Waste Carriers
 

The requirement to register as a carrier/broker of controlled waste is contained within “The Control of Pollution (Amendment) Act 1989” and “The Controlled Waste (Registration of Carriers and Seizure of Vehicles) Regulations 1991”. These require that any person who transports/makes arrangements for management of waste in the course of any business without being registered with the appropriate registration authority commits an offence, unless they are exempt. KCP have identified that this is of great importance for our successful operation particularly on closed landfill sites. Issues with desilting and jetting etc are still required on these sites, which by their nature no longer have a licence for the disposal of waste. Therefore any debris that we remove has to be safely transported and disposed in accordance with the The Controlled Waste Regs. As well as off site disposal of landfill leachate and silt, we have also been involved with industrial tank cleaning containing materials used for preservation of timber. The procedures for all activities regardless of the nature of the waste remains the same and KCP are able to identify suitable disposal routes for all.

 Moving Forward
 

All technology moves forward as one successful application leads to the formation of other theories etc etc. The current theory on cell basal pipework located in landfill sites is that this should be readily accessible for jetting, CCTV and general maintenance. This is one theory that provides a number of other issues that will affect the overall performance and functioning of the landfill as it is intended, a disposal point for refuse and unwanted material. Our application of jetting capabilities will ensure that as far as practicably possible these lines will be able to be jetted and maintained. Having reviewed and commented upon some designs we are confident that generally the designs can be maintained by the services we provide. However as to maintenance of all structures within the landfill cell, we have to ask the question why. In general civil engineering terms this is termed as the rehabilitation of the pipes, which sets out to achieve one or more of the following; restore structural integrity, prevent leakage, prevent corrosion, improve hydraulic performance. Generally in achieving one of the above another parameter is achieved. What has to be answered is: - are we intending to improve the hydraulic performance of the pipes? If so surely there are other more sustainable answers to be investigated. The surface area of basal pipework relative to the overall cell base may vary from say 1 to 5% of the overall drainage area. What purpose does it serve if the pipework located within a 500mm drainage layer and located beneath circa 15 to 40m of waste is clean and allowing free passage of leachate? Concentration on the media used and its sustainability in the other 95% of the available surface area would ensure overall, that gravity flow of leachate would be maintained.

As regular desilting and jetting of all pumping and extraction points will improve performance at the critical points.
