Plant-based biofilters purify building air
A team of American researchers and Buro Happold successfully tested a biofilter that utilizes plants and microorganisms to reduce carbon dioxide levels inside buildings to below outdoor air levels, using the process of photosynthesis. This solution aims to diminish the accumulation of carbon dioxide within buildings, which can sometimes reach 700-1000 parts per million and pose health risks—especially as projections suggest atmospheric levels could reach 936 parts per million by 2076. Plant-based technologies are relatively simple solutions; however, their efficiency heavily depends on factors such as airflow and lighting. They may also contribute to improving the microbial composition of indoor air. The study's findings will be presented at the "Lighting Cities" conference, with the goal of integrating green solutions into urban environments, focusing on enhancing indoor air quality and public health.
