Engineering Matters

In episode #221, Engineering Matters looked at a new way of manufacturing feedstocks for plastics. This approach will eliminate the use for oil products, instead making use of plant-based materials, which will also help remove carbon from the atmosphere. But eliminating the use of finite oil resources is only one part of the circular economy. This week, we wanted to take a dip into the archive, to...

The world consumes 4.25 billion tonnes of oil every year. Over half of the oil drilled out of the ground goes towards transport, but the entire sector is moving to decarbonise. However even if the transport sector no longer requires oil, many industries across the economy will still be reliant on extracting fossil fuels. In order for the world to stop drilling for oil we need to find replacements...

Buildings and the construction industry account for 39% of global carbon emissions : 28% from materials and operational emissions, and 11% from construction operations. One of the main sources of those emissions during building works, is the use of diesel generators to power heavy equipment, such as tower cranes. But this equipment only needs high levels of power for a fraction of its working day....

Can engineers help to build peace? Can the solutions engineers develop in places of conflict, contribute to the development of low carbon? They can. And Engineering Matters listeners can help with this important work. Over the past decade, many of Syria’s urban areas have been ravaged by aerial bombardment and shelling by artillery. It is a land of lives lost and cities destroyed. But in the count...

More and more of the economy is being powered by the grid and that trend will continue over the next few decades. At the same time countries are looking to reduce their reliance on coal and gas and use more renewables like solar and wind. Managing the transition to a green grid will require extensive planning and investment to ensure grids can remain reliable. A renewables powered grid will still...

The next decade will see an unprecedented level of offshore energy construction. In order to achieve the 2035 emissions targets adopted by many governments, the offshore industry will need to build thousands of turbines. Each of these must be secured by appropriate foundations and anchors, often in unmapped areas of the seabed, much deeper than those that have been used before. Achieving the pace...

Waste is an integral part of the circular economy. It is, in many cases, simply a resource that is in the wrong place. But it can also be a nuisance, an eyesore or even a risk to health. In the UK, new regulations, and changes to ways some waste handling is allowed to take place, will both open up opportunities, and impose new liabilities. The industry still makes heavy use of paper waste transfer...

When a major public infrastructure project is announced often a brand new organisation is set up that is tasked with delivering the project. These organisations can be very small and not have the experience delivering a major project that only a few people have. In the past organisations like these have hired a programme or project manager, who takes over the delivery of the project. However this...

Just over a week ago, SpaceX successfully launched one of the largest rockets ever, a key step in humanity’s journey beyond the earth. While the rocket underwent a ‘rapid unplanned disassembly’ shortly after launch, it gave the company’s engineers a wealth of data for future launches. The same company also owns the world’s largest constellation of more than 4,000 satellites, StarLink. Constellatio...

Brewers large and small are taking innovative approaches to their energy use. In Samlesbury, AB InBev has started working with Protium , who will fund, build, and operate a green hydrogen facility that will provide...

Britains biodiversity has been declining sharply over the last 50 years. We are now one of the most nature depleted nations in the world. Despite legislation and efforts to stem the tide of wildlife population decline, nothing has worked. Some Wildlife Trusts and organisations now support a more nature based approach to wildlife and land management. Rewilding is the process of helping nature retur...

Last week the UK government announced plan to ban the sale of wet wipes to deal with the problem of fatbergs in sewers. This week we’re rerunning an episode from 2019 where we venture down into the sewer system to see the largest fatberg in Europe. Underneath cities all over the UK subterranean mountains of calcified fat are gathering in our sewers as fat, oil and grease stick to baby wipes...
