The aim of this thesis is to determine the relevant factors of environmental product innovation. This new more complex innovation, which requires environmental and competitiveness performance for its development and diffusion, occupies a more and more central place in the firm. We have in this work particularly analyzed the effectiveness of voluntary approaches (namely the European Ecolabel certification) on the innovation of products in the firm and, at the same time, identified the key determinants to adoption of this ecolabel. We focused our analysis on the detergents and maintenance-products sector in France. This study is a part of an evolutionary approach and considers the process of technical change (development and diffusion of European Ecolabel certified product) to be a complex and uncertain process incorporating different factors in co-evolution, beyond a limited conception of the role of environmental policies. The case study shows the role of the firm strategy in the process of technical change. The empirical analysis confirms the role of this determinant (strategy of suppliers of bimolecular substances) and presents, moreover, the importance of regulation (REACH…), the benefits of certification (brand image) and demand as key factors in adoption of this ecolabel certification. Indeed, although this voluntary policy drives some firms to innovation, the environmental performance and accession by most firms in this sector remains a challenge. In the current context, firms which have used biomolecular substances, under suppliers' strategic influence, have developed green products but not systematically European Ecolabel certified products

The regeneration of Cleaning In Place (CIP) solutions is interesting, both economically and environmentally, especially in dairy industry. The CIP’s key step lies on the alkaline washing which ensures the removal of organic contaminants deposited on the equipment. This washing is generally done by soda lyes, less expensive than potash ones. Our work aimed to apply a physicochemical regeneration process, based on adsorption-coagulation-flocculation phenomena, on potash lyes to make their integration in the dairy CIP affordable. The regeneration of potash solutions soiled with milk was examined and compared with the soda solutions regeneration. The process effectiveness to purify potash solutions in terms of COD and TN reduction has been shown. The solutions analysis has also highlighted the improvement of their interfacial properties (surface tension, contact angle). These properties, whose origin was attributed to the accumulation of biosurfactants, confer to potash regenerated solutions a best cleaning power. This point was validated during cleaning assays of organic ultrafiltration membranes fouled by milk proteins. The optimization of solutions formulation has also enabled obtaining a cleaning performance as efficient as those of a commercial detergent largely used for this type of application. Finally, economic and environmental impacts of the potash lyes integration in substitution to soda ones were evaluated for dairy industrial CIP through a techno-economic analysis and a Life Cycle Assessment (LCA)
