The Wisconsin Department of Natural Resources (DNR) is now accepting applications for the new E-Cycle Wisconsin Electronics Collection Grant for projects that will host an electronics collection site or event, or series of collection sites or events, in 2022 or the beginning of 2023. “Protecting our precious natural resources and world-class outdoor spaces is key to protecting our way of life here in Wisconsin,” said Gov. Tony Evers. “And as electronics have become an everyday part of our lives, we have to ensure every community has ways to recycle them and reduce their waste. That’s why I’m proud to have signed Act 79 into law, which will provide resources to local communities, Tribal Nations, businesses, and nonprofits so they can collect electronics waste and keep their environments safe and clean for kids and families to enjoy for generations.”

We present a software system for fused deposition modelling 3D printing that replaces infill material with scrap to reduce material and energy consumption. Example scrap objects include unused 3D prints from prototyping and calibration, household waste like coffee cups, and off-cuts from other fabrication projects. To achieve this, our system integrates into an existing CAD workflow and manages a database of common items, previous prints, and manually entered objects. While modelling in a standard CAD application, the system suggests objects to insert, ranked by how much infill material they could replace.
Natural gas supporting the development of renewables Natural gas is an important part of the global effort to reduce emissions, particularly as a partner to variable renewable energy – the fastest growing sources of power in power grids across the world. Natural gas generated power is important as it can respond quickly to changes in solar and wind supply, such as on cloudy or still days, therefore helping to maintain reliable electricity supply to customers. This certainty of supply is particularly important to manufacturers and other energy intensive industries. Other technologies that can play a role in firming variable renewables are pumped hydro and batteries.
Indian Institute of Guwahati (IIT-G) on Monday said it has signed a memorandum of understanding with a private, deemed university based in Coimbatore to help enrich academic programmes and promote an exchange of students between the two institutions. The MoU was signed by Prof G Sitharam, Director, IIT-G, and Dr Venkata Rangan, Vice-Chancellor of Amrita Vishwa Vidyapeetham (AVV) in this regard recently, an official release said. Highlighting the different aspects of this partnership, Prof Sitharam, said, “With the emergence of many new interdisciplinary research and academic centres equipped with state-of-the-art equipment at IIT-Guwahati, the institute is destined to serve the country with extra vigour.
Many people struggle with trying to be good environmental stewards – while not being hoarders at the same time. I’ve been guilty of holding on to things that I should throw away, just because I haven’t yet found a way to recycle them.
