The Institute of Waste Management of Southern Africa (IWMSA)’s Landfill Interest Group (LIG) in KwaZulu-Natal, proudly announces its Ninth Biennial Seminar on Landfills, Landfill 2011, to be held from 18 – 20 October 2011 at Docklands Hotel, Durban.  The LIG is dedicated to capacity building and technology transfer in the science and practice of waste disposal by landfill.

The prime focus of modern waste management lies in reducing the amount of waste going into landfill sites however, the application of this strategy is slow in coming about. Existing landfills, of which there are approximately 1,200 in South Africa at present, are being scrutinised ever more closely and the development of new facilities is becoming increasingly challenging as the old ones are filled up.  Stan Jewaskiewitz, President of IWMSA says “Reducing waste to landfill is essential, however, landfilling and landfill treatment facilities are set to remain an important waste management option into the foreseeable future.”

Landfill facilities, now more appropriately known as ‘waste management facilities’, remain plagued by many problems related to technology, including leachate and biogas emissions.  The LIG Landfill Seminar series is designed to create a low-cost forum where a high standard of knowledge transfer may be experienced – with the focus firmly on landfill issues and new technologies rather than on waste management in general.

The themes for Landfill 2011 will include design, construction, and operation of landfills on challenging environments including landfill barrier design and performance. Landfill policy and legislation, is a key topic that will be discussed and guidelines for both National and Provincial regulation and planning requirements will form part of the discussions. Sustainable landfill concepts for municipal and hazardous waste; landfill processes and emissions including leachate and gas management and waste mechanics will also be discussed during the Seminar. Other important themes include landfill remediation, aftercare and reuse as well as investigating alternative technologies.

Delegates attending Landfill 2011 can look forward to a keynote address by Kelvin Legge, Chief Engineer, Integrated Environmental Engineering of the South African Department of Water Affairs.  Legge is an international authority on fluid migration through soils and geosynthetic materials, and appropriate contaminant containment standards for the new national revised waste classification system. Legge’s focus at the Seminar will be on the new landfill classification system which will have a direct impact on all stakeholders that are involved with landfills.

Also on offer is a half-day workshop on lining design and landfill stability which will be facilitated by an international expert on the subject, Richard Thiel of Thiel Engineering, California. The cost of bringing Thiel to South Africa has been sponsored by the LIG’s partners, the Geosynthetics Interest Group of South Africa (GIGSA), thus assisting the LIG to adhere to its mandate of providing affordable specialist landfill seminars.

Landfill 2011 aims to continue the highly successful seminar series as run over the last 18 years by the IWMSA LIG and in 2011 this event has been made possible by a generous grant from Messrs Barloworld Equipment.
