Methane to energy
“The latest plant in Domlur was set up in October 2015 and has been fully functional over the last week. It produces around 40 KV power to light up 44 lamps installed in the park premises and one high-mast lighting unit in the area,” BBMP assistant engineer (electrical) Manjappa told BM.”
“Around 45 tonnes of cowdung is fed into the main digester for the culturing process. After 10-15 days of culturing, methane gas begins to build up in the tank, which is indicated by the lifting of the dome of the tank from its dormant position. Green waste is fed starting at 500 kg per day, and is increased by 500 kg every fortnight to reach a peak feeding of 5,000 kg per day. Methane gas, thus generated, is stored in a balloon of 80 cubic metre capacity. At the plant site itself, some gas is used for running the turbine that generates power.”

Emerging role of wetland methane emissions in driving 21st century climate change
How peat could protect the planet
One complication in the effort to re-wet peatlands is that restored wetlands will produce some amount of methane, which is a potent greenhouse gas. But Joosten says that this will be more than balanced by the reduction in emissions of carbon dioxide and nitrous oxide. Overall, re-wetting has a net benefit for the climate. Rather than aiming to turn global peatlands into sinks, he says, a more realistic near-term goal is to make bogs carbon neutral.
Mitigation of methane emissions from constructed farm wetlands
use of constructed wetlands for wastewater treatment may therefore result in ‘pollution swapping’ by increasing CH4 emissions (Reay, 2004)

The amount of CH4 emitted from wetland soils is determined by the balance between CH4 production and consumption

Oyster mushrooms grown on wetland reed bed to form mycelium blocks and infill formwork. Capturing methane produced by constructed wetlands
Hope elevates, and joy Brightens his crest; as when a wandering fire, Compact of unctuous vapour, which the night Condenses, and the cold environs round, Kindled through agitation to a flame, Which oft, they say, some evil Spirit attends, Hovering and blazing with delusive light, Misleads the amazed night-wanderer from his way To bogs and mires, and oft through pond or pool; There swallowed up and lost, from succour far.
Twitter brain has been making me feel guilty about expecting anyone to read more than 140 characters on this, so I will attempt to absolve myself with a tl;dr on interesting things that fell out of it in as few tweets as possible…
Research on OSB as the base for mycelium infused construction suggests ways to form CO2 -ve structures and combined with the ecology of a constructed wetland could re-create a Renaissance Grotto as landscape retreat…
And the wetland peat formation is a vital CO2 sink, but there’s a danger of ‘pollution swapping’ from additional methane creation…
Which we may be able to mitigate but perhaps we can also plan for collection and use in controlled ways, like lighting, kilns or rockets…
or accidentally awaken a long lost microbial extremophile species…
and we need to plan ahead because OSB, a much used building material, appears to be a poorer CO2 sink than other timber materials when it eventually ends up below ground…
