Ian Falconer kept thinking about the heaps of discarded plastic fishing nets he saw at Newlyn harbor near his home in Cornwall, southern England.
“I thought ‘it’s such a waste,’” he said. “There has to be a better solution than it all going into landfill.”
Falconer, 52, who studied environmental and mining geology at university, came up with a plan: shredding and cleaning the worn-out nets, melting the plastic down and converting it into filament to be used in 3D printing. He then built a “micro-factory” so that the filament could be made into useful stuff.

“Every year, up to 1 million tonnes of fishing nets are discarded,” he said. “Most of that ends up in landfill or is burned, or worse still, finds its way back into the oceans. This showed there was another way for some of that material.”
The first big challenge he encountered when he started in 2016 was getting hold of the nets, but he badgered the Newlyn harbor master into giving him a few to test his theory in his kitchen.
Since its launch the following year, Falconer’s company OrCA (previously Fishy Filaments) has raised more than ￡1 million (US$1.34 million) from small investors in more than 40 countries. The investment funded the development of patented new machinery that can convert more than 20kg of nylon fishing nets an hour. He said the recycling process has less than 3 percent of the carbon impact of producing new nylon.
“When they get to us, this particular type of fishing nets have typically been used by Cornish fishers for around six months,” he said. “They are routinely swapped out because their surfaces become cloudy due to wear and the buildup of an algal biofilm. With time and repeated use, eventually the fish can sense them in the water and avoid them.”
“Skippers can see their catches fall as their nets age, and it makes sense to replace them,” he added.
The nets that go into the shredder come out as small blue-green beads that Falconer sells to 3D printing companies, which convert them into strings of filament used in 3D printing. They are also sold around the world to replace new plastic in more conventional products that are made using injection molding.
Falconer’s shipping container office is full of items made from the raw material: sunglasses, light shades, bottle openers, razor blade handles. It can be used for just about anything. The items he is most proud of are those made from his nylon mixed with waste carbon fiber — mostly from offcuts of car and airplane manufacturing. This stronger and more expensive product is used to make parts for racing bikes and super-light sunglasses, and industrial components such as electronic enclosures.
The carbon and nylon mix sells for up to ￡35,000 a tonne — more than the ￡12,000 a tonne pure nylon beads.
“Our process turns a liability of about ￡500 a tonne to pay to get someone to take the nets away, not to mention the environmental cost of that, into something of real value,” Falconer said. “Now, when I pass the piles of fishing nets on the harborside, I see piles of money.”
Falconer’s roster of clients, which includes Philips lighting, L’Oreal, Ford and Mercedes-Benz, is increasing as more companies see OrCA’s potential to help them reduce their carbon footprint by increasing the proportion of their products made from recycled materials.
Waste fishing nets are a problem in Cornwall, but are a much bigger problem in countries without established waste systems
“The EU wants automakers to use at least 20 percent recycled plastic by 2035,” he said. “Using ours is one of the easiest ways to do it.”
Falconer could make a good living continuing to recycle Newlyn fishers’ nets, but he has wider ambitions.
“Waste fishing nets are a problem here in Cornwall, but the same type of nets are a much bigger problem in other countries, especially those without established waste systems,” he said.
About 150,000 tonnes of nylon monofilament fishing nets are made every year, and, based on external reports, Falconer estimates production would soon rise to 200,000 tonnes.
The world’s total traditional nylon recycling capacity is less than 150,000 tonnes a year, so less than half the capacity that European carmakers need to meet their targets, and almost all of that is taken up with recycling carpets and other textiles.
To try to combat the problem, Falconer plans on exporting his recycling solution to any harbor that wants it. A container with all the equipment needed to run a small recycling plant would cost about US$500,000 if built in the UK.
Falconer said he has already received inquiries from 14 countries, including Brazil, Colombia, Ghana, South Africa and Vietnam.
“The beauty of it is that it all fits in a shipping container and pretty much anyone can operate it,” he said. “So you could have one of these at every harbor around the world, converting a costly and hazardous waste into a profitable raw material.”
PERSISTENT RUMORS: Nvidia’s CEO said the firm is not in talks to sell AI chips to China, but he would welcome a change in US policy barring the activity Nvidia Corp CEO Jensen Huang (黃仁勳) said his company is not in discussions to sell its Blackwell artificial intelligence (AI) chips to Chinese firms, waving off speculation it is trying to engineer a return to the world’s largest semiconductor market. Huang, who arrived in Taiwan yesterday ahead of meetings with longtime partner Taiwan Semiconductor Manufacturing Co (TSMC, 台積電), took the opportunity to clarify recent comments about the US-China AI race. The Nvidia head caused a stir in an interview this week with the Financial Times, in which he was quoted as saying “China will win” the AI race. Huang yesterday said
Nissan Motor Co has agreed to sell its global headquarters in Yokohama for ￥97 billion (US$630 million) to a group sponsored by Taiwanese autoparts maker Minth Group (敏實集團), as the struggling automaker seeks to shore up its financial position. The acquisition is led by a special purchase company managed by KJR Management Ltd, a Japanese real-estate unit of private equity giant KKR & Co, people familiar with the matter said. KJR said it would act as asset manager together with Mizuho Real Estate Management Co. Nissan is undergoing a broad cost-cutting campaign by eliminating jobs and shuttering plants as it grapples
TEMPORARY TRUCE: China has made concessions to ease rare earth trade controls, among others, while Washington holds fire on a 100% tariff on all Chinese goods China is effectively suspending implementation of additional export controls on rare earth metals and terminating investigations targeting US companies in the semiconductor supply chain, the White House announced. The White House on Saturday issued a fact sheet outlining some details of the trade pact agreed to earlier in the week by US President Donald Trump and Chinese President Xi Jinping (習近平) that aimed to ease tensions between the world’s two largest economies. Under the deal, China is to issue general licenses valid for exports of rare earths, gallium, germanium, antimony and graphite “for the benefit of US end users and their suppliers
Dutch chipmaker Nexperia BV’s China unit yesterday said that it had established sufficient inventories of finished goods and works-in-progress, and that its supply chain remained secure and stable after its parent halted wafer supplies. The Dutch company suspended supplies of wafers to its Chinese assembly plant a week ago, calling it “a direct consequence of the local management’s recent failure to comply with the agreed contractual payment terms,” Reuters reported on Friday last week. Its China unit called Nexperia’s suspension “unilateral” and “extremely irresponsible,” adding that the Dutch parent’s claim about contractual payment was “misleading and highly deceptive,” according to a statement
