A strong cup of coffee is one of life’s simple pleasures – and something that more people in the Emirates are enjoying.
Figures from the International Coffee Organisation show imports into the country more than doubled between 2008 and 2018.
This seems appropriate given that coffee drinking is traced back to the Arabian Peninsula and, specifically, to 15th century Yemen.
But our fondness for the caffeine-rich bean leaves vast amounts of spent coffee grounds. Of the more than 10 million tonnes generated globally each year, much ends up in landfill sites.
It is golden waste. It could be turned into value-added products and could create job opportunities
Scientists in the UAE and elsewhere are exploring other ways to use coffee beans, which are rich in energy – 20 per cent of their content is fats or oils – and contain useful chemicals.
Among those working in this area is Dr Eyas Mahmoud of the department of chemical and petroleum engineering at UAE University in Al Ain.
"Spent coffee grounds have been proven to be a potential feedstock to produce biodiesel, biogas, bioethanol, fuel pellets and bio-oil, besides their promising potential to produce bioactive compounds, adsorbents, compost and polymers," Dr Mahmoud and his co-authors wrote in a 2019 paper in the journal Fuel.
The researchers said processing the grounds offered environmental benefits, created jobs and produced many “value-added” products.
It is a complex picture, though, as shown by a 2020 study co-authored by Dr Vesna Najdanovic, a senior lecturer at Aston University in England, who found several environmental pluses and minuses linked to approaches such as composting, conversion into biodiesel, incineration and using landfill sites.
Dr Najdanovic streamlined the creation of biodiesel from waste coffee, which has typically been a two-stage process.
In the first step, they are mixed with the solvent, hexane, and the concoction heated so the oils are extracted before the solvent is evaporated off.
In the second stage, methanol (an alcohol) and a catalyst are added to produce biodiesel. The remaining solid can be burnt as fuel.
By determining the optimal concentrations and ratios of the substances, Dr Najdanovic created a quicker and cheaper one-step process that eliminated the need for the solvent.
“It decreases the investment needed if you can do everything in one pot,” she said.
Energy costs were also reduced, she said.
While research has been going on for many years and scientists and companies have developed numerous "proof of concept" initiatives showing such technology works – even using the biodiesel to power buses in London – major commercialisation appears to be lagging.
“To the best of my knowledge there’s no large commercial use,” said Dr Najdanovic. “From a scientific point of view, its technical feasibility is proven. It now needs to move to the next technology readiness by uptake by the industry.”
An extra push could come from making more use of some of the more than 1,000 chemicals present in waste grounds for the making of, for example, cosmetics or medicine.
Dr Gopalakrishnan Kumar, of the University of Stavanger in Norway, and his postgraduate researcher Georgeio Semaan are employing anaerobic digestion, where microorganisms process the material to produce biogas.
“We’ve been trying to find the parameters at which it would work best before upscaling – the right temperatures, solid-to-liquid ratio, acid concentration and processing times,” said Mr Semaan.
The method generates methane, a gas that can be burnt to produce electricity or to heat houses, for example, or used in further chemical processes to produce valuable substances.
The solid portion generated, which the researchers are characterising, may require additional processing, possibly involving microorganisms again, to produce, for example, enzymes useful in industry. Generating high-value chemicals is, they say, preferable to burning leftover solid as fuel.
“We’re trying to develop a biological process where we can produce both value-added products and fuel products so it can be cost effective,” said Dr Kumar, who has collaborated with Dr Mahmoud at UAE University.
“Rather than one product, what about three or four? That’s why we’re working with biological processes.”
Government support to companies or investment in research could move the industry further ahead and Mr Semaan, who was raised in Kuwait, hopes the technology sparks interest in the Gulf region.
“Gulf countries in the Middle East are more than willing to invest in new technologies if they see the benefit in it for them in the long term,” he said.
“The idea is to start implementing it and talk about it and raise awareness in these countries.”
Dr Kumar also thinks that over the next five to 10 years, as the technology develops, commercialisation could happen in earnest.
“It’s golden waste. It could be turned into value-added products and could create job opportunities,” he said.

No more lice
Defining head lice
Pediculus humanus capitis are tiny wingless insects that feed on blood from the human scalp. The adult head louse is up to 3mm long, has six legs, and is tan to greyish-white in colour. The female lives up to four weeks and, once mature, can lay up to 10 eggs per day. These tiny nits firmly attach to the base of the hair shaft, get incubated by body heat and hatch in eight days or so.
Identifying lice
Lice can be identified by itching or a tickling sensation of something moving within the hair. One can confirm that a person has lice by looking closely through the hair and scalp for nits, nymphs or lice. Head lice are most frequently located behind the ears and near the neckline.
Treating lice at home
Head lice must be treated as soon as they are spotted. Start by checking everyone in the family for them, then follow these steps. Remove and wash all clothing and bedding with hot water. Apply medicine according to the label instructions. If some live lice are still found eight to 12 hours after treatment, but are moving more slowly than before, do not re-treat. Comb dead and remaining live lice out of the hair using a fine-toothed comb.
After the initial treatment, check for, comb and remove nits and lice from hair every two to three days. Soak combs and brushes in hot water for 10 minutes.Vacuum the floor and furniture, particularly where the infested person sat or lay.

Tips for job-seekers
- Do not submit your application through the Easy Apply button on LinkedIn. Employers receive between 600 and 800 replies for each job advert on the platform. If you are the right fit for a job, connect to a relevant person in the company on LinkedIn and send them a direct message.
- Make sure you are an exact fit for the job advertised. If you are an HR manager with five years’ experience in retail and the job requires a similar candidate with five years’ experience in consumer, you should apply. But if you have no experience in HR, do not apply for the job.

What sanctions would be reimposed?
Under ‘snapback’, measures imposed on Iran by the UN Security Council in six resolutions would be restored, including:
- An arms embargo
- A ban on uranium enrichment and reprocessing
- A ban on launches and other activities with ballistic missiles capable of delivering nuclear weapons, as well as ballistic missile technology transfer and technical assistance
- A targeted global asset freeze and travel ban on Iranian individuals and entities
- Authorisation for countries to inspect Iran Air Cargo and Islamic Republic of Iran Shipping Lines cargoes for banned goods

When Umm Kulthum performed in Abu Dhabi
Known as The Lady of Arabic Song, Umm Kulthum performed in Abu Dhabi on November 28, 1971, as part of celebrations for the fifth anniversary of the accession of Sheikh Zayed bin Sultan Al Nahyan as Ruler of Abu Dhabi. A concert hall was constructed for the event on land that is now Al Nahyan Stadium, behind Al Wahda Mall. The audience were treated to many of Kulthum's most well-known songs as part of the sold-out show, including Aghadan Alqak and Enta Omri.
