Keeping a data centre cool on Earth is a surprisingly large part of the job. Cooling can swallow anywhere from a tenth to a third of a facility s entire energy budget, and the thirstiest sites drink millions of litres of water to do it. Move that data centre into orbit and the whole approach collapses. There is no air to blow across the servers, no cooling towers, and no river to dump the heat into. The only way left to get rid of waste heat is to radiate it away as infrared light into the blackness of space, through vast panels. That single fact shapes everything about the idea of computing in orbit.
Every computer turns electricity into heat, and a data centre is thousands of them packed together. Left unchecked, that heat would quickly cook the machines, so a large share of the effort and expense goes not into computing but into carrying the heat away.
The bill is real. Cooling commonly accounts for something in the range of a tenth to a third of a data centre s total energy use, and often more in hot climates. Much of that cooling relies on water, evaporated to carry heat off just as sweat cools skin. A single one-megawatt facility can get through tens of millions of litres a year, and the largest operators consume water by the billions of litres, a growing source of tension where supplies are tight.
On the ground, heat has easy ways to escape. It moves by conduction into cooler materials, by convection as air or water flows past and carries it off, and by evaporation in cooling towers. Every one of those methods depends on having a surrounding fluid, air or water, to hand the heat to.
Space has neither. The vacuum around a spacecraft is not cold air; it is very nearly nothing at all. With no air to convect into and no water to evaporate, and nothing to conduct heat into, the familiar cooling methods simply stop functioning. You cannot fan away heat that has nowhere to go.
There is one mechanism that still works in a vacuum, and only one: thermal radiation….
Environmental organisations yesterday urged the government to scrap the proposed Tk 5,745-crore North Dhaka 42.5-megawatt waste-to-energy (WtE) project in Aminbazar, alleging that it would impose a heavy financial burden, worsen air pollution, and undermine sustainable waste management.
They described the project as one of the country’s most expensive and environmentally damaging power initiatives.
Coastal Livelihood and Environmental Action Network (CLEAN), the Bangladesh Working Group on Ecology and Development (BWGED) and the Bangladesh Environmental Lawyers Association (BELA) shared the findings at a press conference at a Dhaka restaurant.
In the keynote paper, Hasan Mehedi, chief executive of CLEAN, said at 85 percent of its capacity, the plant would generate around 316.5 million kilowatt-hours of electricity annually, at the purchase rate of Tk 26.79 per unit.
“If the plant utilisation declines, the tariff could rise to between Tk 47-75 per unit,” he added.
Also, the project agreement requires DNCC to supply 3,000 tonnes of municipal waste daily. If DNCC fails to deliver the agreed amount, it would have to pay US$50 per tonne of waste shortfall.
The speakers argued that as DNCC currently generates around 2,750 tonnes of waste daily, the arrangement could create financial incentives to generate more waste instead of promoting recycling and waste reduction.
They also expressed concern over environmental and health impacts, claiming the plant would emit about 4,11,392 tonnes of carbon dioxide annually, alongside ash, ultrafine particulates and toxic pollutants, including heavy metals, dioxins and furans, which pose serious health risks.
The keynote paper added that the same investment could install around 425MW of solar power capable of generating nearly 688 million units of electricity annually without fuel costs or harmful emissions.

Waste-to-Energy: Scrap Aminbazar plant project
As fruits traders in Lagos State count their losses due to spoilage of their items, a project that turns fruit waste into energy which powers streetlights and a few shops in Babajide Sanwo-Olu Market, Ketu, is helping traders to maintain a cleaner and safer environment, SULIYAT TELLA reports.

According to new research, rather than food processing leftovers ending up in landfills or compost, they could find a second life as a natural source of vitamin C, potentially replacing the synthetic form commonly used in supplements.
According to a report from Swansea Bay News, researchers from Swansea University and the nutrition startup BIOVIT are exploring the idea that nutrients stripped away during food processing could be recovered rather than discarded.
The outlet reports that Innovate UK is backing the effort, which centers on agricultural leftovers and food-processing byproducts. BIOVIT says preliminary findings suggest fruit and vegetable material can lose up to 60% of its vitamins and minerals during processing.
This lost material could be useful again if researchers can nail down a method for capturing and repurposing it.
In turn, researchers at Swansea University s Natural Products BioHUB are aiming to transform discarded food-processing material into a more sustainable, naturally sourced replacement for synthetic vitamin C.
Dr Farooq Shah, director of BioHUB, told Swansea Bay News that transforming the waste into useful supplements can help support circular manufacturing and strengthen local food supply chains.
Food waste is costly, resource-intensive, and environmentally damaging — and not every form of it can simply be donated or consumed.
In many cases, food processing leftovers must be handled carefully to ensure they are safe for human consumption. If nutrients can be safely extracted from those materials, it would provide another way to keep valuable resources in circulation rather than throwing them away.
A successful process could also affect the products people use every day. Vitamin C is widely used in supplements and fortified foods, and much of it is made synthetically. A recovered, natural version could give manufacturers another option while making better use of materials that would otherwise be discarded.

Fresh produce is highly perishable, but proper washing and storage can help make it last longer, saving money and reducing waste.
Quad Whitson, extension culinary nutrition and food safety program associate for the University of Arkansas Division of Agriculture, said that according to the U.S. Food and Drug Administration, about 30 to 40 percent of the food supply in the United States is wasted each year.
“Taking simple steps to store produce correctly can help families reduce waste, stretch their grocery budget, and keep food safe and of better quality for longer,” Whitson said.
Sarah Bakker, extension local food program lead for the Division of Agriculture, said proper storage also leads to better tasting produce.
“It keeps fruits and vegetables tasting better,” Bakker said. “Nobody wants slimy greens, moldy berries or rubbery carrots two days after buying them.”
Bakker said fresh produce should be washed before it is eaten, cut, peeled or cooked.
“The best practice is usually to wash produce right before use rather than before storing it, since extra moisture can make many items spoil faster,” Bakker said. “To wash produce safely, rinse it under clean, cool running water and gently rub with your hands.
“For firmer produce, such as melons, cucumbers, carrots or potatoes, a clean produce brush can help remove visible dirt or debris,” she said.
Washing produce with inedible outer peels or rinds is still important, Bakker said, because a knife can transfer contamination from the outside to the inside when cutting.
“Leafy greens may be an exception and can be washed before storage as needed, but they should be dried very well before going into the refrigerator,” Bakker said. “Greens labeled as ‘pre-washed,’ ‘triple-washed’ or ‘ready-to-eat’ do not need to be washed again.”
