There’s lots of free advice and money-saving tips on how to start recycling more in your office in this article at (run by ValPak).

The website takes you through a set of simple slides with a handy checklist of ‘things to do’ to get started or to improve your current office recycling scheme.

We know all about that here at GreenTech, since our own inkjet and toner cartridge recycling scheme, where you can recycle printer cartridges and get paid up to £12, has been going strong for 10 years now.

Some of the advice from includes:

  • Nominate a waste recycling champion
  • Create an environmental group/committee

Hybrid vehicles and electric vehicles have been around for a while now but the concept of hydrogen-powered automobiles is a relatively new concept. We’ve yet to see a commercially viable hydrogen-powered vehicle.

However, Scottish and Southern Electricity (SSE) has agreed to test hydrogen-fuelled vans in an attempt to decarbonising its fleet of vans which regularly travel the length and breadth of the country. (more…)

Earlier in July, we saw a Swiss-built Solar Impulse completed the first ever 24-hour flight by a manned solar-powered aircraft, reaching a record-breaking height of 8,500m. Meanwhile, a month later UK engineering firm QinetiQ’s unmanned Zep hyr plane flew for 82 hours and 37 minutes above the US Army’s Yuma Proving Ground in Arizona.

Now, the aircraft manufacturing giant Boeing has confirmed that it is working on a space-age plane design that could keep flying for up to five years using only solar power. (more…)

Last week we told you about Yahoo’s chicken coop-inspired green data centre that uses 100 percent outside air for cooling. Well, Capgemini UK is boldly claiming to have created the most sustainable datacentre in the world in Swindon, where the climate is apparently optimal for the fresh-air cooling system it has implemented.

Scientists Develop Self-Repairing Solar Cells

Self-Healing Solar Cell

This proof-of-concept version of the photoelectrochemical cell, which was used for laboratory tests, contains a photoactive solution made up of a mix of self-assembling molecules (in a glass cylinder held in place by metal clamp) with two electrodes protruding from the top, one made of platinum (the bare wire) and the other of silver (in a glass tube). / Image Source: MIT

Modern solar materials, which range from the rigid-silicon panels found on rooftops to the flexible, organic type that can be coated like paint onto surfaces, all degrade over time when exposed to sun and oxygen. The result of this damage is that the material’s ability to turn sunlight into electricity decreases over time. (more…)

Last month we told you about a car that uses methane gas generated from the sewage-treatment process. Well, here’s another interesting project from an American conceptual artist Matthew Mazzotta who would like to see the dog poop fed into digesters that use it to produce methane gas, which is then used for fuel. The project/installation — called Park Spark at a dog park in Cambridge, Massachusetts — features a lamp that lights the park at night, powered by nothing but dog doo. (more…)

Recycling companies are coming up with innovative ways to pay the people for recycling their empties. In one such initiative, a Reverse Vending Machine (RVM) — that takes in empty recyclable bottles and cans, and gives out cash in return — have been introduced at the Centro Hollywood shopping mall in Adelaide, Australia.

How Does It Work?

The empties recycling process starts with users placing their empties in the RVM’s feed unit. Each bottle or (more…)

Yahoo’s Chicken Coop-Inspired Green Data Centre Uses 100pc Outside Air for Cooling

Large Data Centres have traditionally been using large power-hungry chillers for air conditioning and are a cause of concern for the Green companies. Yahoo has taken an initiative towards reducing the energy cost of these large data centres by launching the first chicken coop-inspired data centre, which utilise outside air and can reduce cooling power and costs, in Lockport, New York.

The 155,000-square-foot data centre, which can accommodate 50,000 servers, is cooled almost 100 percent by outside air and uses 40 percent less energy than typical data centres. Yahoo’s Coop design attributes just 1 percent of its annual energy consumption to cooling. (more…)

Recycling Bins ‘Snitch’ On Citizens Who Don’t Recycle

Some of us don’t recycle the recyclable items often enough and show lethargic attitude when it comes to taking out the recycling bins and send the recyclable items to the recycler. Well, citizens of Cleveland, Ohio, will have to face $100 (£64.85) fine if they do this anymore with, so called, ‘smart’ recycling bins.

The Cleveland city government is aiming to launch a large number of “smart” recycling bins equipped with radio frequency identification (RFID) chips and bar codes which will keep track of how often residents take them to the curb starting from next year. (more…)
