The Centre for Development of Advanced Computing (C-DAC), Mohali, has developed the technology for aquaponic cultivation of plants, which is not only environment-friendly but also has high socio-economic benefits for the farming community.
Aquaponics is an emerging technique in which both fish as well as plants complement each other to sustain and grow. The fish waste provides organic food for plants and the plants naturally filter the water which is used to replenish the fish tank. There is no requirement for the use of soil and fertilisers.
“The process is completely organic, increases the productivity of the given land, saves water and also augments the farmers’ income,” Dr PK Khosla, director C-DAC, said, adding: “The technology has been developed and suitable protocols have been evolved for scientists and farmers,” he added.
A pilot project to develop the technology was awarded to C-DAC
Last year, Teracube released what it called a “sustainable smartphone” meant to combat e-waste with a long warranty and replaceable battery. If you didn’t get that one, you can now get its successor for about a tenth of the price of a new iPhone.
On Tuesday, Teracube announced the follow-up to its environmentally friendly phone that we reviewed earlier this year. It’s called the Teracube 2e and it brings along the promise of a four-year warranty and replaceable battery with slightly less RAM and storage than its predecessor for a noticeably leaner $200 price point.
And if you pre-order now, Teracube is offering an “early-bird special” price of $99 if you just can’t wait for the 2e.
The Teracube 2e is an Android 10 smartphone with 4GB of RAM, 64GB of storage, and a 1.8Ghz octa-core processor. Last year’s model had 6GB
Researchers from RMIT University have developed an eco-friendly zero-cement concrete, which all but eliminates corrosion.
Concrete corrosion and fatbergs plague sewage systems around the world, leading to costly and disruptive maintenance.
But now RMIT engineers have developed concrete that can withstand the corrosive acidic environment found in sewage pipes, while greatly reducing residual lime that leaches out, contributing to fatbergs.
Fatbergs are gross globs of congealed mass clogging sewers with fat, grease, oil and non-biodegradable junk like wet wipes and nappies, some growing to be 200 metres long and weighing tonnes.
These build-ups of fat, oil and grease in sewers and pipelines, as well as general corrosion over time, costs billions in repairs and replacement pipes.
The RMIT researchers, led by Dr Rajeev Roychand, created a concrete that eliminates free lime — a chemical compound that promotes corrosion and fatbergs.
XUZHOU, China, Sept. 28, 2020 /PRNewswire/ — Leading construction machinery manufacturer XCMG(SHE: 000425) has successfully applied cold in-place recycling technology with foamed asphalt (the “Technology”) on the maintenance project of G239 national highway section in Xinzhou, Shanxi Province.
XCMG spent six years tackling the fundamental problems in the application of sustainable, eco-friendly, highly-efficient technology in the area of pavement maintenance, with domestically made cold in-place recycling equipment, the XCMG XLZ2305K.
The model with significant power reserve, strong milling power combined with 2.3-meter-wide recycling width can reach a walking construction speed of 6-8 meters per minute to ensure stable, efficient construction.
Foamed asphalt requires a stringent asphalt-water ratio, and XLZ2305K’s asphalt and water flow control technology is the key. Three days after the completion of the Xinzhou construction, the coring test results of the recycled
