized by sector with a separate section on the sugar supply chain. The summary covered how buyers weigh performance parity and supply security, the premium a renewable route could command at entry and over time, what would drive adoption in Europe over the next decade, and which sustainability story would carry with specifiers.

In broad terms, a market for bio-based polyamide existed but was still early. For automotive, packaging and textiles, the summary set out readiness to switch, appetite for a premium and the partnership routes open to a new supplier. It also assessed how much demand a sugar route could serve and the feedstock risks involved. That sector-by-sector view gave the company a basis to decide whether and where to take renewable caprolactam next.
