The Msheireb - Heart of Doha project is designed to accommodate an estimated population mix comprising 2,226 residents, 2,930 retail employees, 12,286 offices employees within an area of 303,243 sqm of residential floor space, 253,906 sqm of commercial area and 151,611 sqm of hotel and amenities areas.
As each occupier and transient equivalent will generate various types of waste, it is designed to segregate and collect waste in three fractions; comprising of organic, residual, and recyclable refuse. The segregated waste streams will be separately collected and transported to a waste collection facility, via a unique horizontal vacuum pipe network system.
In order to keep the waste fractions separated, each waste type must be sorted correctly when it is disposed into the system from source, therefore in each outdoor location there will three separate inlets that will allow the occupant and transient to dispose into the correct waste type inlet.
The installation of the Automated Waste Collection System is expected to handle about 184 m3 per day or 27.6 T/day with a specific weight of 150 kg/ m3 for residual waste, 100 kg/ m3 for recyclable and 250 waste density for organic/wet fraction. This volume of waste will be generated by 2,226 inhabitants and 405,517 m2 of commercial areas including retail shops, restaurants, public areas, hotels, offices and school.
Due to size of the project and the constraints in handling the waste both in terms of volumes, distances and number of inlets, One (1) Automated Collection Stations is proposed with 3 waste container in order to have enough capacity to accumulate one day waste generated in all phases. 3 additional containers have been provided one for each fraction.
Envac ME won this tender which was a global bid against our competitors from Europe, Asia and Korea. Envac was also awarded the O&M contract.
This project is unique as this will be the first project in the ME with a access card readers, weighing mechanism incorporated in the inlet doors which will weigh and dispose the waste and also have a record of all users and waste disposal transactions.
Mohammed Al-Marri, Projects Director of Msheireb Properties said, “The Gulf’s remarkable growth story has also affected the environment to a degree, which is why offsetting the impact of any development is at the heart of Msheireb Properties’ vision. With this system from ENVAC, combined with an education campaign for all residents, we can ensure Msheireb Downtown is at the forefront of the world’s ‘Green cities’ movement.
That aspect of education is critical to getting the most out of this system. Recycling, however, still isn’t necessarily upper-most in people’s minds, which is why we in partnership with ENVAC are also putting together a program which will put in place workshops on how to use ENVAC, as well as organizing visits to the collection centre to see how the waste is collected and segregated.
We are confident that through education programs such as these, future residents of Msheireb Downtown will make the neighbourhood’s green credentials a real point of pride.”
