Cyprus Schools Turn Cooking Oil Into Biofuel in Award-Winning ‘Frying Pan’ Initiative

In a move that’s earning Cyprus international praise, schoolchildren are playing a key role in turning used cooking oil into biodiesel. The “Tiganokinisi” or “frying pan” initiative, which has been integrated into the country’s national curriculum since 2018, is revolutionizing the recycling process, one bottle of oil at a time.

With over 80,000 students engaged annually, the project has schools acting as collection hubs for used cooking oil. The oil, sourced from homes across the island, is then filtered and transformed into biodiesel, tackling a global environmental problem: the disposal of millions of liters of cooking oil that often end up clogging drains, contaminating water supplies, and causing landfill fires.

Xenia Loizidou, chair of the AKTI Project and Research Centre, which coordinates the initiative, explained the scale of the challenge: “The logistics are huge to collect this half-litre of cooking oil from each of our houses.” Despite the challenges, the program has already managed to capture about 10% of Cyprus’s annual 2,000-tonne cooking oil waste.

The project has also proven to be an educational goldmine. Students not only contribute to recycling efforts but are also given a say in how the proceeds are spent—funding green initiatives like photovoltaic panels, water fountains, and aromatic gardens in their schools. Over €550,000 has been allocated for these projects since the program’s inception.

In 2021, U.S. energy giant Chevron stepped in to fund the mobile science laboratory that travels to schools across Cyprus, furthering the program’s reach. “We quickly realized this was a great fit for us,” said Kristian Svendsen, Chevron’s regional manager for Egypt and Cyprus. The initiative has now visited over 500 schools, spreading awareness of both recycling and renewable energy.

With its blend of environmental activism, education, and community involvement, “Tiganokinisi” has garnered attention worldwide, winning accolades from the European Commission for social innovation and from the Global Education Network Europe for excellence in global education.

This pioneering initiative shows how Cyprus is stepping up to tackle waste while teaching a generation of students that “waste” can have value—and that value can help power the future.

Anthropic’s Opus 5.5 Arrives With Lower Costs, Faster Performance And Sharper Safety Guardrails

Anthropic on Tuesday unveiled Opus 5.5, its latest flagship model and, by the company’s account, a new state of the art in coding and knowledge work.

Opus remains the top tier in Anthropic’s three-model Claude family, positioned above Sonnet and Haiku, which serve the middle and entry-level segments respectively. The company says the new release not only outperforms the larger Fable model on several benchmarks, but also completed a number of informal tasks that Fable could not finish.

A More Efficient Frontier Model

One of the most notable changes is economic, not just technical. Anthropic says output tokens for Opus 5.5 will be priced at $20 per million, down from $25 for the previous version. Other usage metrics have also declined, and the model is faster to run, reflecting lower compute requirements to serve it.

That matters because model economics are increasingly central to enterprise adoption. In practice, a more capable model is only part of the equation; speed and cost often determine whether it can be deployed at scale across software development, research, customer operations, and internal knowledge workflows.

Sharper Communication, Less Jargon

Anthropic says the update also changes how Opus communicates. The new model is less likely to lean on jargon and more likely to lead with the most important information first. For business users, that is more than a stylistic adjustment. It improves readability, reduces friction in decision-making, and makes AI output easier to use in executive settings where time is scarce and clarity matters.

A Rapid Follow-Up To Opus 5

The launch comes just two months after the debut of Opus 5 on July 24. Anthropic said Sonnet 5.5 and Haiku 5.5, the next models in the lineup, will follow “in the coming weeks,” with similar performance gains expected.

Safety Remains Central To The Release

Anthropic says Opus 5.5 is comparable to Mythos in biology and cybersecurity capabilities, which means the model is subject to the same safeguards as the company’s Fable model. Those restrictions limit the model’s use in areas such as discovering exploits in compiled programs or developing recognizable biological weapons, among other sensitive tasks.

The release is also notable because it is Anthropic’s first since CEO Dario Amodei publicly embraced calls to pace the frontier, a strategy designed to slow the rate of capability gains so alignment and safety measures can catch up. In a recent post, Amodei wrote: “I have become convinced that fully addressing the risks requires even more prudence, not just investing in risk prevention, but pacing the rate of capabilities advancement so that risk prevention has time to keep up.”

Preparing The Next Layer Of Oversight

Anthropic said Opus 5.5 underwent safety training broadly similar to earlier models, including alignment testing and pre-release evaluation by external groups such as METR and Frontier Design. At the same time, the company said it is already building more advanced training and evaluation systems for future releases, including stronger security and monitoring infrastructure.

“As AI becomes more capable, public policy should play a larger role in making sure the systems people rely on are safe,” the company wrote in its announcement. “That capacity takes time to build, and we’ve started to put the infrastructure in place to support it. We expect to share more details on these efforts soon.”
