Advances in cleaner technologies have a critical role in reaching Europe’s climate and environmental goals. More precisely, in the case of the footwear bonding process its environmental impact is mainly related to the VOCs emissions resulting from the use of organic solvents in the most common adhesives used, as well as during the application of some surface treatments such as halogenation. Moreover, the use of raw materials of fossil origin also contributes to its carbon footprint. The aim of this work is to deploy cleaner technologies to minimise the environmental footprint of the footwear bonding process through several approaches at different steps of the process life cycle, also to contribute to footwear circularity. This work focuses on the synthesis and application of reactive hot melt polyurethanes from CO2-based polyols as biobased adhesives, and the study of plasma-based surface treatments (low-pressure plasma and atmospheric pressure plasma) to improve adhesion properties, using styrene-butadiene vulcanised (SBR) rubber as a representative footwear soling material. The influence of CO2-based polyols on the polyurethane structure and the physicochemical effects of the plasma treatments on the rubber surface, as well as the final adhesion properties have been evaluated by means of different experimental techniques. The results showed that the values obtained for the T-peel strength of the adhesive joints studied, with the combination of the application of the plasma surface treatments and the biobased reactive hotmelt, exceed the minimum quality requirements for footwear according to the standardised tests. As a result, the deployment of such cleaner technologies regarding adhesives and surface treatments in the footwear bonding process will contribute to improving footwear carbon footprint and its circularity.

The world produces more than 20 billion pairs of shoes every year, and the greenhouse gas emissions of the shoe industry account for 1.4% of the world. This research, taking the knitted footwear industry as an example, combines the concepts of mathematical programming and carbon emissions to discuss the impact of a circular economy sustainable decision-making model (including four carbon tax functions) to achieve net zero emissions under Industry 4.0 on company profits and product structure. The findings suggest that using activity-based costing to measure the attribution of various costs during process improvement allows companies to more accurately capture the carbon cost of producing each pair of shoes. In addition, under the trend of global efforts to reduce carbon emissions, if the price of carbon taxes or carbon rights is not enough to affect companies’ profits, companies will not pay attention to the impact of carbon emissions. To ensure a sustainable production model, the shoe industry should work with brand customers to reduce the effects of products on the environment, coordinate with brand customers’ sustainable development milestones, and formulate a carbon reduction path to achieve zero carbon emission growth goals. Future research can apply these research models, incorporating the carbon tax and carbon rights proposed by this paper to the other industries. In addition, the research also can be extended to explore the consumer behavior for the newly developed knitted footwear.
