Prof Stephen Wallace from the University of Edinburgh is among those turning the fatbergs into perfumes. "It's a crazy idea," he admits to me, "but it works."
Fatbergs are accumulated lumps of fat from cooking oils, toilet and other food waste that people put down their drains. Prof Wallace gets his from a company that specialises in fishing them out of sewers and turning them into biofuels. They arrive at the lab in a tube.
The first step is to sterilise the material in a steamer. Prof Wallace then adds the specially modified bacteria to the remnants of the fatberg. The bacteria have a short section of DNA inserted, to give the bacteria their particular properties.
The fatberg gradually disappears, as the bacteria eat it, producing the chemical with the pine-like smell - this can be used as an ingredient in perfumes.
Her Highness Sheikha Mahra Bint Mohammed Bin Rashid Al Maktoum recently divorced her husband. Inspired by this event (or to celebrate it?), she's launching a new perfume called "Divorce".
Not exactly a perfume to give a romantic attachment. I guess she's aiming at a very specific market niche.
The Air Company is developing technology to make aviation fuel directly from CO2. As a side gimmick, they also used their technology to make ethanol from CO2, which they then used as a base for a perfume. They claimed it was "the world’s first carbon-negative fragrance."
I wonder what makes it carbon negative, as opposed to carbon neutral?
From what I understand, ethanol made from plants would be carbon neutral if it weren't for the energy used to process the plants into fuel. Because plants take in carbon as they grow, and this carbon is then released again when the fuel is burned.
The Air Company specifies that they used only wind and solar energy to make the ethanol. But even so, once someone uses the fragrance, the carbon will be released into the atmosphere again. Doesn't that make it carbon neutral, rather than negative?
Introducing Knead: Eau De Pretzel. A perfume with the warm, buttery and slightly sweet scent of hot and handmade pretzels. This tantalizing scent should come with a warning that you will smell good enough to eat.
"Abduction is a unisex eau de parfum inspired by scents described by close encounter experiencers – the product of a collaboration between Joe Merrell and perfumer Christopher Gordon."
On first blast, there is some sweet spice that could be cinnamon or clove, and then the main body of the fragrance enters, which is a very well done "damp" accord that smells like wet concrete or cardboard. It's a scent that you swear you've smelled somewhere before but can't quite place it. It's not quite a pleasant smell, which is what makes the fragrance a little eerie and disquieting. There is a bit of sour metals mixed in, which we can take to be the smell of the interior of the alien ship, and the ozonic notes make the scent light and transparent.
A fragrance recently released by Thomson & Craighead is described as "a complex fragrance based on olfactory materials detailed in The Book of Revelation as it appears in the King James Bible first published in 1611."
Some of those materials:
Thunder, blood, hail and fire, the creatures of the sea that have died, wormwood, a rod of iron, the opened earth, a grievous sore, the blood of a dead man, every living soul [who has] died in the sea, plagues, wine of her fornication, animal horns, filthiness of her fornication, blood of the martyrs of Jesus, flesh burned with fire, [and] a lake which burneth with fire and brimstone.
