Utilization of waste sodium sulfate from battery chemical production in neutral electrolytic pickling
2021
Several industrial activities produce metal sulfates, which are controlled by strict limitations for wastewater concentrations of sulfate. One emerging area where these activities occur is the production of lithium-ion battery chemicals in which sodium sulfates are formed because of cathode precursor co-precipitation. Several solutions for sulfate removal exist, but one option is to reuse the sulfate side stream in other processes to increase circular economy and atom efficiency. In this paper, the reuse of sodium sulfate solution in a steel industry pickling solution is considered. Neutral electrolytic pickling experiments were carried out to compare the pickling behavior of the electrolyt…
What hampers green product innovation: the effect of experience
2019
Based on representative firm-level survey data for Austria, Germany, and Switzerland, this study systematically analyzes the relevance and drivers of barriers to green product innovation using the example of green energy technologies. “Low willingness to pay”, “high development costs”, “high commercial uncertainty”, and “lack of favorable political framework” are identified as the most important barriers. Moreover, we find that the firms’ innovation experience is an important driver of the level of green innovation barriers. Green innovation barriers are more accentuated for firms with green innovation activity than for firms with no green innovation activity. However, experience from diffe…
