Historically, wastewater treatment has focused on disinfection and reducing nutrient concentrations, but there is now growing concern over the increased concentrations of pharmaceutical compounds in agricultural and human wastewater. More comprehensive conventional wastewater treatment, however, leads to increased resource and energy consumption and greenhouse gas emissions. Living Machines are alternative, decentralized ecological wastewater systems that have been successful at disinfecting and reducing nutrient loads in wastewater with lower capital and operating costs and improved energy efficiency. We conducted preliminary experiments using small-scale Living Machines to test their effectiveness at reducing a common pharmaceutical, ibuprofen, which is increasingly used in the agricultural sector and for human health. We found that these Living Machines were efficient and effective in reducing concentrations of ibuprofen in wastewater, even at input levels much higher than reported in the literature, and hence show promise for a range of possible applications.
Background “It is important that the consideration of carbon removal be pushed beyond technical consideration of ’how much carbon at what cost’ and beyond the boundaries erected by too-narrow readings of climate modeling results towards much deeper examination of the social, environmental, political, and other implications.” ~ Simon Nicholson Climate change is a universal problem that […]
In this briefing, we delve into how different communities of interest describe wellbeing and use it to improve lives. Broadly speaking, these discussions embrace personal wellbeing, community wellbeing, and societal wellbeing. We end with a short discussion of how these concepts are used by governments to promote wellbeing of populations.

Liz Marshall (Liz Mars) and Bullfrog Films As someone who chooses plant-based foods in order to lessen the climate and environmental impacts from conventional meat production, I am encouraged by Meat the Future, directed by Liz Marshall. This documentary highlights a hopeful advancement in food science and a possible solution for inhumane greenhouse gas producing large-scale…Keep reading

Dollar values assigned to economic activity, through ignorance or design, can be misleading. There is an objective, scientific currency that can serve as a check on money-based reports on how much a nation has produced.
Part 1 of this discussion dealt with differences between Socialist and Anarchist perspectives on the global situation and on implications for the form a sustainable and just society must take. Part 2 explains how an understanding of our situation and the social form required to resolve it leads to implications for revolutionary strategy which also contradict those within traditional Socialist theory and practice.
Last month, I was invited to participate in a panel discussion related to the development of Parque Intraurbano Jurica in Querétaro, Mexico. It was an honor to join my colleagues Drs. Javier Carillo (The World Capital Institute), Cathy Garner (University of Lancster), and Patrizia Ingallina (University of the Sarbonne) to share reflections on harmonizing ecology and equity in contemporary urban park development. This blog provides a summary […]
