Waste management: decentralizing for better management

gestion des déchets, waste management

Reducing the environmental impact of waste and encouraging its reuse calls for a new approach to its management. This requires the modeling of circuits on a territorial scale, and the improvement of collaboration between public and private actors. Territorial waste management is one of the fundamental aspects of the circular …

Economics – dive in, there is so much to discover!

économie circulaire, impact environnemental

To effectively roll out circular economy policies within a territory, companies and decision-makers require access to evaluation and simulation tools. The design of these tools, still in the research phase, necessarily requires a more detailed consideration of the impact of human activities, both locally and globally. “The circular economy enables …

Our indoor air is polluted, but new materials could provide solutions

air intérieur

Frédéric Thévenet, IMT Lille Douai – Institut Mines-Télécom We spend 80% of our lives in enclosed spaces, whether at home, at work or in transit. We are therefore very exposed to this air, which is often more polluted than outdoor air. The issue of health in indoor environments is thus …

Covid-19: what could subsurface wave detection mean for the pandemic?

detection covid-19 eaux usées

The detection of SARS-CoV-2 viral infections responsible for Covid-19 allows us to monitor the evolution of the pandemic. Most methods are based on individual patient screening, with the disadvantages of cost and time. Other approaches based on the detection of SARS-CoV-2 in urban wastewater have been developed to monitor the …

What is life cycle analysis?

LCA

Life cycle analysis (LCA) is increasingly common, in particular for eco-design or to obtain a label. It is used to assess the environmental footprint of a product or service by taking into account as many sources as possible. In the following interview, Miguel Lopez-Ferber, a researcher in environmental assessment at …

Managing electronic waste: a global problem

Responsibilities surrounding digital waste are multi-faceted. On one side, it is governments’ responsibility to establish tighter border controls to better manage the flow of waste and make sure that it is not transferred to developing countries. On the other side, electronic device manufacturers must take accountability for their position by …

Agricultural sediments transported by rivers

Flood, soil erosion

The QuASPEr project studied the Canche river basin in northern France to better understand the phenomenon of soil erosion and its related consequences. This knowledge aims to develop effective land management methods for municipalities without negatively affecting farmers’ work.   Heavy rain, dry land, sloping ground that has been tilled… …
