Everyday household rubbish is being saved from landfill and turned into fuel to help power cement factories in the UAE.

Throwaway items such as plastic, paper and food scraps are being collected from households across Ajman and Umm Al Quwain to produce refuse-derived fuel (RDF) - a combustible fuel made of various types of waste.

For every 1,000 tonnes of items collected daily from homes in both emirates, about 80 per cent will be converted into alternative energy at the Emirates RDF plant in Umm Al Quwain.

The waste is sorted and turned into shredded combustible pieces - or fluff - before being dispatched to the factories.

Using this as an alternative energy source has an overall benefit on fuel costs, not to mention the environmental benefits

During a tour of the new waste-to-fuel site on Sunday, the plant's Dutch manager, Nicolaas de Koning, said the aim is to help cement factories reduce their CO2 production by generating up to 200,000 tonnes of RDF a year.

"It will be used in cement factories as a fuel and will partially replace the traditional use of gas or coal," he said.

“Eight hundred tonnes of RDF will replace approximately 500 tonnes of coal, which has an alarmingly high carbon footprint.

“Using this as an alternative energy source has an overall benefit on fuel costs, not to mention the environmental benefits.”

The large-scale plant, which should be fully operational later this month and cost $40 million (Dh146m) to build, will convert the waste of more than 550,000 residents in the UAE. 
The facility was built as part of a joint venture with the Ministry of Climate Change and Energy and Ajman Municipality to improve the UAE's waste management and it is the first of its kind in the Arabian Gulf.

It contributes to the UAE's strategic objective of landfill diversion of least 75 per cent by 2021.

How is waste converted to fuel?

Two conveyor lines will treat more than 350,000 tonnes of waste a year at the plant and the materials pass through a number of different processes before being converted into the fuel

“We have an industrial shredder that cuts almost any solid waste, from steel to a double bed and wardrobe, into 90mm by 90mm pieces,” said Mr de Koning.

“Large magnetic drums segregate ferrous [iron containing] and non-ferrous metals, and they are then separated from the rest of the waste as they cannot be used as high calorific fuel [ [better heating value] for burning.”

Air classifiers then push high-pressured air in the waste and non-combustible parts, such as stones and wet organic waste like banana skins and orange peels, are taken out. “They just don’t burn well so we have to separate them,” said Mr de Koning.

“What we’re then left with is a fluff of combustible components which is our end product, the fuel.

“The best materials for this type of fuel are paper, plastic, cardboard and woodchips.”

If you take one unit of energy [a megajoule] coming from RDF, it should always be cheaper than the same unit of energy coming from coal, said Mr de Koning.

While 80 per cent of the waste is turned into fuel on site, about 15 per cent goes to landfill and the remaining five per cent – mainly metals – are sold off.

What materials are used? 

A laboratory on site allows technicians to check the quality of the RDF before sending it out to factories. Chlorine content, calorific value and moisture are all measured against an industry standard. “The chlorine content has to be under one per cent," said Mr de Koning.

"So far, our material is measuring in at about 0.6 per cent, which is encouraging.

“With our RDF, we are promising 15 megajoules of energy per kilo and the less moisture the better, we aim for under 20 per cent.

“We tend to take out organic materials like food scraps as they have a high moisture reading.”

By implementing this project, approximately 80 per cent of household waste in Ajman and Umm Al Quwain will be diverted from landfill. It will partially contribute to the replacement of traditional fuels such as gas or coal.

The National photo project

Chris Whiteoak, a photographer at The National, spent months taking some of Jacqui Allan's props around the UAE, positioning them perfectly in front of some of the country's most recognisable landmarks. He placed a pirate on Kite Beach, in front of the Burj Al Arab, the Cheshire Cat from Alice in Wonderland at the Burj Khalifa, and brought one of Allan's snails (Freddie, which represents her grandfather) to the Dubai Frame. In Abu Dhabi, a dinosaur went to Al Ain's Jebel Hafeet. And a flamingo was taken all the way to the Hatta Mountains. This special project suitably brings to life the quirky nature of Allan's prop shop (and Allan herself!).

Labour dispute

The insured employee may still file an ILOE claim even if a labour dispute is ongoing post termination, but the insurer may suspend or reject payment, until the courts resolve the dispute, especially if the reason for termination is contested. The outcome of the labour court proceedings can directly affect eligibility.

Expo details

Expo 2020 Dubai will be the first World Expo to be held in the Middle East, Africa and South Asia

The world fair will run for six months from October 20, 2020 to April 10, 2021.

It is expected to attract 25 million visits

Some 70 per cent visitors are projected to come from outside the UAE, the largest proportion of international visitors in the 167-year history of World Expos.

More than 30,000 volunteers are required for Expo 2020

The site covers a total of 4.38 sqkm, including a 2 sqkm gated area

It is located adjacent to Al Maktoum International Airport in Dubai South

How Alia's experiment will help humans get to Mars

Alia’s winning experiment examined how genes might change under the stresses caused by being in space, such as cosmic radiation and microgravity.

Her samples were placed in a machine on board the International Space Station. called a miniPCR thermal cycler, which can copy DNA multiple times.

After the samples were examined on return to Earth, scientists were able to successfully detect changes caused by being in space in the way DNA transmits instructions through proteins and other molecules in living organisms.

Although Alia’s samples were taken from nematode worms, the results have much bigger long term applications, especially for human space flight and long term missions, such as to Mars.

It also means that the first DNA experiments using human genomes can now be carried out on the ISS.
