Public and private sector experts to share waste management best practice

The first edition of EcoWASTE, the dedicated waste management and recycling event in the Middle East, will gather the insights and practical experience of a host of leading companies, institutions and industry experts from January 20-22 in Abu Dhabi.

The inaugural event will organise a series of technical workshops and presentations from the exhibition floor on subjects spanning recycling, waste-to-energy and waste collection, with contributions from experts based as far afield as Finland and the UAE.

“Our first EcoWASTE sheds further light on the interrelated challenges of energy, water and waste,” said Naji El Haddad, EcoWASTE Show Director. “Through these sessions, attendees will not only network with more than 50 local and international suppliers as well as 2,000 buyers and professionals from across the waste management and recycling sector, they will also gain in-depth knowledge from technical experts at the forefront of sustainable waste management regionally and internationally.”

With several GCC states embarking on projects in waste-to-energy, the Swedish Waste Management Association will deliver its assessment of the potential to generate clean power from the substantial volumes of municipal solid waste currently dumped in desert landfills across the region. In Sweden, as much as 97% of all household waste is recycled or used to generate energy.

Eric Lindström of Capital Cooling will present on waste heat as a power source for cooling, based on insights from his native Sweden and the GCC.

Also at EcoWASTE, Dr Johan De Greef of Keppel Seghers, will consider waste-to-energy solutions tailored for the industrial sector. Keppel Seghers designed and built the GCC’s first domestic solid waste management centre, or DSWMC, in Qatar, which diverts up to 95% of waste from landfill. The DSWMC comprises a state-of-the-art waste sorting and recycling facility, an engineered landfill, a composting plant, and a waste-to- energy incineration plant with a capacity of 1,500 metric tons per day.

With more than 10 million metric tons of municipal waste produced each year in Abu Dhabi alone, advances in waste collection technologies and services will be top of the agenda. EcoWASTE will host a seminar on automatic solid waste collections systems by Jari Enontekiö of Marimatic Oy.

“The GCC has the potential to become a leader in the waste-to-energy sector as the DSWMC in Qatar illustrates,” said Dr Johan De Greef of Keppel Seghers. “With Abu Dhabi aiming to divert 85% of its solid waste from landfill by 2018 and other states in the region following its lead, the technology and insights presented at EcoWASTE provide a pathway towards a genuine sustainable waste management future.”

A chilling reduction

The Regulation and Supervision Bureau (RSB) is the independent regulatory body for the water, wastewater and electricity sector of Abu Dhabi. Through unique initiatives to collect and share information, RSB’s Powerwise office works to create understanding and awareness of the critical issues surrounding the consumption of electricity and promote sustainable consumption. The Bureau’s ongoing energy efficiency projects include the time-of-day trial and AC chiller control demand side management pilot project. Ramiz Alaileh, Powerwise Manager at The Bureau spoke to Anoop K Menon about these projects and why they constitute an essential step towards shaping the Emirate’s future energy roadmap

Could you tell us about the current status of AC chiller control?
The AC chiller pilot project aims to test the technology of remotely controlling air conditioning chillers of high-rise buildings and office towers in Abu Dhabi. The main purpose is to test this technology in the local environment of Abu Dhabi, where the air conditioning load is about 65% of the total electricity summer demand, and to record the resulting reduction in summer peak demand.
The pilot project was divided into four phases. In the first phase, also called the pre-construction phase, we surveyed 15 buildings in Abu Dhabi, a mix of commercial, residential and office buildings, mid-rise to highrise to study and choose the best five for the pilot. We selected the final five buildings on the basis of the good condition of their chillers, proper insulation, and the building not being negatively pressurised. We also wanted to make sure that we have a combination of different chiller manufacturers.
During the second phase, which was the construction and design phase, we looked at the initial design of the controllers that would be mounted on top of the chillers. We studied controlling the chillers by limiting the current to the chillers, and at the same time, getting realtime information from the buildings about CO2, temperature and humidity levels. We also made sure that differential pressure in the building doesn’t get altered. Apart from chiller operation per se, we also took into account fresh air handling units in the design.
In the third phase, we built and installed the controllers in the buildings, and carried out initial testing to ensure they are working properly.
We have entered phase four of the pilot, where we have started running the chillers through controllers that are operated remotely through a dashboard in our offices in Sowwah Square. Of the five buildings in the trial, three are located in Abu Dhabi Island and two are in Mohammed Bin Zayed City. We communicate with the controllers wirelessly or through wired (fibre) network. We get realtime data about the actual chiller loads, actual temperature and humidity. At the moment, we run the chillers in these five buildings on a daily basis from 1pm to 4pm. Our focus is on optimising the chiller demand in these buildings during the peak period.

Are there initial findings that you could share?
In one of the installations, over the three hour operating period, we were able to shave between 20-40%. When we calculated the true savings or overall savings during this period, we found it to be around 750 kW/h.
In the first hour, when we trigger the DSM chiller, we cap the baseline current and from there, reduce 20% in terms of the set-point that is sent to the chiller. This set point lasts for one hour and usually, the chiller current will follow through the controller. At the start of the second hour, we bring it down by another 40%, and that continues for another hour. We release 20% for the third hour and at the end of the hour, disable the DSM. During this period, we monitor Indoor Air Quality (IAQ), temperature and humidity. Temperature has changed from 21.5 degree C to 24 degree C while humidity changed between 60 -70%.
The building occupants are unaware about the pilot, and we prefer it that way to prevent any psychological impact on them. During the trial period, we have received only one complaint so far.
Phase 4 of the pilot will run until the end of next year. We could only capture part of the summer last year but in 2014, we plan to capture the whole summer. Based on that, we are going to run a study on the impact of the project in reducing peak demand during summer or hot/humid days. Humidity is a big challenge but so far the results have proven to be positive.
Again, we are trying to run this pilot as a proof of concept. If this proof of concept turns out to be a viable economic solution, we may take it forward with other stakeholders to prepare the ground for a bigger roll out.
In the trial, we have confined ourselves to existing buildings where the focus is on retrofitting and interfacing with existing AC chillers. The option for new buildings in the future could be having the controllers as a built-in feature in the chillers when designing and installing a cooling system.

How does this pilot align with what is happening in terms of smart grid?
What we are doing in terms of DSM in this project is trying to shave peak demand. In other jurisdictions, these peak demand resources (they are called resources because you can shave them) are integrated into the utility SCADA, EMS or Smart Grid systems. The utility will be able to take them into account resources when it wants to carry out peak shaving.

What are the initial findings of ‘Time-of-Day’ trial?
We have initiated the final phase of time of day trial where the objective is to understand over a period of time and in the absence of financial incentives, whether education and information can induce and sustain positive behavioural change in terms of reducing energy consumption.
During this phase, which will run till October 2014, time of day pricing will be switched off but participants will maintain the Customer Display Unit (CDU) in their premises to track their electricity consumption based on the standard tariff.
In parallel, we are kicking off a thorough study of existing data that we have collected over the past nine to 12 months. This includes pre-trial time-of-day pricing and during timeof- day pricing data. In this study, we are looking at the impact of the trial – how much we have been able to reduce overall consumption and how much the participants were able to shift from peak to off-peak.
Initial findings show that the trial was well received. Around 65% of the participants were able to save on their consumption. We have also seen 10% peak to off peak shifting compared to similar premises. We have appointed a third party organisation to analyse the data and advise us on the results.
We plan to release the findings during the International Water Summit (IWS), which will held in January 2014 as part of Abu Dhabi Sustainability Week (ADSW).

Are there any more of such initiatives in the pipeline?
In fact, we ran a highly successful summer awareness campaign this year where we interacted directly with the consumers. PowerWise interactive game is our flagship awareness platform to engage with consumers. We are always keen to learn and utilise technology as a tool to engage with the customers. The interactive game was used as part of our summer campaign in select malls in Abu Dhabi and Al Ain. The players competed against each other to gain the highest score in a race against time, to make the best decisions on how to save water and electricity. The initiative was well received with over 1,000 visitors trying the game.
The game is hosted on our website as well, and players can now share the results over social media. We are continuing to look at different options like web apps to engage with consumers. This is an integral part of our overall strategy of influencing consumer behaviour to encourage wise use of electricity.

All these initiatives impact consumers, directly or indirectly. What is your perception of consumer behaviour in the region with regard to energy conservation? Do they really care or are they helpless in terms of not being able to do what they wish to? Or is it that they are aware but don’t feel compelled to act?
Different consumer segments look at this issue differently. If we take our summer campaign as an example, it definitely struck a chord with consumers and received a lot of positive feedback. I firmly believe that awareness is not a oneoff thing, it has to be continuous and sustained. We have to engage with customers in innovative ways without overwhelming them with conservation messages. This should be done in an acceptable and fun way to achieve the best results.
Another initiative we launched last year in collaboration with Abu Dhabi Water & Electricity Authority (ADWEA) and the two distribution companies – Abu Dhabi Distribution Company (ADDC) and Al Ain Distribution Company (AADC) – was the ‘Are you in the Green or the Red’ campaign. The tool we used was re-designed utility bills that informed customers about whether their consumption fell in the green (ideal average) or red (above ideal average) as well as government subsidy that masks the actual cost of water and power.
When we did a study on the impact of this initiative, the feedback again was very positive. Some people were questioning why are we in the Red? We need to be in the Green. It has proved to be a very simple and effective way to engage with the consumers and entice them to do something about conserving electricity and water. In fact, many people didn’t know that subsidy existed. By saving electricity, you save on your utility bills and you also help the country. It has proved to be a simple yet effective measure in terms of creating awareness.

IDA supports IWS as a knowledge partner

For the second year, the International Desalination Association (IDA) is supporting the International Water Summit (IWS) as a Knowledge Partner. IDA focuses on desalination and water reuse, and has organised several sessions that will be presented at the Summit – a unique platform for promoting global collaboration on water sustainability to be held January 20-22 at ADNEC.

With IDA’s support, IWS aims to open new opportunities for global leaders, scientists, innovators and environmental experts to work together to make recommendations and improvements within the desalination industry.

The desalination sessions organised by IDA will provide insights on enhancement of energy efficiency in the desalination process including discussions on low energy desalination technologies and their strategic selection with special focus on the GCC region and the evaluation system.

Dr Abdullah Al-Alshaikh, IDA president and deputy governor for Planning and Development of Saline Water Conversion Corporation (SWCC), said: “In the last 20 years, the evolution of desalination technologies has significantly reduced energy consumption and the cost of water. Technological innovation – from growth in new technologies to development of renewable sources of energy to power desalination – is the key factor in optimising water and energy costs worldwide. Increasing energy efficiency remains a goal for the industry as we chart the course to sustainable desalination.”

Dr Al-Alshaikh will expand on this topic during his keynote remarks on “Sustainability: The Driver of Innovation” on January 21.

Leon Awerbuch, director of IDA and president of Leading Edge Technologies, said: “Some countries in the Gulf rely on desalination to produce 90% or more of their drinking water, and overall this region represents nearly half of the world’s desalinated water capacity.”
Awerbuch will address the conference on evaluating different desalination technologies and will lead the panel discussion on strategic technology selection.

Miguel Angel Sanz, 2nd vice president of IDA and director of development and innovation at Degrémont, will speak on the subject of energy conservation through reverse osmosis desalination. His speech will highlight the importance of considering both water and energy in tandem rather than in isolation – a key platform of IWS and the primary reason for its co-location with the World Future Energy Summit (WFES) for the past two years.

Dr Corrado Sommariva, past president of IDA and managing director of ILF Consulting Engineers, will speak on renewable energy desalination at the Summit. He is a technical adviser for the new desalination plant being constructed in Fujairah. The plant is a benchmark of new energy efficiency standards as it will produce 3.7 kilowatt hours per cubic metre as compared to the industry standard of 4-6 kilowatt hours per cubic metre.

According to IDA, the GCC region is the world’s largest producer of desalinated water. Saudi Arabia is the largest country producer, producing 9.2 million cubic metres per day. The UAE is the second largest producer with a daily production rate of 8.4 million cubic metres.

Global Water Intelligence/DesalData estimates that the total value of desalination contracts awarded in the GCC in 2013 was approximately $2.7 billion, relating to 1.9 million m3/d of additional capacity. Over the next five years a further $11.7 billion is expected to be spent on desalination plants in the region, adding a total of 8.4million m3/d of new capacity.

Regulation and Supervision Bureau to participate in IWS 2014

The second International Water Summit (IWS), a platform for promoting global collaboration on water sustainability to be held on January 20-22 at ADNEC, has confirmed the participation of Nick Carter, Director General of the Regulation and Supervision Bureau, in one of its highly anticipated panels.
Entitled ‘Water Security and Future Water Sustainability’, the panel discussion will highlight future opportunities for the UAE and discuss how improved water sustainability, regulation, technology and governance will enable the region to keep pace with commercial development and population growth.
As the independent regulator of the water sector in Abu Dhabi, the Bureau plays a crucial role in the sustainability of the sector. This includes collaborating with a number of government and operating company stakeholders to make sure there is a coherent and integrated water strategy, capable of effectively managing desalinated, recycled and ground water.
Carter said: “We have issued regulations to ensure that recycled water from Abu Dhabi’s wastewater treatment plants is used effectively, safely and in applications appropriate for its quality. Other stakeholders, including the Abu Dhabi Environment Agency and the Food Control Authority are working with sectors such as agricultural and farming communities looking at best practice in irrigation technology and crop selection, reducing the pressure on native aquifers and water resources.”
The Bureau’s Powerwise and Waterwise offices, launched in January 2013, champion effective water and electricity consumption in Abu Dhabi. “Through research and studies we are gathering high-quality data to better inform targeted campaigns for both domestic and non-domestic settings and to set policies in the future. We also partner with other government entities and sector stakeholders to put strategies in place that will promote an efficient water and wastewater sector. For instance, new buildings now have water-efficient fittings and the new water and electricity bills, launched in 2012, provide detailed information about consumption and the level of government subsidy.” added Carter
“Awareness of the critical issues surrounding the use of drinking water and education are crucial to the sustainable availability of this precious resource. Understanding its true value is key, especially when promoting the wise use of resources and in this regard we are winning.”

Youth awarded for innovation at the WFES and IWS

With sustainable development being an important challenge for future generations, the Green Ideas Expo awards, organised in partnership with Abu Dhabi Water and Electricity Authority (ADWEA) and conducted during the 2013 World Future Energy Summit and the International Water Summit, hosted by Masdar, will go a long way to ensuring that the youth of the region are actively involved in developing solutions for a greener, cleaner world.

 The Green Ideas Expo coincided with global celebrations for the 2013 International Year of Water Cooperation, and the aim of the awards was to encourage young people to develop innovative solutions for regional and global water and energy challenges. The winners were decided by the highest votes received from visitors during WFES and IWS 2013.

The team of Anjania Malpani, Dahrof Pakashi and Abhidi Soryeaih was awarded first place, with Omar Al Ameri and Sultan Al Kaabi, two Emirati students with scholarships from ADWEA, coming in second place and third place respectively.

Explaining the idea behind the winning project, Anjania Malpani said: “The idea was to turn mechanical power into electricity by walking on certain materials such as crystal in what is called pressurized electricity. The team will initially adopt this idea at Dubai Airport and Abu Dhabi Airport which witness a high percentage of passenger traffic”.

Runner-up Omar Al Ameri said: “My project was to produce water and electricity from heat extracted through deep wells from the ground where temperatures reach 300°C. After digging the wells, a liquid is extracted and then injected into a desalination plant to produce water and electricity. This project does not require any fuels and unlike solar power, which is available only at daytime, it can be carried out any time throughout the year”.

The winning team received a cash prize of US$2,000, with the second place receiving US$1,000, and the third place receiving US$500.
