NATURAL RESOURCESThe predominant raw non-renewable resources used on the site are:oil, water and electricity. Consumption figures for 2005/06 are:Oil: 287,380 litres Water: 2,557 m 3Water UsageWater meter readings have remained high during theperiod 2005–2006. This is again an increase on theprevious reporting period.There are two reasons for the increase in usage.Firstly the consequence of operating the Odour Controlsystem has undoubtedly lead to an increase in waterusage. This type of equipment is used to negate theeffects of odour permeating from the site and causing anuisance to our neighbours. Therefore, we must attemptto balance the operational demand on water usageagainst the potential for causing a nuisance to ourimmediate neighbours. The odour control equipment inplace at Redhill allows us the option of restricting the flowof the system. This is achieved by selecting which points ofthe compass are considered the most sensitive and settingthe system to operate automatically when the wind isleast favourable. We also have the option to operate thesystem on a pulse setting that remains effective butreduces the demand on water supply. We will continue tomonitor water usage and liaise with the supplierregarding the results.Secondly; changes to operational practices brought aboutby increasing legislation, have tended to have a negativeimpact upon water consumption.In the coming months we will be investigating greater useof the naturally occurring water sources on the site to seeif these can be utilised to lower imported waterconsumption.Gas Oil UsageGas oil usage is also on the rise and this can beattributed to changing operational practices, such as ourclients utilising bigger vehicles to bring waste on to thesite. This in turn means we need larger compactors andother plant to enable us to efficiently and safely dealwith these larger loads.The benefits of employing larger machines far outweighsthe extra fuel consumed, in terms of customer satisfaction,where operating standards have improved and not least,better waste compaction and therefore a saving inlandfill void space.Electricity UsageAs part of the redesign of the lower quarry access andpumping configuration, two electric pumps werecompletely decommissioned and following refurbishmentof the remainder only two are now required onpermanent duty. This leaves two on standby with adownward trend in electricity consumption.In the future there will be an increasing demand forelectricity as additional phases of Redhill 2 becomeoperational. We will however endeavour to utilise energyefficient measures to control future consumption ofelectricity.3031
BIODIVERSITY &RESTORATIONBiodiversity is described in the Government's UK Biodiversity Action Plan as“the variety of life forms that we see around us. It encompasses the wholerange of mammals, birds, reptiles, amphibians, fish, insects and otherinvertebrates, plants, fungi and micro-organisms”. During 2002, as an initialpilot, we assessed the biodiversity of Redhill landfill site. From this assessmentwe established a formal Biodiversity Action Plan (BAP) to manage thebiodiversity of the site.Over the past five years the majority of Redhill 1 hascome to completion and it’s attained final restorationprofiles. These areas have now entered into formalaftercare status.At Redhill the completed areas of the site are used forthe grazing of livestock and the collection of a crop ofhay in early summer. Tree planting is something that wetake very seriously, over the past five years in excess offive thousand trees have been planted at variouslocations throughout the site. Species of tree and shrubare selected to be sympathetic to the locality.The redesign of Redhill 2 following the approval ofplanning application in 1998 necessitated the creation ofa soil embankment around the Northern extent of thesite. Construction of the embankment took place withinthe flood plain area and therefore compensationmeasures were necessary. Two locations were identifiedas suitable and with sufficient area to compensate for theloss of flood plain. Firstly a small area immediately to theNorth of the embankment was chosen as compensationarea 1, followed by a larger off site area 2. The latter iswithin our ownership yet outside of our normal area ofoperations on a site used primarily for grazing livestock.The chosen areas were reduced in height by the removalof topsoil, which was placed in a temporary stockpile,allowing the lower subsoil to be relocated outside of theflood plain, and then the topsoil was replaced to create abowl effect for the collection and storage of water.The affected areas when completed were sown with agrass meadow seed type, again sympathetic to the area.Our new surface water lagoon continues to develop andattract wildlife, as the harsh contours of construction areeroded by the colonisation of aquatic plants andanimal life.Situated to the extreme North East of Redhill landfill is thesite orchard, here are grown many different varieties ofapples and some that originated locally in Surrey.Planting of the orchard was funded by Biffa but cared forby local volunteers, who diligently tend the trees year onyear and hopefully enjoy the fruits of their labours beforethe least scrupulous members of the community get tothe crop.3233
