London Buses To Run On Coffee Fuel

Coffee: it’s every workaholic’s go-to beverage and, astoundingly, perfect for manufacturing sportswear. Nowadays, it isn’t just perfect for a pick-me-up — it’s potentially fueling London’s signature double-decker buses.

“Instead of sending a tonne of waste coffee grounds to landfill where it degrades and releases methane and CO2, we collect it, recycle it and turn it into a renewable fuel which is then used to replace further conventional fuels – so it’s a double saving”, [said] Bio-bean founder Arthur Kay.

Among the heaviest Americano consumers, Londoners contribute up to 200,000 tons of coffee waste annually. To make the most out of discarded grounds, Bio-bean is extracting 6,000 liters of oil to mix into fuel. The final blend is of 20% biofuel, which will also help to reduce carbon emissions.

“We’re not saying that it’s going to totally replace fossil fuels overnight,” Kay said.

“The amount of diesel produced globally is always going to be more than the amount of coffee.”

Considering London buses run nearly 2 billion trips a year, Bio-bean’s initiative could encourage alternative energy use. Perhaps a beer fuel may even be in talks.

Oxford Street To Become Full Pedestrian Zone

The streets of London have been getting some serious makeovers. Select popular boulevards are now energy-harvesting, which are not only high-tech, but also sustainable. To further counter traffic and lower carbon emissions, London mayor Sadiq Kahn is pedestrianizing shopping capital Oxford Street.

“Oxford Street is world famous with millions of visitors every year, and in just over a year the iconic part of the street west of Oxford Circus could be transformed into a traffic-free pedestrian boulevard.”

With over 500,000 visitors daily, Oxford Street is a breeding ground for potential vehicular accidents. (One every week, to be specific) Renovations will also allow easier access to the Elizabeth Line. The project will likely be rewarding — but at a cost of £60 million and years of remodeling.

The western section is due to finish by the end of 2018, with the eastern section between Oxford Circus and Tottenham Court Road going traffic free by December 2019. The final part, by Marble Arch, will then be turned over to pedestrians after 2020.

Without the hazard of passing vehicles, Oxford Street may be double the hot spot it is today.

Volkswagen To Debut Electric Zero-Emissions Beetle

Eco-friendly vehicles have come a long way from simply being prototypes. Manufacturers have been ambitious with emissions-free cars, even attempting to assemble them using resin. However, for big names in the industry, keeping it simple is key. Known for its funky appearance, the VW Beetle is getting another makeover — this time, it’s going electric.

“If we wanted to do a Beetle, electrically it would be much better than today’s model, much closer to history, because it could be rear-wheel drive,” said [VW chairman Herbert] Diess.

It may still be in the talks, but VW already has its hands full with an electric version of its classic microbus. Despite their overflowing to-do list, it seems fans of the Bug are on their toes. Thrilled prospective customers have been pleading with the chairman to follow through via letters and e-mails.

VW is aiming for a massive revamp of its vehicles by 2030. While that may seem a long ways away, its $24 billion budget speaks volumes about the group’s potential.

Sri Lanka To Wipe Gas Vehicles By 2025

When improper waste disposal procedures are producing islands of trash, it may be time to consider the weight of environmental issues. One by one, communities are diverting themselves from fossil fuels to pursue more environmentally friendly energy options. For state-owned vehicles in Sri Lanka, electric and hybrid cars will be stepping in as replacements as early as 2025.

Private owners have until 2040 to replace their cars, tuk-tuks and motorcycles, when the country plans to no longer allow any fossil fuel-burning vehicles on its roads… said [Finance Minister Mangala Samaraweera].

Home to roughly 6.8 million vehicles, Sri Lanka’s transition into electric will benefit the country immensely. To encourage a hassle-free switch, the government is encouraging consumers by cutting taxes on electric cars.

“The tax on electric cars will be reduced by over a million rupees (S$8,851) to encourage motorists to switch to clean energy,” Mr. Samaraweera told parliament.

On the other hand, Samaraweera is also hiking carbon and import taxes to discourage keeping gas vehicles. With inflation on the rise, Sri Lanka’s bumpy ride will hopefully segue into smoother (and sustainable) sailing.

eHighway Electrifies Trucks With Cables

With a rising number of electric buses and taxis headed for the streets, roads are having to undergo adjustments, too. Los Angeles is home to an excess of both trucks and smog. To revamp the deadly duo into something more eco-friendly, Siemens has installed its first electric highway where trucks can charge on-the-go.

“To have the road electrified and have these heavy trucks electrified is just far more efficient from the perspective that you don’t waste fuel, you save energy because the electric motor is far more efficient than the gas motor, and you have no emissions at all,” says Andreas Thon, the head of turnkey projects and electrification in North America.

The trucks are rigged onto overhead wires that run the entire length of the highway. The trucks themselves are cost-efficient, requiring significantly less maintenance than diesel motors. The highway also alleviates battery problems, as they don’t generate enough energy for heavy loads.

Thon says, “With this technology, you permanently feed energy into the truck.”

Siemens also hopes to install charging technology beneath road surfaces — but that will have to wait. After all, it does require a lot more science and a lot more money.

China Testing Trackless Autonomous Train

It’s been a year of firsts for the railway system — from going solar to launching its fastest model. Pushing its limits even further, China is test-driving its Autonomous Rail Rapid Transit system, which is fully electric and trackless.

ART bears the physical appearance of a train but it doesn’t rely on following a track. Instead, it follows a virtual route using an electric powertrain and tires. It’s expected to function much like an urban train or a tram, but since there’s no investment cost in laying down rails, it should be much cheaper to implement.

The train can only travel 15 kilometers at a time, but can fully recharge in just 10 minutes. Environmentalists will likely tip their hats off to the new system — it’s entirely emissions free! Smoggy China could surely use more sustainable public transport alternatives. Thankfully, its government has been taking other measures to ensure that its locals don’t further experience pollution-caused health issues.

40 percent of China’s factories have been shut down, and authorities are reportedly working on a timetable to end the sale of gas- and diesel-powered cars.

A round of applause for China — sounds fresh!

New Zealand To Test Humanitarian Emigre Visas

While environmental groups are tackling climate change on a grander scale, startups are handling smaller projects. Though it’s clear that innovations like Off Grid Box and SkyCool are making an impact, change can’t come quickly enough. To assist Pacific islanders displaced by natural disasters, New Zealand hopes to distribute refugee visas.

“There might be a new, an experimental humanitarian visa category for people from the Pacific who are displaced by rising seas stemming from climate change,” [said] James Shaw, New Zealand’s climate change minister… “and it is a piece of work that we intend to do in partnership with the Pacific Islands.”

The country is recovering from the repercussions of denying sanctuary to two deposed Tuvalu families. It seems the 1951 refuge convention, which defines a refugee as someone at risk of persecution, is making room for climate change as a legitimate oppressor.

“The lives and livelihoods of many of our Pacific neighbors are already being threatened and we need to start preparing for the inevitable influx of climate refugees,”

In the coming years, New Zealand will also up its refuge quota to 5,000 per annum. Looks like a storm of change has come.

Reforestation Project To Restore Brazilian Amazon

Saving cities up to $505 million a year, trees are the underdog we tend to dismiss too often. After planting a record-breaking 66 million trees in 12 hours, Indian volunteers have inspired even greater reforestation attempts. Conservation International is going big, attempting to restore 70,000 acres of the Amazon forest.

“If the world is to hit the 1.2°C or 2°C [degrees of warming] target that we all agreed to in Paris, then protecting tropical forests in particular has to be a big part of that,” [says] M. Sanjayan, CEO of Conservation International.

Stopping the seemingly trivial issue of deforestation can cut up to 37% of carbon emissions. To rehabilitate the Amazon, the group is using the muvuca strategy. This tactic combines over 200 native forest species that have a 90% chance of successful germination.

“With muvuca, the initial outcome is 2,500 species per hectare. And after 10 years, you can reach 5,000 trees per hectare. It’s much more diverse, much more dense, and less expensive than traditional techniques.”

Even better, Conservation International is employing indigenous communities and family farmers. A few million trees have already been planted, and it seems an appetite for change is growing along with them.

Cemented Plastic Makes Concrete Stronger

The existence of eco-friendly, weather-resistant structures such as Thailand’s bamboo building are evidence that designers are saving the planet. To drive a point, MIT students are embedding irradiated water bottles into cement to make concrete more robust and sustainable.

The research revealed that exposing the plastic to gamma radiation actually made it stronger. The irradiated plastic was then ground into a powder and mixed with cement. The subsequent concrete was up to 20 percent stronger than concrete made without the irradiated plastic.

Engineers found the added plastic (only 1.5% of the concoction) made concrete significantly denser. If you’re skeptical about incorporating the mix into future room renovations, don’t worry — it isn’t radioactive. Furthermore, using plastic will potentially relieve a few dozen landfills.

“Concrete produces about 4.5 percent of the world’s carbon dioxide emissions,” says [MIT professor Michael] Short. “Take out 1.5 percent of that, and you’re already talking about 0.0675 percent of the world’s carbon dioxide emissions. That’s a huge amount of greenhouse gases in one fell swoop.”

Environmentalists might campaign for a plastic-free society — but it isn’t the easiest option. Perhaps, now, it’s all about redirecting your waste to where it will be most useful.

Oxford To Ban Non-Electric Vehicles To Cut Emissions

The steady rise of electric vehicles will soon leave petrol and diesel cars in the dust. BMW is launching electric buses all over Europe, while the London Taxi Company is replacing old cabs. A few months later, the U.K. remains on top of the eco-ladder, with Oxford planning to eliminate non-electric vehicles.

The scheme aims to cut levels of nitrogen dioxide, the majority of which comes from traffic fumes, by three-quarters.

To give distributors leeway, Oxford will be imposing the ban in 2020, increasing the affected zone by 2035. We all know electric vehicles aren’t the most affordable, so locals may have to do some walking. The plan is projected to cost £7 million, but the city council deems the shift will be well worth it.

Oxford city councillor John Tanner said a “step change” is urgently needed as toxic air pollution is “damaging the health” of residents.

It’s a bold move, Oxford, but hopefully a successful one.
