A New York couple built their 2,500-sq-ft home for $40,000 using YouTube and discarded materials; after selling it for $290,000, they moved to Florida with no jobs and became scuba instructors

A New York couple built a 2,500-square-foot home for just $40,000 using online tutorials and materials collected from local dumps. They later sold it for $290,000 and used the money to make a sudden move to Florida without jobs or permanent housing arranged. Jessica Patrzyk, 34, and her husband left their life in rural Worth, … Read more

Taiwanese students are turning discarded oyster shells and coral waste into 3D-printed structures for damaged reefs

A group of students in Taiwan has found a way to give discarded shellfish waste a second life beneath the waves. Their project, named Reefvive, takes oyster shells and coral gravel that would otherwise be thrown away and turns them into 3D-printed bases for growing coral. According to the James Dyson Award, the structures have … Read more

MIT scientists developed a way to turn discarded plastic into strong building materials, with recycled composites already used in a 40-foot bridge

MIT scientists developed a way to turn discarded plastic into strong building materials, with recycled composites already used in a 40-foot bridge

A new MIT-backed company is turning discarded plastic into structural parts for buildings and infrastructure. Atlas Building Composites has developed an AI-powered robotic manufacturing platform that shreds single-use plastic, melts it, and fuses it with American-made fiberglass. The resulting composite is then formed into parts such as foundations, decks, and trusses using large-scale 3D printing. … Read more

In 2024, New York turned 250 discarded Christmas trees into nearly 600 feet of breakwaters; by fall, the trees were trapping sediment around a restored salt marsh

In 2024, New York turned 250 discarded Christmas trees into nearly 600 feet of breakwaters; by fall, the trees were trapping sediment around a restored salt marsh

What looked like holiday waste ended up helping rebuild a fragile salt marsh at Jamaica Bay, where the trees were turned into nearly 600 feet of natural breakwaters. In 2024, 250 discarded Christmas trees were repurposed into nearly 600 linear feet of natural breakwaters at New York’s Jamaica Bay Wildlife Refuge, helping protect newly planted … Read more

Australian researchers buried discarded plastic pipes inside mine waste-rock piles; cameras showed northern quolls entering and leaving the artificial dens, with conditions similar to natural shelters

Australian researchers buried discarded plastic pipes inside mine waste-rock piles; cameras showed northern quolls entering and leaving the artificial dens, with conditions similar to natural shelters

The researchers looked at whether high-density polyethylene (HDPE) pipes could be used in waste-rock piles to create inexpensive artificial dens. What appears to be industrial waste could provide a small refuge for one of Australia’s most threatened marsupials. Researchers have begun converting discarded plastic piping into artificial dens at former mining sites in north-western Australia … Read more

In 1997, Texas mixed discarded roofing shingles into two 1,000-foot Highway 31 test sections; years later, officials said their performance was comparable to conventional asphalt

In 1997, Texas mixed discarded roofing shingles into two 1,000-foot Highway 31 test sections; years later, officials said their performance was comparable to conventional asphalt

Highway engineers in Texas have shown that discarded household roofing shingles can be recycled into durable road surfaces that perform as well as standard asphalt after years of heavy traffic. In 1997, the Texas Department of Transportation (TxDOT) built two 1,000-foot test sections along State Highway 31 in the Dallas District using hot mix asphalt … Read more

In 2013, a UK beach began planting discarded Christmas trees to trap blowing sand; by 2026, the project had created 90 metres of new dunes that help defend homes from flooding

More than 2,000 Christmas trees were planted at St Annes beach in February 2026. (Photo: .visitstannes.info) Discarded Christmas trees are being used to help protect homes and businesses along the Fylde Coast in Lancashire, UK. Since the project began in 2013, old Christmas trees have been placed on St Annes beach to trap wind-blown sand … Read more

A Mexican entrepreneur turned discarded plastic into low-cost homes for families in poverty; each 430-460 sq ft house used 2 tonnes of waste, took 7 days to build and cost families about $280

An EcoDom prototype house built using its plastic panels. Plastic production has increased exponentially over the last few decades. A 2017 study published in Science Advances estimated that 8.3 billion tons of plastic have been produced globally since large-scale production began. Only a tiny fraction has been recycled, with huge amounts accumulating in landfills, ecosystems … Read more

In 2021, Alabama students began placing discarded Christmas trees along Gulf Coast dunes to trap sand; each year about 200 students now add roughly 3,000 native plants around them

By 2060, discarded solar panels could total 297 to 402 million tonnes worldwide; recycling them could generate almost $1 trillion in economic benefits

Solar Panel Waste: The Unknown Side of Solar Power Discarded solar panels could become a major global waste problem, with as much as 402 million tonnes of photovoltaic (PV) waste expected by 2060. But if these panels are recycled properly, the materials inside them could create almost $1 trillion (£770 billion) in economic value.According to … Read more
