This methodology is an advanced, integrated waste treatment process that converts up to 80% of municipal sewage sludge into high-purity renewable natural gas. It optimizes energy recovery while significantly reducing the operational costs and environmental impact associated with wastewater management.

#Bioenergy with carbon capture and storage (#BECCS) is a technology that captures and stores carbon dioxide (CO2) from biomass to reduce the amount of CO2 in the atmosphere.

Interesting question here about #Denmark 's rapidly increasing bioenergy use to replace fossil fuels.
Denmark imports wood from USA forests and burns them for electricity.
Yearly increasing emissions from bioenergy mean, the area is expanded yearly as well on which forest is killed for Denmark.

The increasing emissions from LULUCF of this activity are being accounted for in the USA. Or not, who knows.
Likewise, whether Denmark buys wood pellets made from ground litter, as they claim, also no one knows. More likely, profit-smelling private investors are felling old forests/are killing ecosystems.

And all of this for the least efficient energy fuel: wood. One might argue, burning fossil gas is more sustainable because you need less of it for the same amount of energy.

Meanwhile, science is also undecided whether or not old forest stores more carbon than re-planted young forest. I side with old forests anytime –if nothing else, because of the biodiversity it hosts which we can't afford to lose anymore.

Aside from LULUCF emissions accounting, ie disturbed soil, lost sink, there's an important disadvantage in introducing bioenergy use while our myopic economic system governs the dynamics down the line:

greedy profitability and blind Growth!Growth!

AND while Denmark is electrifying formerly fossil fuelled stuff = Growth!Growth!³

Expect growing³ "need" for felled trees. But tree re-growth naturally won't be able to serve this growing demand ➡️the result is, forest area felled increases³ in parallel.

Introducing growing demand for felled trees reminds me of the aviation industry now yodelling "Old cooking fat makes our fuel sustainable!"
All the while planning with 5% growth/year.
Are you guys ready to eat 5% more fish and chips year on year to keep planes flying and satisfy the Growth!Growth! idiocy?

Bioenergy in a closed loop without demand growth is sustainable even with slow-growing trees: assign 1 plot and never allow a second plot. Period.

But in our growth-reliant, profit-driven economic and societal system, when you
create demand for felled trees by
allowing private money to invest in infrastructure and machinery,
the demand grows [for profits=for trees] inevitably as well.

Which then also increases emissions and kills carbon sinks and biodiversity.

Life cycle emission analysis has to account for such systemically driven follow-up dynamics.
And when seen side-by-side, the LCA of renewable energy from PV and wind turbines wins.
PV begets PV, just look at roofs in neighborhoods. You'll seldom see only a single roof with PV. Because of the psychological pull-effect when 1 house gets PV, the neighbours remember that they too "always wanted PV", and now finally see this constant reminder for also starting the project. 🖖🏽

EU:n "hiilidioksidipäästöjen poistosuunnitelma" BECCS:n avulla uhkaa lisätä päästöjä. Se on ilmastotoimiksi naamioitua sääntelyn viherpesua. Saastuttajat voisivat ostaa päästöoikeuksia, jotka eivät vähennä ilmaperän hiiltä. Tässä tuhlattaisiin miljardeja ja sallittaisiin saastuttajien jatkaa vanhaan malliin.

Tarvitsemme todellisuutta vastaavaa hiililaskentaa, emme lisää tukia metsien tuhoamiselle ilmastotoimien nimissä.

Excerpt: " 'While #governments and #corporations push us deeper into #ClimateChaos, movements around the world are rising,' she noted. 'From every corner of the Earth, women leaders are coming together with solutions and strategies to defend our planet and our communities. We call on governments and financial institutions to heed their voices and ensure effective and equitable policies—from Bonn to Belém and beyond. We must rise boldly, because climate change is not waiting for politics. Our movements are not bending. We are not breaking. We are defining and building a healthy and just future for all.'

"The new call to action points out that 'last year, the world breached this threshold with global average temperatures exceeding 1.5ºC above preindustrial levels. This alarming milestone is not yet a permanent breach of the Paris agreement guardrail, which refers to long-term warming, although scientists predict that 2024 will be the first of a 20-year period reaching 1.5ºC warming.'

" 'Although the pathway is drastically narrowing, the International Energy Agency affirms that the goal of the Paris agreement is still attainable,' the publication continues. 'Scientists assert that limiting global warming to 1.5ºC will require significant and urgent action from governments and financial institutions.'

"Specifically, the coalition outlined 10 broad actions for governments and financial institutions, beginning with urging both the public and private sectors to end fossil fuel expansion and extraction, and to 'reject false solutions, such as natural gas, mega-dams, geoengineering, bioenergy, forest offsets, carbon trading schemes, nuclear energy, biodiversity credits, and carbon capture and storage.'

"The collective also called for accelerating a just transition, promoting women's leadership and gender equity, protecting the rights of #IndigenousPeoples, safeguarding #forests and #biodiversity, preserving oceans and freshwater, advancing #FoodSecurity and #sovereignty, implementing the #RightsOfNature, providing robust climate finance, and cutting off financial institutions' support for 'harmful projects and redirecting resources into climate solutions.'

"We can still enjoy fire, but we must stop burning our house down."

🚨 82 civil society organisations launch the "Beyond Bioenergy" statement.
EU #bioenergy policies are harming our climate, nature and food security.

🔥 Replacing #FossilFuels with destructive bioenergy isn’t the answer.

The EU must stop incentivising the burning of trees & crops and build truly sustainable policies that are:
✅ Fair
✅ Efficient
✅ Consistent
✅ Sufficiency-oriented

'Energy independent' #Uruguay runs on 100% renewables for 10 straight months
https://theprogressplaybook.com/2023/10/19/energy-independent-uruguay-runs-on-100-renewables-for-four-straight-months/ “#Renewables alone have powered the Uruguayan economy for 10 straight months.

Between 1 July 2023 and end-April 2024, the South American nation generated all of its electricity from #hydro, #wind, #bioenergy and #solar

Hydroelectric plants comprised 42.9% of the total mix, followed closely by wind farms at 40.6%. Bioenergy (12.9%) and solar (3.5%) accounted for the remainder.”
