Doing double duty creating energy, cutting emissions: A unique organic waste-conversion concept

Municipal Solid Waste (MSW) is big business. But being big business doesn’t necessarily ensure profitability. The recycling industry as a whole, meanwhile, after holding its own for several decades at least, today the outlook, truth be told, appears less rosy.

The climate change exchange: ‘Back-up’ plan

Whether we are talking about atmospheric normalization or global warming’s and/or climate change’s causation, “balance” is the word. That’s right, balance. So in a kind of holistic air-healing sense or maybe more precisely, a holistic air-remedying context, what does being balanced mean exactly? From physics, we know that if an object exerts a force opposite … Read more
