Selective adsorption

Envirotec Magazine

The crystal structure of the K-GIS zeolite adsorbent: The size of cavities in the crystal is slightly larger than the CO2 molecule, permitting CO2 to enter the crystal and be adsorbed while larger molecules such as methane are excluded. Biogas from sewage sludge, garbage, and similar sources consists of approximately 60% methane and 40% CO2.

CH4nge is in the air? Comparing laser and FID for landfill emissions monitoring

Envirotec Magazine

The accurate and effective monitoring of surface methane emissions levels is critical to the safe operation of landfill and waste management sites. However, methane monitoring equipment can sometimes be more of a hinderance than a help. Another way? It is able to detect emissions from 1-10,000ppm or from 0.1%

Could trash-to-energy technology feed hydrogen demand?

GreenBiz

Early pioneers of these hydrogen-from-waste technologies such as Ways2H, SGH2 Energy (SGH2) and Standard Hydrogen say not only are they making carbon-free, energy-rich fuel, their approaches also will divert mountains of trash from landfills and waterways, cutting greenhouse gas emissions. . There are other ways to make hydrogen.

Anaerobic digestion trade body calls for ban on Russian natural gas imports in open letter to the UK Prime Minister

Envirotec Magazine

In fact, converting biomethane to green hydrogen can be net negative. Finally, biomethane is generated by recycling methane emitting organic wastes. Therefore, the AD sector alone could deliver 20% of the UK’s commitment to the Global Methane Pledge. Russia has put a six-month moratorium on the export of mineral fertiliser.

More reflections about regenerative grazing and the future of meat

GreenBiz

I’d argued that regenerative grazing could cut emissions from beef production , helping reduce the outsized contribution cattle make to food’s carbon footprint. We tend to blame cows’ methane-filled burps for these gases, but around a quarter of livestock emissions come from fertilizer used to grow animal feed. Sounds great, right?
