Furtherwick Park SchoolA specialist College for the Media Arts Partners for Success : 1 Furtherwick Park SchoolA specialist College for the Media Arts Partners for Success Environmental Conference 2008 Berlin Waste management By Aaron Acraman, Sean Clow, Lewis Lacey Furtherwick Park SchoolA specialist College for the Media Arts Partners for Success : 2 Furtherwick Park SchoolA specialist College for the Media Arts Partners for Success Visit to Veolia Waste Management Facility at Pitsea on 23 Jan 2008 Furtherwick Park SchoolA specialist College for the Media Arts Partners for Success : 3 Furtherwick Park SchoolA specialist College for the Media Arts Partners for Success Six students from the school visited the Veolia Waste Management and Landfill site The Manager (Special Projects) Nick Walker was our host and gave a very detailed overview and site visit of the way our waste is managed by the company. Furtherwick Park SchoolA specialist College for the Media Arts Partners for Success : 4 Furtherwick Park SchoolA specialist College for the Media Arts Partners for Success The history of landfill started with high quality Hay being grown in the area, transported by barge to London for horse feed. Subsequently, and in order to clean up London’s manure and refuse, was brought back by barge to be spread and eventually buried. The 36 acre site has been in operation for over 100 years and will cease operation around 2017. Furtherwick Park SchoolA specialist College for the Media Arts Partners for Success : 5 Furtherwick Park SchoolA specialist College for the Media Arts Partners for Success The site receives around 2000 tonnes of household waste and also 9000 tonnes of commercial and industrial waste each week. The average ‘green’ waste is 500 tonnes (January this falls to around 200 tonnes). And ‘wood’ waste around 300 tonnes per week. Essex produces 750,000 tonnes of landfill waste annually Furtherwick Park SchoolA specialist College for the Media Arts Partners for Success : 6 Furtherwick Park SchoolA specialist College for the Media Arts Partners for Success The Green Waste composting helps produce a Soil Improver for household gardens and allotments which is available for purchase at Civic Amenity sites. It is turned for aeration daily and sprayed against odours and fire. Furtherwick Park SchoolA specialist College for the Media Arts Partners for Success : 7 Furtherwick Park SchoolA specialist College for the Media Arts Partners for Success The facility receives waste from local Councils and industry each weekday and from Recycling or Civic Amenity Centres all seven days of the week. The tipping face moves with the ‘supply’ daily and is also capped with restoration soil at the same time. Furtherwick Park SchoolA specialist College for the Media Arts Partners for Success : 8 Furtherwick Park SchoolA specialist College for the Media Arts Partners for Success The site imports an average of 4000 tonnes of restoration soil monthly including chalk and clay for ‘capping’ and profiling to the required contours. However, restoration material is carefully selected as to provided differing soils in order to encourage a divergence of animal, reptile, bird, flora and fauna populations. Furtherwick Park SchoolA specialist College for the Media Arts Partners for Success : 9 Furtherwick Park SchoolA specialist College for the Media Arts Partners for Success Overall, the company deals with some 750,000 tonnes of waste annually. The current cost per tonne going to landfill is £32 (€40). This will rise by £8 per year for the next 3 years. However, as part of the European directive on the Landfill Tax Trading Scheme (known as the LATS) will reduce the 750,000 tonnes by 80% by 2030. Furtherwick Park SchoolA specialist College for the Media Arts Partners for Success : 10 Furtherwick Park SchoolA specialist College for the Media Arts Partners for Success In addition to the cost per tonne going to landfill, other ‘penalties’ will be added if the license tonnage is exceeded. Liquid Industrial waste is no longer permitted at the site. The existing liquid waste, known as ‘Leachate’ undergoes many cleaning processes in order for it to be returned to the estuary. Furtherwick Park SchoolA specialist College for the Media Arts Partners for Success : 11 Furtherwick Park SchoolA specialist College for the Media Arts Partners for Success The Leachate treatment costs about 50 pence (€0.63) per cubic metre and the two lagoons hold around 70,000 and 140,000 Cubic metres collectively. Whilst birds use the two lakes, it does not sustain any life except for bacteria. Bales of old tyres (20 per bale) are used to create drainage channels and trenches and bank support. Furtherwick Park SchoolA specialist College for the Media Arts Partners for Success : 12 Furtherwick Park SchoolA specialist College for the Media Arts Partners for Success The company has developed the only demonstration ‘Aerox’ plant in the country, which accelerates bacterial decomposition of waste by oxygen treatment. Whilst it helps divert biodegradable waste from landfill by up to 40%, the Government have not financially supported this research. Furtherwick Park SchoolA specialist College for the Media Arts Partners for Success : 13 Furtherwick Park SchoolA specialist College for the Media Arts Partners for Success Methane is one of the ‘greenhouse’ gasses which is produced by the decomposition process. The site has a Methane Capture and Conversion capability. It has over 1000 ‘well heads’ on the site with many ‘manifold’ venting systems. Furtherwick Park SchoolA specialist College for the Media Arts Partners for Success : 14 Furtherwick Park SchoolA specialist College for the Media Arts Partners for Success The Methane is piped and vented from other gasses collected and fed into the converting engines. The company currently has seven engines which each produce over one mega watt. In 2009 this will increase to 9 engines producing around 11.6 megawatt of electricity. Furtherwick Park SchoolA specialist College for the Media Arts Partners for Success : 15 Furtherwick Park SchoolA specialist College for the Media Arts Partners for Success The electricity produced is ‘sold’ to the national grid. In ‘round number’ terms, each megawatt of electricity can supply one thousand homes with their power supply. Each manifold is checked for gas extraction data every two weeks. Furtherwick Park SchoolA specialist College for the Media Arts Partners for Success : 16 Furtherwick Park SchoolA specialist College for the Media Arts Partners for Success The site has planning permission agreements relating to final contours or landscape profiles. These profiles are updated to suit the periodic natural process which changes the designed contour by further decomposition and degradation. Furtherwick Park SchoolA specialist College for the Media Arts Partners for Success : 17 Furtherwick Park SchoolA specialist College for the Media Arts Partners for Success The Lower Wharf will start to receive restoration materials of up to 80,000 tonnes annually, by river of materials in the near future. Natural England have undertaken their own investigations at the site regarding the Black Tailed Godwit, a very rare bird. The SSSI Site has about 10% of the known world population of this bird. Furtherwick Park SchoolA specialist College for the Media Arts Partners for Success : 18 Furtherwick Park SchoolA specialist College for the Media Arts Partners for Success Each area used for tipping, firstly has a period of reptile translocation. Many species have been relocated including Grass Snakes, Adders and Newts. Twelve new habitats have been created and the area also sustains a very healthy Fox population. Furtherwick Park SchoolA specialist College for the Media Arts Partners for Success : 19 Furtherwick Park SchoolA specialist College for the Media Arts Partners for Success The creek is protected by East Haven Barrier and close by, Fobbing Horse Barrier. East Haven Barrier can be directly accessed from Northwick Road on Canvey Island and is the designated emergency services route. Furtherwick Park SchoolA specialist College for the Media Arts Partners for Success : 20 Furtherwick Park SchoolA specialist College for the Media Arts Partners for Success The future! In 2017 the site ceases to operate as a landfill site and will develop as a nature reserve. The existing offices are going to be handed over to the Royal Society for the Protection of Birds (RSPB) as an environmental and education centre
