Global
Waste Management Project Profiles

 

With so many people now living in cities, increasing volumes of waste are becoming a headache for town planners, developers and local authorities. In order to combat this and continue the sustainable growth of cities, governments have to adopt more original thinking for the recycling and disposing of waste. Below is a list of the 10 most innovative recycling and waste management projects as chosen by a panel of independent industry professionals for the Infrastructure 100: World Cities Edition.

 


 

Feature Project: Deep Tunnel Sewerage System

 

The Deep Tunnel Sewerage System in Singapore has been under construction since 2000 and is scheduled for completion in 2020. The massive scheme has been designed to address all of the city-state’s long-term needs for used water collection, treatment, reclamation and disposal. The award-winning system works entirely by gravity, thus eliminating the need for pumping stations and the risks of used water overflows as well.

Askar Waste to Energy PPP

 

The Askar Waste to Energy PPP in the Kingdom of Bahrain has the potential to be a pathfinder for both the country and the region. As a Public Private Partnership (PPP), the US$480 million facility is being commercially financed amidst a global debt crisis with uncertainty created by the Arab Spring and sporadic civil unrest. The need for the project is great as it aims to tackle the Kingdom’s growing problem with waste management by providing capacity to treat 390,000 tons of domestic waste per year from Manama, the country’s capital and largest city. In addition, the facility – located in the village of Askar on the south eastern coast – will generate 25MW of power fed into the grid.

Yas Island Waste Management System

 

The Yas Island Waste Management System in Abu Dhabi is set to revolutionize the country’s recycling industry with its state-of-the-art vacuum waste management system. The system is capable of handling 40 tons of rubbish from 43 collection points transported through 5.3 kilometers of pipelines at speeds up to 75 kilometers per hour. The scheme will serve Abu Dhabi’s popular tourist destination which includes the artificial island’s famous Formula One racetrack, nearby Ferrari World, the marina and seven hotels. The system will reduce the need for garbage trucks by as much as 90 percent, thus reducing traffic on the roads and cutting CO2 emissions.

Gorai Dumping Ground Scientific Closure

 

Judges were impressed with the initiative being used in the Gorai Dumping Ground Scientific Closure to address a common challenge in the region. The unappealing but essential project is a PPP to renovate an area of Mumbai which had been used as a major dumping ground for waste. The site spans 19.6 hectares and has been operational since 1972. The closure has had a major social impact as the dump was located next to residential areas, posing health risks and contaminating local water supplies. Closure of the site in 2009 involved reforming the existing heap and sealing it off with impermeable surfaces. There are now plans to install a power plant at the site which will run on methane gas generated by the decomposing rubbish.

Bordo Poniente Waste to Energy

 

In December 2011, Mexico City closed the Bordo Poniente dump, one of the world’s largest waste sites. Since 1994, it is estimated that 79 million tons of garbage were dumped in the landfill. Since its closure, a sizable waste-to-energy scheme has been developed to capture the methane gas produced by the landfill, which will be used to power as many as 35,000 homes when complete.

Bio-Cancun Project

 

The Bio-Cancun Project on the Yucatán Peninsula is another waste-to-energy scheme developed through international cooperation which facilitates the transfer of technology. A combined effort in 2009 between the Canadian and Mexican governments, the project aims to divert organic matter headed for landfill sites in Cancun to a bio-digester for treatment. By-products of the scheme include fertilizers for agricultural use and biogas to generate power.

The Energy Garden Project

 

Harvest's Energy Garden in Richmond, outside of Vancouver, is the country's first high-efficiency system for producing renewable energy from food scraps and yard trimmings. The project uses a number of different funding sources including a $4 million grant from Natural Resources Canada (NR-Can) and will process more than 27,000 tonnes of food scraps and yard trimmings per year diverted from British Columbia landfill sites. The site will power more than 700 homes and also provide high-quality compost for local farms and gardens.

Durham York Energy Waste Project (DYEC)

 

The Durham York Energy Centre (DYEC) is another world-class energy waste facility being built in Canada. The DYEC will process remaining residential waste following Durham and York’s aggressive composting and recycling programs, while also recovering metals and energy. Durham York Energy Centre will have a maximum capacity of 140,000 tonnes per year.

Zero Waste: Edinburgh and Midlothian

 

The Zero Waste: Edinburgh and Midlothian project in Scotland impressed judges as the project has been developed in response to the Scottish Government’s Zero Waste Plan in 2010. It aims to separate all food waste collections from regular rubbish by 2013 followed by a ban on recyclable waste in landfills by 2015. The project involves development of an anaerobic digestion facility to process 30,000 tons of waste per annum.

Tonsberg Waste to Energy PPP

 

The proposed Tonsberg Waste to Energy PPP will serve one of the oldest towns in Norway. This project is another strong example of a city using a PPP to manage waste and put it to a productive use. The project will help Tonsberg and other municipalities in Vestfold County to convert sewage sludge, food waste, organic commercial waste and manure into biogas which will then be used for heating and electricity production. The council also expects to use it for running buses which currently use about four million gallons of gasoline/diesel per year.
