Researchers Invent Way to Turn Harmful Mine Waste into Healthy Soil

in Enviroment 203 views

An Australian-Canadian science and engineering team has discovered a way of turning mine waste into arable soil that is already being used to grow maize and sorghum.

‘Tailings’ is the official industry term for mineral waste leftover after separating away all the useful metals from mined material. Typically toxic from heavy metals and unusable for anything else because of this, tailings are kept in storage facilities to prevent them from polluting groundwater or farmland.

Hoping to save billions of dollars in such storage fees and remove the threat of disasters that occur when such facilities break down or are abandoned, a team from the universities of Queensland and Saskatchewan sought to see whether it was possible to convert this lifeless rock into healthy soil by returning microbial life to it.

“Tailings have no biologically friendly properties for growing plants. Roots and water cannot penetrate them, and soluble salts and metals in tailings can kill plants and soil microbes,” said Longbin Huang a professor at the Univ. of Queensland. “If you wait for nature to slowly weather the tailings and turn them into soil, it could take a couple thousand years.”

Using the Canadian Light Source (CLS), Huang and his team found a way to accelerate this process of repopulating the tailings with soil microbes.

The CLS is a giant synchrotron, a type of circular particle accelerator. It works by accelerating charged particles (electrons) through sequences of magnets until they reach almost the speed of light.

Using the CLS’s synchrotron light the scientists could visualize the detailed mechanism of how they were able to develop the organic-mineral interfaces and revitalize the tailings.

“We needed to use the SM beamline to unravel at the nanometer scale the immediate interfaces and how the minerals change, and how they interact with organics,” said Huang. “The facility access and the expert inputs of the beamline staff were critical to enable us to collect quality data and therefore to have reliable scientific evidence.”

Farmers Show off Mammoth Produce at County Fair Headlined by 1,300 lbs. Pumpkin

in Food 313 views

At last weekend’s Malvern Autumn Festival in the UK, growers from across the Isles showed off the truly frightening proportions that vegetables can grow to, headlined by massive pumpkins brought in on a forklift.

4th place winner Tim Saint transported his whopping 667 lbs. pumpkin in a trailer to display at the event held over the weekend in England’s Worcestershire.

Even though he needed a pallet, trailer, and industrial strapping to move the thing, his was a small fry compared to Curtis Leach’s 1st prize-winning pumpkin that arrived at weights usually reserved for cars.

At 638 kilograms, or 1,373 lbs, the gargantuan gourd was 40 kilograms more than the second-place entry, but half as heavy as the current Guinness World Record for heaviest pumpkin, which was 2,700 pounds.

“I grew a 667 lbs. pumpkin this year which I’m delighted at,” said Mr. Saint. “I’ve been growing pumpkins for 20 years and that’s the biggest I’ve ever done It’s got to be over 3ft tall at least, I’m 6ft tall myself and it’s big.”

“The secret is just plenty of water and manure, plenty of cow manure especially,” added Mr. Saint, who did take 1st prize for largest beetroot. “It takes a lot of water, I normally give it five watering cans of water a day.”

Vacant Office Near D.C. Turns Into Indoor Farm–Using Empty Buildings to Grow Food

in Food 208 views

Arlington, Virginia is like a gateway to the city of Washington D.C. Part of the Metro line, but across the Potomac, it’s nevertheless a busy area and not the kind of place you’d expect to be able to get minutes-old, farm-fresh produce.

But Area 2 Farms is growing greens, herbs, and root vegetables in a vertical farm thanks to the dearth of traditional office tenants. With high-rise office space remaining vacant even after the end of the pandemic, landlords are open to ideas.

Jackie Potter and Tyler Baras pitched the idea of an indoor farm and it was obviously a good one because Area 2 is already well-established in the Arlington area such that they offer subscription delivery of fresh veggies to fellow urbanites starting at $40 per week.

North country farmers markets preparing for fruitful season

in Enviroment 290 views

CANTON — Summer is awakening farmers markets across the north country from their winter hibernation. Here’s what to know about this year’s farmers markets in Jefferson, St. Lawrence and Lewis counties.

Some markets in St. Lawrence County have already begun.

The Potsdam market began last week, and is held from 9 a.m. to 2 p.m. Saturdays in Ives Park.

Ogdensburg’s market takes place from 11 a.m. to 4 p.m. Thursdays at 2321 Ford St. Extension.

According to GardenShare’s local food guide, the Ogdensburg market may operate other days, but updates can be found on its Facebook page.

Massena’s market starts in July, and takes place from 10 a.m. to 2 p.m. Sundays at 105 Harte Haven Plaza.

Hammond’s market starts June 15, and will be from 3 to 6 p.m. Wednesdays.

Gouverneur’s farmers market starts June 3, and will be from 9 a.m. to 2 p.m. Thursdays at the village park on Main Street.

Canton’s market starts May 27, and is from 9 a.m. to 2 p.m. every Tuesday and Friday at the village park.

The Akwesasne market starts June 18, and is from 11 a.m. to 2 p.m. Wednesdays and Saturdays at 580 Route 37, Hogansburg.

Most of the markets accept Supplemental Nutrition Assistance Program EBT, Double Up Food Bucks, and Farmers Market Nutrition Program checks. Some small changes are coming to the Potsdam, Canton and Gouverneur markets, according to Carlene L. Doane, executive director of GardenShare.

“GardenShare is taking on a shared market management for those markets,” she said. “So instead of each one having its own manager, it will be one person managing all three.”

Ms. Doane said this will help streamline the market for vendors and customers who might have questions or concerns, and therefore don’t need to wonder who to approach.

“If a customer has concerns, it’s going through one person now instead of three,” she said.

Ms. Doane encouraged people to attend their local farmers market.

Hundreds of US Cities Composting Their Food Waste Helps Farmers and Cuts Tons of Emissions

in Enviroment/Food 724 views

Last week, new water restrictions issued for millions of residents of Southern California highlighted the need to make agriculture more efficient—and a new statewide composting mandate is providing the solution.

California leads the nation in food production, which requires a lot of water, and now because they became the second state in the nation after Vermont to make large-scale composting required by law means we can have our produce ‘cake’ and eat it, too.

Compost Awareness Week, which begins today, may sound superficial, but we need to know that farms can grow up to 40 percent more food in times of drought when they use compost—and when citizens dump their coffee grounds and banana peels into a bin for pick up, they are feeding the soil, while guarding against water shortages.

City composting programs produce thousands of truckloads of finished compost that go onto farms, orchards, and vineyards, creating a natural sponge that attracts and retains moisture. Not only that, the recycling loop is combatting global warming.

Food waste makes up nearly 20% of the stuff in our landfills. When that food decomposes, it releases methane; tens of times more potent than carbon dioxide, it’s one of the main greenhouse gasses fueling the climate crisis, and landfills are the third-largest source of methane emissions in the U.S.

More than 200 cities across the country, and many universities, have followed San Francisco’s lead and implemented curbside collection of food scraps for composting. In compliance with the new law—(SB 1383) requiring California cities to reduce landfilling of compostable materials by 75 percent by 2025—cities up and down California are establishing curbside programs that provide bins for food scraps, sticks, and leaves, so they can be turned into ‘black gold’ compost for farmers.

San Francisco-based Recology, an employee-owned company with a workforce of 3,800 operates 8 composting facilities in California, Oregon, and Washington serving nearly 150 communities. In 2020 alone, they recycled over 810,000 metric tons of organic waste, including food scraps and yard trimmings.

“This program gives individuals, communities and entire municipalities a way to do something very useful to help slow climate change—and to help get carbon out of the atmosphere and back into the soil where it belongs,” said Recology’s Robert Reed.

San Francisco’s pioneering food scrap collection program, which was maligned as something that would never work, created momentum for the statewide program.

“We started collecting food scraps separately from other trash in 1996,” Reed told GNN. “At the time, executives at the largest garbage companies were quoted in the trade press saying the San Francisco program had never been tried and would not work. They said our trucks would leak and our new program would fail.”

“In fact, our program worked and continues to work extremely well. San Franciscans have embraced curbside composting of food scraps together with sticks and leaves more than any other city in the country.”

Leaving No Molecule Behind: ‘Landfill of the Future’ Turns Farming Waste Into Soaps, Compost, and Candles

in Enviroment 259 views

Among sparsely populated communities in Newfoundland, a landfill for the future—where every molecule is accounted for and reused—is steadily growing its portfolio of circularly produced goods that utilize waste from the island’s forests, farms, and fisheries.

For clients, it’s just like any other landfill. They can go and dump whatever amount of biological waste that they have from their operations, and then drive off without ever needing to think about it again.

But for investors, for consumers, and for the world, 3F Waste Recovery is anything but ordinary.

“3F is founded on the principle that every molecule that comes through our door, we want to have an application for it,” Founder Ben Wiper explains to Hakai Magazine. “My vision is the landfill of the future—where producers can take anything they haven’t processed, to break it down into a form that has a function.”

Science has moved us into an increasingly molecularized world. It’s common to hear businesses accounting for things like protein or CO2, as if they’re counting assets, expenditures, or cash flow.

When a company has the technology to turn practically all kinds of biological waste into valuable consumer products, this accounting method becomes even more extreme. Every unit of lignin not burnt from a tree means one more unit of lignin needed from a tree that hasn’t been felled. Every unit of cod skin placed in a landfill is one more unit of cod skin needed from a living cod.
