Recycling Plant in Dubai for Commercial Waste from the World's Largest Offshore Industrial Park
Realized by Eggersmann Anlagenbau
Waste is a global problem that is growing every day, and with it landfill sites that produce CO2 and methane. It is a disaster for the environment and climate change. In Dubai, however, they are getting to grips with this problem and Eggersmann Anlagenbau was commissioned with the engineering planning and construction of a recycling plant for industrial, commercial and household waste. The opening ceremony of the Farz plant took place on 3 February, 2020 in the presence of the Minister for Climate Change and Environment of the United Arab Emirates, Dr. Thani bin Ahmed Al Zeyoudi.
The original contract for future cooperation between the clients Ramky Enviro Engineers Middle East and Eggersmann Anlagenbau was signed in December 2017. In addition to engineering design and planning, the scope of the order also included the procurement, manufacture and delivery of the entire plant technology and components as well as assembly and commissioning. The official acceptance and handover took place to the agreed schedule in December 2019. The plant is operated by Farz, a joint venture between Ramky and Imdaad.
The waste recycling plant in Dubai was designed for a throughput of around 700 tonnes of commercial waste and 500 tonnes of household waste per day. The day to day industrial and commercial waste from the world's largest offshore industrial park, Jafza Jebel Ali Free Zone, is processed here in three stages. In addition, the majority of the waste from the WORLD EXPO, which will take place in Dubai from October 2021, is to be treated in the recycling plant.
In the material receiving area of the 2-line plant, the material composition is assessed to determine whether the material must be pre-sorted as a first step or whether it can be forwarded directly for processing in the plant. With commercial waste, pre-shredding is imperative due to the large number of bulky solids. Two Eggersmann TEUTON shredders are in use around the clock and process a total of around 1,200 t per day before passing on the material to the trommel screens that are also supplied by Eggersmann. The screening operation is followed by separation of ferrous and non-ferrous fractions as well as the sorting of plastics, cardboard and paper with NIR devices. Eggersmann ballistic separators then split the plastic fractions into flat and three-dimensional parts. Other infrared devices sort the three dimensional plastics into PET and HDPE.
The recycled fractions of PET, HDPE, paper, cardboard, ferrous and non-ferrous are then pressed into bales and returned to the material cycle. The residue fine waste fractions are pressed into containers for subsequent disposal to landfill. The remaining high calorific value fraction is supplied to cement works for use as an alternative fuel (RDF).
With the new recycling plant, Farz is setting a vital example in respect of climate protection. The waste process, allows valuable recycling fractions of about 25 - 30% to be recovered, which correspondingly relieves the current landfill. The emissions of CO2 and CH4 also lowered considerably. At the same time, RDF is obtained, thus reducing the use of fossil fuels in the cement plants.
“The implementation of this system is particularly important to us. As part of the material receiving area and recycling plant hall, a control room with 5m high glass panoramic viewing panes and a visitor room have been created, in order to receive, train and make visitor groups aware of the issue of recycling.
In order to allow for future options, there is an area for expansion on the plant site for a second plant of the same size,” commented Ramky Group Managing Director, M. Goutham Reddy.
