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.
As one of the world’s most in-demand resources, paper has a massive carbon footprint. Because of the waste it creates, many are recycling or seeking paper alternatives. Startup MOO produces business cards made with fabric waste, while Paper Saver is a no-new-paper journal. Now, a Dutch province is recycling tons of toilet paper into a 1km bike path for cyclists.
The bicycle path uses what’s called tertiary cellulose, extracted from waste streams, says Erik Pijlman, director at KNN Cellulose, one of the partners on the project. “We take the cellulose out of these streams and once again make it into a [raw material],”
But not to worry — you won’t be seeing any remnants of used tissues on the bike path. The process includes sifting paper fibers, which are then cleaned, sterilized, bleached, and dried. To say the technique is doing fine is an understatement — it’s taking over Dutch roads.
“What we did is not only create technology and prove that it works, but we also have a market that is willing to take in the material,” Pijlman says. “And that’s really the next step in this kind of development.”
The fiber can also be used in creating filters, biofuel, and textiles, among other things. Of course, while in theory it’s useful in creating other products, we’ll keep it away from direct human contact. No one wants a stinky pillow case.
With an increasing number of industries stepping away from fossil fuels, eco-friendly substitutes are all the hype. Over time, both human and cow excrement have proved useful in the kitchen and as gas replacements. Unsurprisingly, an Israeli study has found turkey poop to be a valuable resource in producing combustible biomass fuel.
“Environmentally safe disposal of poultry excrement has become a significant problem,” said the researchers in a statement. “Converting poultry waste to solid fuel, a less resource-intensive, renewable energy source, is an environmentally superior alternative that also reduces reliance on fossil fuels.”
The process converts turkey stool into hydrochar and biochar. Both materials produce much less methane and ammonia as compared to traditional coal.
“This investigation helped in bridging the gap between hydrochar being considered as a potential energy source toward the development of an alternative renewable fuel,” [environmental hydrology and microbiology professor Amit] Gross said. “Our findings could help significantly reduce greenhouse gas emissions associated with electricity generation and agricultural wastes.”
At this stage in the game, researchers at the Zuckerberg Institute seem to have killed two birds with one stone. It looks like these turkeys are off the dinner menu.
When it comes to vehicles of the future, it seems the possibilities are limitless. Planes, in particular, have broken boundaries — running on electric or on no motor at all. Many advancements are still under wraps, or completely theoretical, save for Qantas’ latest shocking achievement. The airliner successfully piloted a trans-Pacific flight on 10% eco-fuel derived from mustard seeds.
The biofuel is reportedly capable of reducing carbon emissions by over 80 percent as compared to regular jet fuel. This means that the blended fuel used in… [the] flight should have resulted in a 7 percent reduction, which works out to 18,000 kg (39,683 lb) in reduced carbon emissions.
The Carinata mustard plant makes a perfect contender as the world’s leading aviation biofuel. Able to thrive under unsuitable conditions, the little-seed-that-could also improves soil quality and prevents erosion.
“Our work with Agrisoma will enable Australian farmers to start growing today for the country’s biofuel needs of the future,” says Qantas International CEO, Alison Webster.
Qantas’ ultimate goal is to maintain a near million acres of Carinata and produce 200 million liters of biofuel annually. If you’ve ever doubted the impact of agriculture, you may now consider switching gears.
We’ve all heard of recycled cosmetics packaging, but recycled cosmetics? That’s a different story. Especially if we’re talking fish guts — but this group of researchers think they could be useful. Jennifer Murphy of the Ocean Frontier Institute has recently manufactured nail polish from mussel shells.
“We presented at the Newfoundland Aquaculture Association and she was presenting all the different things like acid mine drainage treatment and road salt, and then she showed the nails. All the questions were about the nails.”
“It’s really sparkly, it’s very pretty,”
The fish waste is also used in products such as fuel, road salt, and animal feed. In fact, fish oil mixed with regular oil can produce enough power to run a small boat.
[Institute professor] Hawboldt said sustainability and smaller impacts on the earth are a natural byproduct of using fish waste to make more money from [fisheries].
The institute’s primary goal is to figure out which products work best from each species and region. As it seems, different breeds work towards different purposes. Perhaps it’s about time for a manicure?
