The Problem Of Waste Plastic And Why Pyrolysis Oil Might Just Contain The Answer
The title of this post, is the same as that of this article on the Chemical Engineer.
These three paragraphs introduce the article.
One of the few technologies that can break down unrecyclable post-consumer waste plastic, pyrolysis is fast becoming a potential recycling route for companies trying to reduce their waste output.
The world produces around 450m t/y of plastic, but only 9% is recycled, with most waste ending up in landfill. Pyrolysis, which involves heating the plastic at extremely high temperatures in the absence of oxygen, breaks down the molecules to produce pyrolysis oil or gas. The oil can then be used to develop new products.
George Huber, a professor of chemical engineering at the University of Wisconsin-Madison, is leading a research team that is investigating the chemistry of pyrolysis oil and its use in polyolefin recycling.
This is a quote from George Huber
Waste plastic should be viewed as a resource we can use to make plastics and other chemicals. We should not be landfilling or burning it, we should be reusing the carbon in waste plastics.
I very much agree with what he said.
These are my thoughts.
Pyrolysis
The Wikipedia entry for pyrolysis starts with this paragraph.
The pyrolysis (or devolatilization) process is the thermal decomposition of materials at elevated temperatures, often in an inert atmosphere.
This paragraph describes the technique’s use in the chemical industry.
The process is used heavily in the chemical industry, for example, to produce ethylene, many forms of carbon, and other chemicals from petroleum, coal, and even wood, or to produce coke from coal. It is used also in the conversion of natural gas (primarily methane) into hydrogen gas and solid carbon char, recently introduced on an industrial scale. Aspirational applications of pyrolysis would convert biomass into syngas and biochar, waste plastics back into usable oil, or waste into safely disposable substances.
I came across pyrolysis in my first job after graduating, when I worked at ICI Runcorn.
ICI were trying to make acetylene in a process plant they had bought from BASF. Ethylene was burned in an atmosphere, that didn’t have much oxygen and then quenched in naphtha. This should have produced acetylene , but all it produced was tonnes of black soot, that it spread all over Runcorn.
I shared an office with a guy, who was using a purpose-built instrument to measure acetylene in the off-gas from the burners.
When he discovered that the gas could be in explosive limits, ICI shut the plant down. The Germans didn’t believe this and said, that anyway it was impossible to do the measurement.
ICI gave up on the process and demolished their plant, but sadly the German plant blew up.
I would assume we have progressed with pyrolysis in the intervening fifty years.
University of Wisconsin-Madison
The University of Wisconsin-Madison is a top-ranked American University and is part of my daily life, as the Warfarin, that stops me having another stroke was developed at the University in the 1940s.
Conclusion
The article is a must-read and I feel that my past experience says, that George Huber and his team could be on to something.
I wish them the best of luck.
A Manifesto For Liverpool City Region
The title of this post is the same as that of this document from the Heseltine Institute of Public Policy, Practice and Place.
The Heseltine Institute for Public Policy, Practice and Place. describes itself like this on its home page on the University of Liverpool web site.
An interdisciplinary research institute focusing on the development of sustainable and inclusive cities and city regions.
The main sections of the document are as follows.
- How Can We Reduce Health Inequalities?
- How Do We Meet Our Net Zero Goals?
- How Can We Address The Cost Of Living Crisis?
- How Can We Deliver Sustainable Mobility?
- How Can We Address The Challenges And Meet The Opportunities Of Artificial Intelligence?
- How Do We Build Enough New Homes In The Right Places?
- How Should We Care For The Most Vulnerable In Society?
- How Can We Maintain A Vibrant And Inclusive Cultural Life?
- How Do We Restore Trust In Democracy?
These are nine very important questions and the document is worth a good read.
Sumitomo Mitsui Trust Bank Makes Substantial Investment In Australia’s MCi Carbon
The title of this post, is the same as that of this article on the Carbon Herald.
This is the introductory paragraph.
MCi Carbon, an Australian clean technology platform revolutionising the carbon recycling industry, proudly announces the addition of esteemed Japanese investor, Sumitomo Mitsui Trust Bank, to its investor roster. This significant investment from the Japanese giant, with assets under management totalling $617 billion marks a pivotal moment in MCi Carbon’s journey towards global leadership in carbon capture and utilisation and underscores the growing international recognition of Australia’s role in the transition to a zero-carbon world economy.
I believe that MCi Carbon, will be a very successful company.
I first wrote about this company in March 2021 in Energy Minister Angus Taylor Launches $50 million Fund For Carbon Capture Projects.
What Happened In Moscow Today?
I woke up this morning and deliberately stayed at home to watch Navalny’s funeral, as logic told me something serious would happen.
The day started how I would have expected, with hundreds of police lined up ready to arrest those who showed the wrong attitude or laid flowers.
Putin’s parents lost both their first two sons because of illness and WW2. A friend of mine also lost two older brothers and his mother was so overprotective, that it seriously affected his mental health. Later in life, he retrained as a psychotherapist to excise his personal demons.
Putin also has the problem, that his father was a member of an NKVD destruction battalion (think Katyn!), so I suspect he had a good line in bedtime stories for his son.
I wonder if something unexpected happened today.
- Did the sight of Navalny’s mother and her grief, awaken Putin’s memories of his own mother and he backed off?
- Or did the police on the ground, take a words will never hurt us attitude to the crowd? It might have helped, that a proportion of the police probably held some of the same views as Navalny.
I have some further thoughts.
The Grosvenor Square Protests Against the Vietnam War
I can find two references to these in this Wikipedia entry, which is entitled List Of Protests Against The Vietnam War.
- July 3, 1966. A crowd of over 4,000 demonstrate outside of the U.S. Embassy in London. Scuffles break out between the protesters and police, and at least 31 people are arrested.
- March 17, 1968. In London, a violent protest not supported by the Old Left leads to over 300 arrests.
A policeman friend of mine, who was on duty, told me that trouble is defused, if the police have common ground with the demonstrators.
The Number Arrested Today In Moscow
This was given as six, which is consistent with the number arrested at non-violent protests in London against the war in Gaza.
My Experience Of Moscow Police
In September 2001, I went to Moscow to see Ipswich beat Torpedo 2-1. See More…
After the match, the police were looking at the Ipswich supporters, as if they wanted a fight. So I broke ranks and offered both hands to the guy, who looked to be in charge. He shook my hands, gave me a hug and a smile and everybody walked to the coaches.
Nobody wanted a fight, so one didn’t happen.
My Experience Of Minsk Police
In October 2008, I went to Minsk to see England beat Belarus 3-1. See More…
A lot of the England fans were worried after being badly treated by Moscow police, the year before.
But there was no need to worry, as the Belarus Police were dressed to be friends and there was no trouble.
Conclusion
Whatever happened today could be significant!

ICE Report Shows Majority Open To Net Zero Changes
The title of this post, is the same as that of this article on The Engineer.
This is the sub-heading.
A new report has found that a majority of the UK public is amenable to the behavioural changes needed to hit the country’s net zero targets.
These two paragraphs summarise the findings of the report.
Published by the Institution of Civil Engineers (ICE) and the All-Party Parliamentary Group on Infrastructure (APPGI), the report was based on a survey of 1,000 respondents. It found that 57 per cent were open to change, with 23 per cent described as net zero enthusiasts who were likely to have already altered their behaviours, and 34 per cent wanting change, but feeling they needed further empowerment to achieve it.
However, there is far from universal agreement when it comes to behavioural change around climate action. The report found that 30 per cent of people were ‘reluctant followers’, largely acknowledging that the UK must act on emissions, but not feeling personal responsibility for that action. This segment will likely only change their behaviours if forced to do so or seeing a majority of others doing it first. Finally, 13 per cent of those surveyed were classed as ‘net zero resistors’, people who don’t believe action is necessary and have no intention of doing so.
Summing the figures up gives us.
- Net-Zero Enthusiasts – 23 %
- Wanting Change – 34 %
- Reluctant Followers – 30 %
- Net-Zero Resistors – 13 %
All politicians should be forced to read the full report.
What Would I Need To Do To Achieve a Personal Net-Zero?
My circumstances probably cover a lot of people.
- I am a widow living alone.
- My house is well-insulated with solar-panels on the roof, but heated by gas.
- I don’t have or need a car.
- I do nearly all my shopping by public transport and carry it home.
- When I go away in the UK I use trains.
- If I go to Europe, I either go or come back by train.
- I am coeliac, which means I need to eat some meat to stay healthy.
My largest carbon-emitted is probably my house, but it would be unsuitable for most current solutions.
I would put myself in the Wanting Change group, but I could move to a Net-Zero Enthusiast, if the right technology came along.
- I have seen one bolt-in electric replacement for by boiler and when the right one arrives, I’ll probably fit one.
- An affordable battery to work to with my solar panels and also allow me to use Off Peak electricity would be nice.
- As I’m coeliac, I tend to buy in the same food each week from Marks and Spencer to eat in. I might be able to cut my carbon footprint by getting Ocado to deliver. Especially, as some deliveries seem to be bike.
- If TfL decarbonised the bus, that I use most days to and from Moorgate would that lower my carbon footprint?
I suspect the largest amount of carbon outside of my house’s heating, that I’ll emit, will be tomorrow, when I take a train to Newquay.
How Do We Convert The 13 % Net-Zero Resistors?
The recent protests by French and Belgian farmers indicate, that these farmers are probably in this group. And there are other forthright groups!
The only way, that they’ll be converted, is if technology allows them to earn the same amount of money and have the same outgoings, as they do now!
City Of London: Skyscraper As Tall As The Shard Planned
The title of this post, is the same as that of this article on the BBC.
This is the sub-heading.
A skyscraper the same height as The Shard is being planned for London.
These are the first three paragraphs.
One Undershaft would reach 74-storeys, according to revised plans submitted to City of London Corporation.
The amended proposals include a new stepped design instead of a previous rectangular shape, with the building initially receiving approval in 2016.
A public consultation has taken place on the proposals, which would see London’s highest public viewing gallery at the top of the skyscraper.
This Google Map shows the site.
Note.
- One Undershaft is indicated by the red arrow.
- The Gherkin is next door.
- This web page shows the architect’s visualisation.
I don’t think it will a sore thumb like The Shard, which intrudes into so many London views.
New British Steel Rail Stocking Facility Will Boost Network Rail Supply Chain
The title of this post, is the same as that of this article on RailUK.
These four paragraphs outline the new facility and how it will work.
British Steel is building a new £10 million rail stocking facility, the biggest of its kind in the country.
The facility, at the company’s Scunthorpe site, is scheduled to be completed this summer and will stock around 25,000 tonnes of 108-metre finished rail.
The investment is part of our British Steel’s strategy to support the supply of 56E1 and 60E2 section rails for Network Rail, ensuring there is rail stock readily available for its supply chain.
Rails stocked in the new facility will all have undergone the stringent testing and quality assurance checks required to meet the specification to allow immediate dispatch or welding into 216-metre lengths to the customer.
With all the gloom in the steel industry, It’s good to see someone investing in new facilities.
The Moths Have Eaten My Long Johns
When I took the pictures in A Sleigh Ride, and at probably most of the other posts from my trip to Poland in Winter, I was wearing an expensive pair of Merino long johns.
I have tried to wear them in this cold snap, but they have been eaten by the f**king moths.
Still at least I don’t feel the cold badly.
That’s probably because I was brought up in Cockfosters, which is the coldest place in London.
Moorgate Station’s Soldiers Are Now Painted
The City of London’s soldiers outside Moorgate station have now been painted.
But the plastic barriers haven’t been removed yet.
It looks like the station entrance could be finished soon.
If you want a bollard like this for your drive ATG Access make and sell them.
