Addressing concerns with magnesium oxide boards

With increased use of magnesium oxide boards in construction in recent decades, how can concerns about saturation and structural failure be overcome so products may be specified with confidence?

By 2030, biofuels are projected to emit 70 MtCO2e more than the fossil fuels they replace.

That’s the same as the emissions from almost 30 million diesel cars.

Would repost but it's an affront that he decided to be only active on the mechahitler platform.

The US federal attack on Portland has resulted in the best advertisement for a city that I have ever seen. Round-the-clock joy, community solidarity and silliness that much of the West has lost and longs for.

Gypsum production in Germany is set to plummet (first because it won’t be available as a byproduct of coal burning, later because mining will be phased out), so they are investigating clay boards as an alternative...

not really, by human scales. atm clay is mostly used from digging here and there anyway.

The UK is seriously clay-rich btw.

Michael Burchert @michaelburchert.bsky.social · 10h

Not so fun fact, we tested clay boards on timber ceilings >10 years ago, they basically worked fine but the mounting was $%&$! and the test failed. Money was gone, because funding schemes are about something else every 5 minutes.
Then we had business as usual gypsum on everything for >10 years.

WATCH: Do you have to move away from the United States in order to get a clear picture of the United States? @evanedinger.bsky.social covers the reasons he couldn’t move back to the U.S. from Europe now. Hint: #3 is about walkable cities & car dependency, but all are worth seriously thinking about.

NEW: There’s a disaster unfolding in Alaska right now. And no major network is covering it.

The remnants of Typhoon Halong battered western Alaska overnight. Homes, with people in them, have literally been swept into the Bering Strait.

At least 20 are missing. No comment from any federal agency.

You can absolutely share and like this even if you live in or work with standard building materials.
Because most of these will not be available for reno's and new builds if we care about stuff like emissions and species extinction.
It's cool that we already have alternatives to most stuff.

Fun fact: you can produce 6 straw drywall boards with the primary energy that it takes to produce 1 gypsum fiber board. For a normal gypsum board, 4 straw boards.

Keep in mind that gypsum is a finite resource in nature, unless you ask proponents of the industry.

What is drywall without "mud"/ plaster.
Global warming potential:
gypsum plaster, clay "earth" plaster technically dried, clay plaster passive solar dried.

plaster global warming potential:
gypsum plaster (high), clay "earth" plaster technically dried (somewhat lower), clay plaster solar dried (around zero, due to natural fiber content).

If you have innovative products/designs/protoypes for sustainable construction, sufficiency, resilience, regeneration, production to showcase, pls get in touch. We have pushed construction professionals worldwide with our exhibition and workshops in the straw house, and we plan to continue doing so.

Be proud of your work, if it's good work.
Good materials help with this decision.

Today, the equivalent of 100 mn bottles of vegetable oil are burned in cars every day, meaning a fifth of all vegetable oil is never even used for food.

By 2030, biofuels crops will require land the size of France, which would make it the 6th largest country in terms of arable land use globally.

Ordnungspolitik.

Ich bin schon sehr lange in dem Spiel. Lange genug. Zu lange. "Wenn du das und das erzählen würdest und das nicht, dann ..."

Es sind immer nur die Spielregeln, die zählen. Alles andere ist Ablenkung.

Die Leute sind längst überzeugt.

Wissenschaft muss lauter sein. Das vertrat ich lange. Doch ich bin mir nicht mehr so sicher. Es ist alles gesagt. Und es hört niemand mehr zu. Alle haben ihre Positionen fest eingenommen; ein Großteil auf Zuschauerplätzen. Vor allem aber: Die meisten wissenschaftlichen Akteure wollen auch gar nicht.
