“No Bricks, No Glass, No Cement” – What Net Zero 2050 Demands According to Government-Funded Report

Reposted from the Daily Sceptic


No bricks, the walls and foundations made of compacted earth, cement made from clay and glass scavenged from demolition skips are just some of the construction changes needed to comply with Net Zero by 2050. The latest paper from Government-funded U.K. FIRES looks to “minimise new construction”, and notes the shape of the urban environment will change, allowing for “denser living and reduced transport needs”.

The latest U.K. FIRES paper seems to have slipped out quietly at the end of last year and has to date attracted little publicity. But the group, which comprises a number of academics led by Cambridge engineering professor Julian Allwood, made headlines around the world recently with previous work noting that all flying and shipping must stop by 2050, beef and lamb must be banned, and only 60% of energy will be available to cook food and heat homes. The group, which receives £5 million from Government sources,  is interesting because it bases its recommendations on the brutal, and many would argue honest, reality of absolute Net Zero. It does not assume that technological processes still to be perfected or even invented will somehow lead to minimal disturbance in comfortable industrialised lifestyles. It could be further argued that its continued existence and pronouncements are important, since they highlight the dishonesty and deceit that surrounds many other Net Zero promoters.

U.K. FIRES sees the future of construction based on stone, earth and timber, along with components “reused and repurposed” from demolition. Recycled steel, cement and bricks can be used, although this will be “constrained” – rationed might be a better word – by a supply of “non-emitting electricity under high demand”. Transformational construction changes will take longer to achieve, state the authors, but the U.K.’s ambitious target of a 45% reduction in emissions by 2030, “can only be achieved through reduced material demand”.

Building without bricks is an interesting suggestion and over two billion are currently produced each year. But bricks require high firing temperatures, and the enormous cost of Net Zero energy makes them uneconomic to produce. Cement also requires energy to make but it can be mixed with calcined clay. Nevertheless, calcined clay is also energy intensive and can only supplement 50% of Portland cement. “As a result, the mass low-cost consumption of concrete will no longer exist,” the authors note. Together, bricks and cement generate annual turnover of over £10 billion. Rammed earth, which can be used for foundation screeds and walls, is said to be a proven and potentially zero emission alternative, “which can utilise abundant local materials”.

Glass looks to be a complete no-no, with production requiring temperatures of 1,700°C and producing additional process emissions which cannot be avoided by electrification. Only recycled glass seems to be acceptable for the absolutist authors, so the need for complete circularity, “will somewhat constrain the supply of glass”. However, add the authors helpfully, this will “encourage direct re-use and reconditioning of glass panels from demolition sites”.

Steel is widely used in modern construction due to its large load-bearing properties. Around the world, recycled steel accounts for about a third of current production. To have zero emissions from producing steel relies on energy-intensive carbon capture and storage technology, which the authors observe, with their customary honesty, “is unlikely to be economical by 2050”. In the U.K., 85% of steel is already recycled, and it is explained that the Net Zero transition will heavily restrict its supply. Recycling of aluminium is said to be the “preferred zero emission compatible pathway”, and this will lead to “higher prices due to a restricted supply of the material”.

Timber is also constrained by carbon emission production processes, and sustainable supply is limited by forests unable to rapidly match increased demand. The construction industry accounts for a seventh of all plastics used in the U.K., but needless to say, there are problems. Although plastics play a vital part in insulating buildings – plastic doors and windows can be sealed much more effectively than wood – the authors note that they will become “increasingly constrained and expensive to produce”.

At times, your correspondent might be accused of exaggerating the effects of Net Zero, a collectivist political agenda increasingly divorced from the reality of modern living. But phrases such as “economic and societal breakdown”, and “mediaeval mud huts within 30 years”, would appear to be increasingly justified. Look at what is actually being said and done. In the Brecon Beacons, a new college called Black Mountains (BMC) is promoting its new climate breakdown university degree. One short course offered by this seat of learning is ‘Composting Toilets‘. This will serve as a “high quality exemplar” that will inform the design and building of some of the “potential future facilities on the BMC campus”.

As well as learning, this new college is obviously a seat of great easement as it moves effortlessly to a Net Zero future. The World Economic Forum says you will eat bugs and own nothing – to this might be added that you will crap into a hole in the ground, and, of course, be happy.

The table on page 6 indicates very careful technical sorting of scrap metal in order to maintain alloy formulations. What this means, but is left unsaid, is the length of time required to make reasonable stores of such metal by sorting scrap for a electric furnace charge. Really, specialty alloys are hardly possible without some primary iron.

People have no idea the extent to which things will have to be redesigned and reformulated. Like rising on the learning curve from prehistory, practically.

Absolutely. People have no understanding of what is termed “industrial heat” Much of what is made in industry cannot be made using energy generated from renewables.

It is difficult if not impossible to build things to a standard that is acceptable. The greens just keep banging on about net-zero and de-carbonization. In the real world aligning EVERY industrial process with renewables is impossible. Not least due to the cost.

The labor costs of reclamation, sorting, preparing materials for re-use or re-purposing are much higher than lowest cost options. Think labor costs alone.
Are costs adequately recognised in the “green” mandates? Of course not.

Show a graph of “diminishing returns, escalating costs/unit” .
Also show one of “cost vs warming avoided” (delayed!).

Would the public understand, probably not.

But the self-interested “greens” will still take the money and run.
Unaccountable as usual.

Continue to describe what mandated “net zero” will have on the public’s standard of living.

Yes! I was always a fan of Buckminster Fuller as a source of creative if not always practical ideas. He was a proponent of building people-spaces with ever-fewer resources, derived almost entirely from materials “mined” from previous less-efficient structures. Lots of good ideas there, but lots of gotchas are always lurking in the details. An interesting aside: for several generations, much rebar (reinforcement for concrete construction) in the US was made from recycled railroad track.

I stopped taking this seriously when I got to UK. The word Germany has the same affect.

In the US, when I see NYC, Washington DC or Califonia I do not think these are serious people.

I am retired now but when I entered the work I thought we had some serious problems. However, my dad entered the work force during the depression by joining the USN. He was stationed at Pear Harbor in 1941.

The depression, Spanish flue, and WWII were serious problems.

One of the problems I worked on as an engineer was spent nuclear fuel rods. The US was on a path to have a geological repository accepting spent fuel by 2012 but POTUS Obama refused to follow environmental regulations passed by congress.

It is now 2023 and spent fuel rods are not a serious problem. Of course it never was.

Net Zero is a solution for a non serious problem. My goverment and other governments will spend lots of tax money to just to fail.

That is ok because we are rich and it is not a problem

By 2040 or 2050 these silly people will find some other crisis to not be serious about.

So I think the world is doing fine. Of course I am not heating my house depending on Putin.

All these modern items require significant amount of energy that renewables just can’t economically or reliably supply.

There is a production problem, it’s been building for quite some time now and we now witness its ‘flowering’
The problem is, and it’s the root of nearly all contemporary problems ##, is that the production & consumption of Sugar is ramping up – while production/consumption of its antidote is being (increasingly) forcibly ramped down.
Sugar is poison, very few critters on this Earth can exist by eating it to exclusion of everything else, even before it is devoid of all the trace-elements and micro-nutrients that critters need.

Basically, the production of Starvation is ramping up – and that is a (the) problem

## Sugar is at the same time, the solution to all our problems.
i.e. When confected into Comfort Food & Alcohol, it dissolves away all our problems.
For a few hours
Then we need to eat more.
And because more and more is being produced and is just begging to be eaten:
Ta-dah: “Everything has never been better

Rather similar to how everyone ‘knows’ what Trapped Heat is and it’s impossible to convince them that heat is untrappable, how do you persuade anybody that Fat People Are Starving?

Sugar is not poison it is fuel. Human bodies are heat engines and we need energy. We convert sugar to CO2 which is also not toxic. We store excess energy in the form of fat in our bodies. We also need shelter to conserve the amount of energy we need. We need cement.

During the last glacial maximum (LGM) human survived by eating animals who were good at storing fat.

So what about the NGM or next glacial maximum?

When I go to the doctor, some young person tells me I need to loose weight. So what is the right weight? For that matter what is the right temperature for the planet?

The people writing these reports should be ignored as they have not thought about how these stupid restrictions if implemented would destroy their country .
To put it bluntly they have not but their brains into gear before the write this crap.
The first major mistake that they have made is to believe the lies that some scientists are spreading without any proof .
The world has warmed 1.6C since 1850 at the end of the Little Ice Age and it is still not as warm as when the Vikings settled in Greenland .
There are many other facts that prove that our present slightly milder temperatures have occurred many times in the past .
As for them calling for the banning of farmed animals because of their methane emissions is absolute stupidity.
All forage that farmed animals consume has absorbed CO2 from the atmosphere .
A very small amount of methane is expelled during digestion are due to methode microbes in the animals stomachs which break down cellulose and rapidly multiply ,moving through the animals digestive systems and are then absorbed as food .
The process is a closed cycle and not one atom of carbon is added to the atmosphere.
Scientists know that methane will never warm the world as methane is less than 2 parts per million in the atmosphere were as water in very cold air can be as low as 10 ppm ad up to 50,000 ppm in humid tropical air.
This must be a joke ,the end of the world is nigh because methane is close to 2 parts per million in the atmosphere .
What about water vapour which overlaps the same band widths as methane with warm humid air as high as 50 parts per million with even freezing dry air at 10 parts per million .
Have these over educated people never learnt a few scientific principles and to question what they are taught ?.
Asia countries are ignoring these rubbish reports ,they are using far more more coal than was used in all countries in the world in 2009 .
Any country that takes notice of this report will destroy their standard of living and push their populations into poverty .

That’s happening here in Woke-achusetts. Housing costs are skyrocketing. Lots of reasons including much higher energy costs, much good land is now being covered with solar “farms”, greedy trade unions, other land being locked up for parks, a decline in the northeastern timber industries because the greens hate that industry, very high state and local taxes (thanks to greedy teacher unions), excessive regulation of the construction industry, etc. I’ll soon have to stop calling it Woke-achusetts and call it Broke-achusetts. My home value is going up too- even here in rural central part of the state, but the local taxes are so high I can barely afford them- so I’m considering moving to a lower cost of living part of America. I don’t think you can buy any home in the Boston area for less than half a million dollars. The state’s population hasn’t grown in my entire 73 years living here. I expect it’ll soon stop dropping.

Steel is like plastic, in a very lot of ways actually if you think about it.

But significantly here, it is not recyclable
Just like plastic, every time it goes round the loop it gets more and more contaminated with ‘other stuff’ and it then becomes unusable. It ceases to have the characteristics and properties you need.
It’s already happened, recycled steel that’s come via China(the only folks who do any amount of recycling) is garbage.
You cannot cut it, it is brittle and cracks if you try to bend it, it’s impossible to weld consistently. Once you find a setting, rods, flux and technique that does work, the next batch you use is different.

Do The Planet a favour: Recycle all old steel into artificial reefs, just offshore and in no more than 100 metres of water.
Fishes, plants, seaweeds and Gaia will thank you from the very bottom of their little hearts. Let’s have some Real Global Greening: instead of the fake fantastications coming from NASA, their Sputniks and magical thinkings by folks who haven’t a clue how plants/bacteria work/grow/live and depend upon for sustenance.

Why not recycle bricks?
I went to visit the allotments in my (new) local village and got chatting with a long time native. A practical fellow with an epic array of small, old, antique but still functional farm-tools and machinery. Like meeting a long-lost brother.
Also he had piles of ‘stuff’ – some of which contained the bricks/blocks used for ‘Block Paving’
I said that my new house had lots of those for its driveway and also in the garden.

He recounted the tale of the ‘pedestrianisation’ of the local town centre – how all the asphalt roads and concrete pavements were ripped up and replaced by these (concrete) Paving Blocks.
Cars were still (only) allowed in at certain times

After not very long, it was realised what an epic blunder this was. Maybe in combination with the geography (3Metres AMSL) and certainly the soil-type round here, the blocks didn’t work.
They sank, they heaved, they flooded, they were slippery & dangerous, weeds and grasses simply loved all the crevices between them (that’s the fertile soil for you) and it all became just a mess and a nightmare

So they were all, barely 5 or 6 years old, pulled up and sent to a crusher

Five Hundred Thousand of them

Doncha just love Bureaucracy.

“Timber is also constrained by carbon emission production processes, and sustainable supply is limited by forests unable to rapidly match increased demand.”

The greens, at least in America, are now against cutting any trees- which they claim must be left to sequester carbon. As to supply, it can be much higher if more forests are well managed to produce timber. Many forests in America are severely degraded but with “improvement harvests” really grow far more high quality timber. And, the carbon footprint of wood products is far lower than cement, steel and other construction materials. Not that it matters, in my opinion.

Actually it would be much worse than the Dark Ages. A contributor called Stephen Finder over on Manhattan Contrarian pointed out that the Dark Ages were a long period of stable social stratification that evolved over centuries until capitalism and the Enlightenment stirred things up. You couldn’t just will it back into existence when the lights go out.

Under feudalism, everyone knew their place in the hierarchy. They believed absolutely in a God that would punish them in the afterlife for misdeeds in this one. (Although they could avoid damnation by confessing to the priest before being executed.)

King Alfred the Great gradually exerted his power over dukes and warlords and united the Anglo-Saxon realm under himself (England I’m referring to) by defeating his competitors and usurpers in battle and executing them. He and all after him ruled by divine right, backed up by the Roman church who knew he would enforce tithing to it. There was a well-defined social construct glued together by king and church because the church said God was the source of the king’s power and that power passed theologically to his first-born son. No argument other than from people like William the Conqueror with the ability to invade, and before him waves of Danish sea robbers who actually occupied London for a time. (Hence the Dane-geld.) Henry VIII’s fight with the Church in the 1500s was crucially important even though it seems like a silly sideshow to us today. It is really the crowning moment that ushered out the Dark Ages.

The Dark Ages cannot be simply recreated when society collapses from energy poverty. Instead it will be all against all because there will be no recognized central authority, no reason to obey police officers or tax collectors or respect the decisions of law courts and no reason for interlopers to leave your property except by threat of superior arms and ruthlessness. It would take 500 years to re-create the feudalism of say, Henry II (England’s greatest king in my opinion.)

April 30, 2023 6:04 am

This NewWorld concept that stacking people into compressed cubic urban areas will reduce transportation costs, monetary and energy-wise, is a huge canard. The lowest processing/transport cost will be enjoyed by the exurban settler with 10 acres to grow vegetables, chickens, and maybe a very few pigs/goats/cows.

Want to add a new bedroom? Rent a portable sawmill, cut down a few of your trees, and build away, maybe over a foundation of treated wooden piles from a local sawmill or maybe rammed earth with a thin slab (1 1/2″) of dry-pour concrete using water from your own well. Need protein for a meal? Grab some eggs from your chicken shed. Need fertilizer? The chickens/pigs/goats will provide.

Or just build a few nuclear power plants and leave everything else as it is. But where are the excess profits in that?

But bricks require high firing temperatures, and the enormous cost of Net Zero energy makes them uneconomic to produce.”

Actually you can make bricks using methods first developed by the Mayans and their ancestors. See geopolymers:


Africa is already doing it. In Malawi TNO is making red bricks for construction without any firing at all.

As you can imaging, the cement companies are freaking out over this resurgence of a forgotten technology. It is reported to be 1/5th the cost of cement in its minimalist form. Very high performance geopolymers are also available that are fired like ceramics.

Another material is phosphate bonded high alumina minerals though the resources are far smaller. These include an aluminum dihydrogen phosphate bonded alumina (say, above 33%) which forms very strong refractory material without firing. Crushing strength 14 MPa. Viable 2 story homes require 2 MPa, preferably >4 MPa.
