New method converts old phones and paper industry #waste into #GreenBattery tech
Scientists have created a sustainable, cost-effective, and highly efficient solution that promotes a #CircularEconomy while supporting the transition to greener #EnergyStorage.

"It is a stunning example of circular economy innovation. Rather than letting these materials sit in #landfills or go up in smoke, the team from China is giving the waste a high-tech second life.
"When tested as a sodium-ion battery anode, this composite of #nickel-#cobalt sulfides and #lignin-derived carbon delivered electrochemical results."

#Earth4All #Argentina: Young people confront today’s challenges through debate
At a time when social and environmental crises are deepening, this initiative shows that young people are not just aware of the challenges—they are ready to lead the transformation. The real challenge is to listen to them and make room for their voices in the creation of truly transformative public policies.
5 June 2025
"On 9 May, young people between the ages of 18 and 30 gathered simultaneously in #Córdoba, #BuenosAires, and #Tucumán to take part in the workshop 'Understanding the present to build the future we want,' part of the Earth4All Argentina National Engagement Strategy led by the #ClubOfRome – Argentinian Chapter.
"Organised in collaboration with #FundaciónAlimentaris and #JóvenesPorElClima, the workshop was part of the participatory process of the National Participation Program (NEP), an initiative aimed at gathering diagnostics, experiences, and proposals from local communities to influence public policy. Its goal is to collectively adapt the international Earth4All model to local realities. The model warns of the urgent need to move away from the current path, described as '#TooLittleTooLate,' and to move toward a '#GiantLeap' centred on #social and #EnvironmentalJustice. This transformative agenda is structured around five turnarounds: #EradicatingPoverty, #ReducingInequality, #EmpoweringWomen, transforming #FoodSystems, and driving the energy transition.
"The workshop brought together university students from the host cities, #grassroots and #EnvironmentalActivists, and civically engaged youth eager to influence #LocalPolicies and practices. Facilitated by Jóvenes por el Clima, the event was organized around two main dynamics: first, introducing the foundations and challenges of the Earth4All model; and second, mapping specific local issues and working in thematic groups aligned with the model’s five pillars, with the aim of #CoCreating concrete proposals grounded in the experiences and voices of #YoungPeople."

We need this tech NOW! Some #LithiumIon alternatives discussed are #SodiumIonBatteries, #HydrogenFuelCells and #AqueousMagnesiumBatteries (which I'm just learning about).
6 alternatives to lithium-ion batteries: What's the future of energy storage?
The future of battery tech looks bright, but we might have to wait a while.

March 11, 2024"Li-on batteries require environmentally destructive #mining practices for metals such as #lithium, #cobalt, and #nickel. Moreover, a large amount of these metal resources are located in developing countries like the Democratic Republic of Congo [#DRC]. Ethical mining practices haven’t been established in these areas yet, meaning Li-on production contributes significantly to greenhouse gas emissions."
