As the concentration of carbon dioxide (CO2) in atmosphere continues to rise, and reality global warming challenges hits world, research societies are developing innovative technologies address climate change brought about by high atmospheric CO2. One such is direct removal CO2 from atmosphere. Among all currently available technologies, air capture (DAC) positioned deliver needed because it independent emission origin, machine can be stationed anywhere. Research efforts last two decades, however, have identified system overall energy requirements as bottleneck realization DAC's commercialization. a result, community seek better ways minimize required per ton removed via DAC. In this work, literature was comprehensively reviewed assess progress made DAC, its associated advances state-of-the-art. Thus, proposed use traditional heating, ventilation, conditioning (HVAC) (mainly system), preexisting technology, directly atmosphere, that provided HVAC choice.

Coupling Waste Feedstocks to Microbial Protein Production in a Circular Food System

ACS Sustainable Chemistry & Engineering, Journal Year: 2025, Volume and Issue: unknown

Published: Jan. 2, 2025

Global food production is a major contributor to greenhouse gas emissions, water consumption, and land use. As an alternative conventional agriculture, the of waste-derived microbial protein (MP) holds promise for reducing environmental impacts. MP can be mass-produced in volumetrically scalable fermentation processes on short time scales, enabling facile scale-up with lower use, impacts than animal and, some cases, plant protein. also produced from waste feedstocks, diverting landfills or natural environment. This Perspective explores availability suitability feedstocks production, suggesting that generated United States could fulfill twice current national demand. We discuss biotechnological separations required produce food-grade human consumption waste. Key challenges include consistency, consumer regulatory acceptance, process utilities (electricity, heat, nutrients) account up 85% costs most impacts, all which present opportunities innovation microbiology design spaces. Overall, this work highlights potential contribute more circular, resilient, sustainable system.
