A comparison between electrochemical carbon dioxide conversion and reforestation is presented. By comparing thermodynamic and forestry data, recommendations for technology development can be made. With the global average temperature steadily increasing due to anthropogenic emission of greenhouse gases into the atmosphere, there has been increasing interest worldwide in new technologies for carbon capture, utilization, and storage (CCUS). This coincides with the decrease in cost of deployment of intermittent renewable electricity sources, specifically solar energy, necessitating development of new methods for energy storage. Carbon dioxide conversion technologies driven by photovoltaics aim to address both these needs. To adequately contribute to greenhouse gas reduction, the carbon dioxide conversion technology deployed should have a substantially higher rate of carbon dioxide removal than planting an equivalent-sized forest. Using consistent methodologies, we analyze the effectiveness of model photovoltaic-driven carbon dioxide conversion technologies that produce liquid alcohols as compared to planting an equivalent forest. This analysis serves to establish an energy use boundary for carbon dioxide conversion technology, in order to be a viable alternative as a net carbon negative technology.

Lack of data on available agriwaste by type of source, local variations in agricultural consumption, and the uncertain feasibility of industrial scaling, all contribute to the challenges of developing commercially viable agriwaste-to-resource building products. Materials Passports linked to Building Management Information systems are tools that can improve regional planning efforts and the coordination of sustainable supply chains focused on new product development and product stewardship. Globally, an estimated 3.5 kg per capita of daily agricultural waste is transferred to municipal landfills. Stated differently, 7.8 billion people generate 26.25 billion kg of daily agriwaste. Numerous studies established linkages between leachates from solid waste landfills, bioaccumulation of toxic chemicals, and greenhouse gas emissions that are a leading cause of climate change. Furthermore, raw material scarcity threatens to constrain economic growth and productivity. Sustainable circular economy practices focus on increased efficiency and a decoupling of wasted natural resource consumption from economic growth. Academic and industry researchers are focused on developing circular economy solutions that increase resource efficiency while decoupling wasted natural resource consumption from economic growth. Human acceptance and adaptation of technology are ideologically, culturally, and socio-technically dependent. Waste banana peels are used as an analytical scenario of how BIM modeling can improve the production of localized, affordable, and culturally appropriate building materials. Ideological and cultural norms are a precursor for socio-technical acceptance. Building material selection is examined from the perspective of complex factors creating uncertain economic valuations, and socio-cultural variations in the definition of waste. The objective of the research is to open multidisciplinary examination of the practices and choices that determine affordably safe building materials.

The circular economy aspects of PET (polyethylene terephthalate) waste conversion into value-added products are discussed concerning different governmental policies and industrial protocol for plastic degradation. The use of microbial enzymes such as PET hydrolase is discussed regarding PET (polyethylene terephthalate) degradation. The primary purpose of this perspective is a critical analysis of the correlation of the current state-of-the-art rising circular economy platform enacted across the world with close looping of PET (polyethylene terephthalate)-based plastic polymer disposal and sustainable recycling and upcycling technology. The goal of the upcycling process is to get the low-cost value-added monomer than those obtained from the hydrocarbon industry from the sustainability prospect. A summary of the circular bio-economic opportunities has also been described. Next, how the PET hydrolase enzyme degrades the PET plastic is discussed. It is followed by an additional overview of the effect of the mutant enzyme for converting 90% of plastics into the terephthalate monomer. A site-directed mutagenesis procedure obtains this particular mutant enzyme. The diversity of different microbial organism for producing PET hydrolase enzyme is finally discussed with a suggested outlook of the circular economy goal from the viewpoint of plastic degradation objectives soon.

Energy recovery from waste treatment and growing biomass is of great significance for the energy management and sustainable energy supply. It is shown that biomass and various wastes containing carbon are able to significantly contribute to the energy sector. We describe a possible scenario for the energy development of an European country of the future. In addition to solar, wind, and hydrogen energy, priority should also be given to generating energy using small-sized gasifiers. First, it is sustainable energy since biomass and household waste are always available. Second, this approach will allow us to launch local electric power grids instead of the unified state and interstate grids, which will reduce up to three times the consumption of energy raw materials and financial resources. Third, a new design of electric motors, namely torus motors, will allow one almost halve electricity consumption and open a gateway to new technologies.
