Production of Algae-Based Carbon Black Pigment and Its Use in Carbon Neutral Printing Technologies

Abstract

Within the scope of the project, we focused on the innovation potential in printing technologies, which is a common problem for all sectors, taking into account the contribution of chemistry to sustainability in innovation-oriented sectors. Based on the importance of microalgae in biomass, we obtained biochar for the production of carbon black pigment. Biochar provided an important result especially in the production of a pigment that has the potential to replace petroleum-derived carbon black pigment from fresh and salty algae such as Spirulina and Nannochloropsis. By using the raw pigment material we obtained together with environmentally friendly vegetable resins, we turned it into a product with low volatile organic compounds and no heavy metals. In this context, we examined the potential of the product formed in many dierent sub-elds of biochar printing technologies such as direct printing, UV curing and printing. With biocompatibility experiments, we also examined the status of the project in terms of human and environmental health. Thus, we have obtained preliminary findings on the transition from biomass to printing technologies, which has the potential for an important sectoral change. It will be possible to obtain more qualified and comprehensive products with future experiments. This transformation has the potential to affect many stakeholders for production and consumption.
