Low-Resolution Version of the Christiaens Bulltin 4 Brochure

Organic waste products are easily degraded by a diverserange of micro organisms. However, when this processtakes place inside a ‘closed box’ it is possible to controlall parameters involved in this process.With the know-ledge derived from the mushroom industry theChristiaens Group developed an in-vessel compostingsystem for all kinds of waste. The specially designedChristiaens Control system is able to control a variety ofimportant parameters such as temperature, oxygen leveland air pressure. By means of fan speed and damper con-trol it is possible to improve the in-vessel conditions.When the ‘Christiaens Controller’ is properly set, thecomposting system starts with the decomposition ofeasily degradable organic matter. During this process alarge amount of heat is generated. Due to this heatrelease the temperature in the material can rise to over70ºC. Under these conditions large quantities of waterare evaporated.Besides optimising the in-vessel composting system theChristiaens Group also had eye for further mechanisa-tion of the total composting plant. In 1992 theChristiaens Group for the first time patented an auto-matic system for filling and empting of the compostingtunnels.bulletinchristiaens groupb u l l e t i nc h r i s t i a e n s g r o u pwe make yourwaste valuable4index:- Hamilton centralized compost facility page 2- Nangong composting plant page 3- RAB page 3- Linde page 4- Banff,Alberta, Canada page 6- Prince Albert SaskatchewanCanada page 6 - AZB Hanover, Germany page 7 - Group owned test facility page 7 Opmaak_afval.qxd 01-12-2008 09:55 Pagina 1Maple Reinders, along with key project partners Associated Engineering,Aim Waste Management and The Christiaens Group of the Netherlands,has undertaken a benchmark Design/Build/Operate project to create anew centralized compost facility for the City of Hamilton. The 115,000square foot in-vessel composting facility will process 60,000 tonnes of res-idential curb-side wet waste into a rich, organic soil material - in the Cityof Hamilton’s terms - “Black Gold. The new compost facility will help theCity achieve its mandate to divert its current solid waste stream by 65%by the year 2008. The Hamilton composting process resembles typicalbackyard composting, but is accelerated using science and automation:Collection: Organic waste is collected in a “green cart” at the curb, andtransported to the new facility, where it is unloaded, shredded and con-veyed to an empty compost tunnel through roof openings.An automatedfilling cassette travels the length of the tunnel to ensure even distribution.Phase 1 Composting: Once the tunnel is filled, the ageing process com-mences. Foul air is recycled, and only a small amount is exhausted througha large organic biofilter. After 7-10 days, the tunnel is emptied and thePhase 2 tunnels are filled.Phase 2 Composting: Phase 2 tunnels allow the compost to mature foran additional 7-10 days. Once complete, loaders remove the compostfrom the tunnel to be screened for all unacceptable materials, and refinedto a specific marketable size. After screening, the compost is conveyed toan outdoor covered curing area.Final Product: After curing, the compost is shipped to outlying markets,such as local nursery operations, for potting soils. The environmental ben-efits of such a bold composting program are self-evident, but extra valuewill be realized by turning waste into a marketable, profitable endproduct.hamilton centralizedcompost facilityUNDER CONSTRUCTIONLocal dignitaries lead agroundbreaking ceremony for the new compost plant.christiaens group I projects I page 2Opmaak_afval.qxd 01-12-2008 09:55 Pagina 2page 3RAB is an Austrian engineering agency specialized in providing advice andguidance to local authorities and companies on setting up waste com-posting installations.The designs are made according to a pre- determinedconcept. Part of the concept is the supply of pre-sorted waste to the tun-nels and filling the tunnels.rabThe entire project comprised 2 reception and sorting plants in the cityand one large composting plant where organic waste from the 2 sortingunits is processed into compost.nangong compostingplantProject CountryASA Halbenrein AustriaSt Pölten AustriaPalm Meadows USALahti FinlandNANGONG COMPOSTING PLANTHOURSEMANURE COMPOSTING PLANT PALM MEADOWS FLORIDAComposting capacity: 120,000 tons / year Number of tunnels: 30 Process: 2+3+3+10 weeks Usable compost after 7 weeks: 39,000 tons / year.Christiaens Machines B.V. has been an established name in the world ofwaste treatment for many years.

Constructing waste composting tunnels,combined if requested with methanization plants, is their specialty. Since2000 Linde KCA has used automatic tunnel filing/emptying machines fromChristiaens Machines and automatic tunnel doors supplied by ChristiaensConstruction.Control systems are supplied by Christiaens Controls.Christiaens Group and Linde KCA recently entered a partnership. In thefuture, both partners will be closely collaborating on offering and con-structing waste composting projects throughout Europe.MEAB BERLIN PROJECTCOMPOSTTUNNEL LINZ AUSTRIAOpmaak_afval.qxd 01-12-2008 09:55 Pagina 4page 5PROJECT VILLENA SPAINEGW KREIS BORKENPROJECT COUNTRY NUMBER OF CAPACITY YEAR OF TUNNELS TONS/YEAR COMPLETIONEGW Kreis Borken Germany 26 2000Ecoparc Barelona Spain 29 2002Villena Spain 16 2003EGW Kreis Borken Germany - 2004Stadt Linz Austria 16 2004Leipzig / Cröbern Germany 44 2005Berlin / Schöneiche Germany 30 2005Cap Lorient France 22 2005Lille France 22 2006Erfurt Germany 12 2006Fridhaff Luxemburg 18 200685.000 ton300.000 ton40.000 ton115.000 ton85.000 ton300.000 ton180.000 ton55.000 ton110.000 ton90.000 ton37.500 ton..BERLIN / SCHONEICHEOpmaak_afval.qxd 01-12-2008 09:55 Pagina 5christiaens group I projects I page 6The Town of Banff decided to expand and upgrade their existingWastewater Treatment Plant (WWTP), through the use of theDesign/Build/Operate (DBO) project delivery model. The DBO projectdelivery model presented a unique opportunity for the Town of Banff totruly find the most efficient process to meet its needs. In order to be suc-cessful the proponent needed to select the most effective design based onboth the capital as well as the long-term operational costs.The DBO teamincluded Earth Tech (Canada), Maple Reinders (Canada) and ChristiaensGroup (NL). The tunnel composting system utilizes aerated static piletechnology, and is based on a process-control system developed by theChristiaens Group.The control system allows a high level of control overall phases of the composting system and requires little operator attentionover the 21-day composting cycle.banff, alberta, canadaThe Prince Albert composting facility, is designed by Earth Tech (Canada)and the Christiaens Group (NL) in order to treat sewage sludge.The facil-ity is operated by the city of Prince Albert. Much effort is put in to thedesign of the aeration system. At the end of the aeration system an ammonia scrubber and biofilter are incorporated. Woodchips are mixedthrough the sludge to improve the ’compostability’. This mixing is doneinside the building due to the extreme temperatures which can bereached outside (-40ºC).prince albert,saskatchewan, canadaOpmaak_afval.qxd 01-12-2008 09:55 Pagina 6page 7For development of new composting systems and for optimising theprocesses, the Christiaens Group has its own testing facility.This facilityconsists out of two small, lab scale, containers (±2m3) and one big con-tainer (±40m3).group owned test facilityaha hanover, germanySTARTING UPIn this facility, 120.000 t/a of MSW is collected and separated. The small,organic fraction will be treated anaerobically in order to derive methane gas.The residue which comes out of the anaerobic digesters is going into theChristiaens Composting Tunnel system, these tunnels will aerobically treatthis material. Special feature in this plant is the automatic emptying system;the material is taken out of the tunnels by means of the patented ChristFloor system.This plant is designed in a environmentally and sustainable way in closecooperation with Weser Engineering (Germany).Opmaak_afval.qxd 01-12-2008 09:55 Pagina 7Christiaens GroupWitveldweg 104 - 106 -1085961 ND Horst - The Netherlandsinfo@christiaensgroup.comwww.christiaensgroup.comtel. +31 (0)77 399 95 00t h e p o w e r o f c o m b i n e d e x p e r i e n c e© ArtLine | KesselCGB40605SEWAGE SLUDGECanada Banff WWTP Banff,AlbertaCity of Prince Albert Prince Albert,SaskatchewanRegional Municipalityof Wood Buffalo Fort McMurray,AlbertaSpain GTR BarcelonaGTR BlanesThe Netherlands GMB TielGMB ZutphenUK Anglian Water IpswichUSA BFI UnityBIOWASTEBelgium DDS-Verko DendermondeCanada City of Hamilton HamiltonRegion of Peel TorontoGermany Schneider GießenEmsland MeppenWGV QuarzbichlWKG WürzbergThe Netherlands Kaathoven BladelKaathoven St. OedenrodeOgar Oude PekelaRAZOB AchtRAZOB DeurneUK Viridor WasteManagement Ltd.
