Identifying innovation barriers using a Delphi method approach: the case of technical lignin in the wood-based panel industry.

摘要

About 50 million tons of lignin are produced annually in the pulping industry worldwide. A traditional example for lignin research is its use as a resin additive in wood based panels. The aim of this study was to find out why technical lignin has not so far succeeded in substituting for phenolic resins in the wood based panel industry. Interviews were carried out using a multistage expert interview approach adapted from Delphi methods. After the principal factors were identified and verified, quantitative data were taken for the valuation. Technical product properties received the highest ratings by the consulted experts, followed by security of supply, price difference and productivity, which received almost the same overall ratings. Interestingly, researchers rated security of supply much lower than the industry representatives. Depending on fulfilment of criteria identified, the experts expected that between 10 and 30% of phenolic resin can be potentially substituted within the next 10 years.
