Wondering about the true cost and impact of using advanced membrane bioreactors for wastewater treatment? A new study in Engineering takes a deep dive into the economics, environmental footprint, and overall sustainability of these high-tech systems. The findings might surprise you!

Balancing economic growth with environmental protection is especially challenging for developing countries, even more so for those relying heavily on foreign aid. Recently, researchers from Japan developed a theoretical framework to show that zero-emissions policies can be compatible with sustainable growth in such nations. Their findings highlight the critical role of foreign aid, clean technologies, and effective tax policies in helping countries reach the minimum income threshold per person needed to effectively implement zero-emissions strategies.
