The most recent developments in recycling technology

modern recycling technology

AI in Plastic Sorting

AI is already working wonders in the recycling industry, completely transforming how plastic sorts are carried out, through improved accuracy and faster workflow. Plastics are the most diverse group of materials in terms of composition, and due to this variety traditional sorting techniques have difficulty with them – meaning contamination levels are high and recycling rates low. Artificial Intelligence (AI) can discern between various materials of plastics through cutting-edge machine learning algorithms, coupled with computer vision which identifies plastic by the form that it takes. These systems are able to differentiate between different types of plastic polymer (PET, HDPE and PVC for example) allowing each type to be separated out correctly prior to recycling. In addition, AI-powered robots can work around the clock with more efficiency results meaning fewer manpower is needed and error can be eliminated that resulting to a cheaper and dependable way of sorting. The most recent advancements in these technologies improve the detection and separation of plastic polymers, increasing recycling rates while reducing contamination. More difficult applications include those with composite and film plastics (Lubongo et al., 2024).

Battery Recycling Get Pyro-Metallurgical

Pyro-metallurgical processes are vital to the recycling of batteries and their use in recovering important metals such as lithium, cobalt etc. These processes make use of high-temperature treatments that break down battery materials, allow metals to be individually sorted from the rest of the components. The strength of pyro-metallurgy is handling complex battery chemistries, leading it to be a solution that can recycle many different kinds of batteries. But the process is energy-intensive and produces emissions that have to be strictly controlled in order not cause an adverse environmental effect. Recent developments in pyro-metallurgy, for instance, are aiming to increase energy efficiency and carbon neutrality as well recovering more metal from used batteries making the recycling process greener. A green novel pyro-hydrometallurgical process for recycling valuable metals from spent lithium-ion batteries was introduced. This would enable the efficient recovery of metal such as lithium, nickel and cobalt with minimum environmental impact. (Améduri & Hori, 2023)

Recycling Fluoropolymers is Tough

Fluoropolymers are used in many industrial applications as a result of their ability to resist chemicals and not easily stick, but this very same chemical structure makes them hard to recycle. These materials are extremely stable in most natural conditions, so their recycling is difficult. Moreover, the fact that they contain atoms of fluorine can entail their breakdown to release poisons when heated at high temperatures or in other aggressive processing stages. Therefore, the recycling of fluoropolymers needs special methods from which they are offered that safely digest or make shreds with freeing them into pollution. Current work is aimed at new recycling practices to enable the effective conversion of a fluoropolymer such that environmental hazards would be mitigated. Recycling of fluoropolymers utilized in a wide range of high-tech applications is still at an emerging stage. Thermal decomposition in particular has the potential to recover these materials as shown by recent studies, and can help to alleviate environmental issues of disposal (Améduri & Hori, 2023).

Developments in recycling of lithium-ion batteries

Solving the lithium ion battery waste challenge is critical to dealing with increasing demand for sustainable energy storage solutions. Current methods to recycle batteries are obviously less effective, as they do not truly recover valuable materials in a reusable form. In addition, the development of new technologies — including hydrometallurgical processes giving access to a selective extraction of high-purity lithium, cobalt or nickel metals from spent batteries is on-going. The process of repairing and reusing the components, without disassembly down to their basic material level is also becoming more widespread. These are not just the innovations leading to higher material recovery rates, but also reducing environmental input of battery recycling itself; thus serving as integral component of circular economy. Research outlines emerging strategies for recycling cathode materials from spent lithium-ion batteries, focusing on environmentally friendly methods and efficient recovery systems. This includes new techniques such as deep eutectic solvent extraction (Duan et al., 2021).

Recycling Waste into Graphene

Earlier in the year, a few ingredients that could accelerate carbon construction of graphene were revealed. The subsequent turnround now implies any waste materials located can be put to use while improving industrial production facilities. A high interest among manufacturers and desire for low-cost methods has tuned research efforts at making finding sustainable solutions using carbon much quicker. To enable this approach means triggering multiple stage controlled construction techniques over longer time periods.Development rocks on. Graphene is a single layer of carbon atoms forming hexagonal lattices, and it delivers excellent electrical, thermal, as well as mechanical properties for deploying in multiple applications. Chemically, graphene is very simple (it consists of a single layer of atoms) but traditionally it has been difficult to make and expensive both in terms od speed energy required for production. Usually, this waste is converted to a carbon source that can be exfoliated into graphene. In addition to a more sustainable waste elimination alternative, the strategy also lowers costs of graphene production and makes it more accessible for use. This methodology presents a new beginning in the synthesis of sustainable graphene and its composites from trash through recycling technologies, leading to reduced generation of materials which can potentially reduce waste (https://pittsburghpadumpsterrental.com/).

The Logistics And Sustainability Of Batteries

Battery logistics are a key factor for the sustainable battery lifecycle from mining to recycling. By securing an efficient, environmentally friendly mode of transport for batteries to their recycling facilities and thus minimized material loss through sorting processes. Electric vehicle (EV) and renewable-energy storage-system adoption are driving demand for logistics networks that move a lot of batteries. Sustainable battery logistics includes optimizing transport path, using packaging with low environmental impact and developing reverse-logistic systems that make it easier to return end-of-life batteries for recycling. Better logistics mean that energy storage as a whole will be made more sustainable and the carbon footprint of batteries — which in many ways make or break an EV when it comes to clean transportation if lackluster charging infrastructure exists (and trust us, we hear about gas pumps going down sometimes each day!) — will directly see drastic improvements. Improvements are being made in the logistics of lithium-ion batteries (collection, sorting…) but also second-life use to increase recycling rates and keep critical materials. It is vital for charging and discharging of the batteries to work on sustainable terms (Zheng et al., 2023). In conclusion, recycling technology with advancements such as AI and alternative processing methods aid to recover sustainable material efficiency across industries.

Gold Prices Climb as Inflation Concerns Persist

bullish gold market
Gold recently reached new highs. The excitement around the precious metal continues, fueled by the approach of the first rate cuts in the United States, central bank purchases and the persistence of significant geopolitical tensions. Gold continues its crazy rise. Gold prices have gained more than 20% over the past six months but the upward movement accelerated at the beginning of March. Investors now no longer doubt that the US Federal Reserve will make several rate cuts this year. Its president, Jerome Powell, confirmed this during his press conference on March 21. The precious metal is a safe haven asset, just like American government bonds and the dollar. But it does not pay dividends or interest. Therefore, its relative attractiveness compared to other safe-haven assets increases, when interest rates fall (and vice versa).

Don’t overreact

The non-volatile component of the Fed’s preferred gauge of underlying inflation – the core index of personal consumption expenditures, or core PCE – slowed in May. This should reassure the Fed even if the overall indicator rebounded from +2.4% in January (at an annual rate) to 2.5% in February. They are not going to overreact because the data from the last two months are higher according to Jerome Powell.

Bank of America predicts gold will hit $3,000 in the next 18 months

Earlier this week, Bank of America analysts revealed that gold could hit $3,000 in the next 18 months, driven by demand from central banks and a dovish shift from the Federal Reserve. Achieving this level would require non-business demand to increase from current levels, which in turn requires a rate cut by the Fed, according to Bank of America analysts comments to investors. Current market conditions do not justify this price level at the moment, Bank of America warned, as analysts estimated (https://goldsupply.org/gold/) that a 20% increase in demand could push prices to $2,500. Previously, the bank’s analysts had predicted that a similar rise could occur in 2023.

Gold’s rise appears to be due to technical factors

The precious metal surpassed its historic record this week, to get closer to $2,150 per ounce. But this recent progression is not justified by the fundamentals. If the major American, European, or even (and especially) Japanese indices, just like bitcoin, are setting records, gold is not left out. The precious metal recently surpassed its historic record on the stock market, bringing its new peak this week to 2,185.50 dollars per ounce. The barbaric relic, as the famous economist John Maynard Keynes nicknamed it, has gained 4% since the start of the year, and is up 18.5% over one year. This recent rise in gold is, however, not easy to explain. Financial commentators also notes that this upward movement surprised market observers.

A logic on rates that does not work

For a simple reason: in theory, the evolution of gold is negatively correlated with that of interest rates. The higher the interest rates, the less theoretically attractive gold is, all things being equal. Unlike stocks (with dividends) and bonds (with coupons), gold does not produce income. Its price is consequently hit by a rise in interest rates, because it then becomes less and less interesting to invest your money in gold rather than investing it. However, although there is unanimous agreement on the idea that central bank key rates have reached their peak, the market has been forced, in recent weeks, to significantly revise its expectations of rate cuts. For example, investors are counting on a first cut in June from the American Federal Reserve, when the market was still banking on March at the end of 2023. The number of rate cuts has also been largely revised downwards, and the some economists are even banking on no cuts this year from the Fed (). The velocity and the speed of the rise was very sudden, very rapid. There doesn’t seem to be any compelling evidence. Physical demand for coins or bars may be stronger than expected, with analysts raising the possibility that Chinese consumers bought gold during the Lunar New Year festivities to hedge against turmoil in the stock and real estate markets. Commodities strategist consider that the risk of a correction on global equity markets could also have boosted demand. Perhaps also the purchases of certain major central banks may have provided a little support. The People’s Bank of China, the country’s central bank, announced that it had increased its gold reserves for the sixteenth consecutive month.

Technical elements

UBS (https://www.ubs.com/uk/en.html) questioned the rise in gold in a note: even if we were among the few to promote the idea that gold could progress significantly this year on the basis of better fundamentals including demand from the technology sector (https://www.hiddennolonger.com/new-technologies-at-the-service-of-the-environment/), the account is not there in the last few days from a fundamental point of view. Some banks also point out the theoretical inconsistency of the rise in gold prices at a time when the monetary markets are integrating key rate cuts by the Fed of 86 basis points, or 0.86%, compared to 117 basis points just a month ago. Gold is therefore clearly influenced by other elements. They believe that more technical factors have been at play recently, with prices having crossed key resistance levels, thanks to buyers oriented towards the short term. But increasing attention to the US presidential election, continued central bank buying and still relatively modest speculative positioning indicate that this rally still has a bright future ahead of it in the medium term, particularly if ETF purchases are recovering, generally following the trend. UBS talks about the medium term. In the short term, the Swiss establishment recommends waiting before positioning itself on the precious metal in order to avoid disappointments. The bank suggests watching for a return of gold to around 2,000 or 2,050 dollars before strengthening a long position. The establishment also suggests looking at mining groups extracting gold rather than immediately buying the raw material itself. If the bank does not give a name, we can cite as examples the Canadian Barrick Gold or the British Fresnillo.

New technologies at the service of the environment

recycling mobile phones

So that the worst dystopias and cyberpunk atmospheres do not become a reality, ecology must be placed at the heart of high-tech. Green-washing, based on shells recycled from devices containing mercury, lead, cadmium and other substances that we advise you not to eat through a straw, may not be enough. But then, what to do?

No more abundance, it seems time is for sobriety. Once the announcement effects and declarations of intent have passed, we must question our uses and think better about our electronic equipment, both for ecological and economic reasons, in Texas and elsewhere.

To do this, let’s start by knocking down an open door: the most environmentally friendly material is the one that is not produced. Once a gadget lands in the hands of a user, its ecological footprint can no longer be counted in negligible quantities.

However, these gadgets provide excellent services, we can therefore legitimately question the durability of their products before considering them obsolete. And if the primary use no longer satisfies you, is it possible to find another use for them? Finally, there is the question of resale for a second life or proper recycling.

Incompressible footprints

Embodied or embodied energy is the sum of the energies necessary for the product during its entire life cycle. This goes from the extraction of raw materials, manufacturing, packaging, distribution, transport, sale, use, maintenance and recycling.

A parameter that must be kept in mind when buying, for example, this microphone in which the youngest of the family will have vaguely sneezed three times before it ends up in a recycling bin. Does this experience feel like lived experience? This is normal, but we are consumers who should not be stigmatized in any way. Raising awareness and supporting this transition proves to be much more constructive.

Embodied energy therefore already has a heavy ecological impact in itself, but there is no question of putting it solely on the shoulders of the end customer. Let’s put aside planned obsolescence, known to all, to focus on the subject of device updates. This is a particularly notable fact for Android smartphones whose manufacturers do not fail to offer us a host of models each year, but are less valiant in software monitoring.

While Android 14 has been available in final version for several months, only 13.3% of terminals are on Android 13, 27% on Android 12 and still almost a quarter on Android 11. Dispersion is much less important at Apple, but the company is the only one to offer terminals with iOS.

We can also blame all market players for the temptation of entry-level equipment. When it comes to computers or small electronic devices, being inexpensive requires cutting back on power, quality of materials and/or services. It still happens too often that memory and/or storage are soldered to the motherboard, preventing any future development.

These devices, which are impractical or show signs of fatigue too quickly, are then quickly discarded. Obsolescence is not planned here, it is almost consented to and fueled by sophisms such as “in two years it will no longer be worth anything”, “these things never work for long”, “for the little that I’m going to use it”, etc.

Of course, not everyone has the means to buy new high-end products, which is why it is important to consider repairs, the second-hand market, etc. Manufacturers offering low-end products en masse are much more reprehensible.

Far be it from us to resort to catastrophism, on the contrary. Trends are beginning to emerge in terms of recycling and life extension. Green IT, for example, consists of imagining sustainable and eco-responsible IT across all links in the chain. This ranges from eco-design, which consists of optimizing environmental or social performance during the development of a product, to responsible use of our technologies. Recycling is part of this, but it also covers, for example, organizing a video conference rather than moving entire teams.

The public authorities have also taken up the subject with laws proposing in particular indices of repairability and durability, the provision of spare parts for at least five years, more transparency on waste management, followed by a host of measures to reduce the environmental footprint of digital technology.

Technology and ecology

Let’s keep our “old” products. Let’s admit it, it is impossible to part with our PCs and/or other mobile devices since, already, it would be difficult to consult Next INpact calmly. In terms of technology, the question is therefore not to go back, but to move forward differently.

We return to our uses and the way in which we can reduce our impact on the environment. A drop of water in the ocean? Far from it, in terms of ecology there are no small savings, because if your carbon weight loss treatment seems negligible it is part of a necessary societal change. Let’s start by kicking off the good old Moore’s “law”, adapted several times to finally evoke something that doubles every 18 months.

Our computers have long been obsolete within the first six months of purchase, but many users still say that these devices are destined to be scrapped after two or three years. As for laptops, it is customary to explain that a battery can perform 3,000 charge cycles and therefore last three to five years depending on use. The veracity of this information does not matter, a battery must simply be able to be changed and at a reasonable price. Requiring the production of spare parts for at least five years is therefore going in the right direction.

And this also applies to the mobile market, which users keep on average between 23 and 37 months while the mechanical lifespan of these devices is around seven at ten years provided that the battery can be changed. Unfortunately the software part will not follow… There is still a way to go. The second life of our equipment must also be taken into account ecologically.

Technology and ecology

If you have the skills, switching an old PC to Linux to avoid leaving it prey to viruses on non-updated Windows is a good way to extend its lifespan. The second-hand and reconditioned market is also experiencing strong expansion, whether on sites such as Back Market, Afbshop, Rakuten, joined by large well-established brands.

We must obviously not forget organizations which, in addition to ensuring a second life for our devices, strives to reduce the digital divide. Linux distributions have even specialized in this market. Do not hesitate to contact local associations or participate in install parties to get advice and help on site. However, pay attention to another point: electricity consumption. Recent processors and GPUs often display a much better performance/consumption ratio than previous generations. If your old equipment has no other hope than ending up in the dumpster, then you must ensure it is recycled.
