Valuable Materials

6319e04/12VALUABLE MATERIALSrecovered from the raw material source wasteDomestic and industrial waste including biowasteare important raw materials and potential energysources. Numerous outputs can be recycled fromwaste. Most importantly, gas, electricity and heatcan be generated from various waste fractions.Turnkey and at one stop, KÜTTNER offers plantand equipment not only for solving disposal andrecycling problems but also for making waste treat-ment and processing an attractive field of businessfor customers, both economically and ecologically.Projects span waste reception through processingto the production of power and heat.As the physical and chemical properties of wastecan vary considerably, methods of waste treatmentmust be adapted to the individual task at hand. Toachieve this, KÜTTNER provides a wide range ofprocesses specially developed for mechanical,biological and thermal waste treatment.These processes can be combined to perfectlymatch the requirements of any specific task. Basedon very great experience of designing industrialplant and equipment, KÜTTNER engineers createtechnical solutions to exactly match their clients’individual needs.For our customers this means: one principal per-son of contact spearheading the KÜTTNERteam, with personal experience and in-depthknow-how; short decision-making processes andclear responsibilities.A globally acting group of companies hasdeveloped from the engineering company oncefounded in 1949 by Dr. Carl Küttner.Nowadays, their main focus is on building turn-key plants for the iron & steel producing indu-stry, foundry and NF (non-ferrous) industry,especially in the fields of process and smeltingtechnology, materials handling as well as ofenergy and environmental technologies.Küttner Energy & Environment is one of the lea-ding global players in developing and imple-menting innovative and sustainable energyand environmental technologies for efficientenergy use, reductions in environmentalimpacts and optimisiation of material cycles.Our scope of services comprises the designand engineering, construction, delivery, assem-bly, as well as the start-up and commissioningof the entire plant including control system anddata processing.Küttner systems can be found in almost allindustrial sectors. Worldwide Küttner-Grouppersonnel counts more than 650 employees,their owners themselves being active within thecompany.WASTE IS A PRECIOUSENERGY RESOURCEKÜTTNER ENERGY & ENVIRONMENT GMBHSubsidiary of Küttner GmbH & Co.

Theplant operates using the KOMPOGAS principle of “dry“digestion. Biogas arising from the digestion of the wasteis used in a co-generation plant for the production ofelectricity and heat. Digestate from the digester is dewa-tered and subjected to intensive enclosed aerobic bio-stabilisation (biodrying). Capacity of such plants is unli-mited due to the modular design.“Wet” Digestion PlantsESCHMALD is a Mesophilic Anaerobic Liquid Digestionsystem by Kuttner. Typical feedstocks are agriculturalbyproducts as well as food waste with a relatively highwater content. Technology consists of three units: thecombined mixing and hydrolysis tank (CMHT), the 1ststep digester which is the main digestion zone, and the2nd step digester where the final digestion process pro-ceeds. Again, capacity of these plants is unlimited dueto modular design.Biogas from foodwasteMechanical Pre-TreatmentMechanical waste treatment is used, on the onehand, for separating valuable reject materialsand, on the other hand, for conditioning thewaste for subsequent processing. In the scree-ning drum, the waste is separated prior todownstream processing steps into the:• fraction for material recycling,• fraction for energetic recycling,• fraction for thermal treatment,• fraction for biological treatment,and the residual fraction for disposal and subse-quent landfill. The resulting organic fraction< 60 mm is conveyed to the digestion plant.Biogas consists mainly of methane which can be used,for example, in co-generation plants for producing electri-city and heat. Alternatively, cleaned biogas can be usedas CNG fuel or fed into the natural-gas grid.KÜTTNER offers equipment for a wide range of processsteps, e.g. desulphurization, drying, booster and backupflare systems.CHP BiogasEngineCHP PlantRostockLaboratory trialson biogas yieldand qualityAutomatic craneKÜTTNER designs and supplies both “dry” and “wet” anaero-bic digestion plants. In these facilities microorganisms producean energy-rich biogas from organic waste. Digestate fromdomestic waste (MSW) is stabilized in a composting plant.When treating segregated biogeneous waste, the resultingdigestate can be composted and utilized as high-quality fertili-zer or growing-media.KÜTTNER supplies turnkey plants, spanning the complete pro-cessing route from waste reception through to biogas utilizati-on. KÜTTNER digestion plants comply with all disposal andlandfill regulations.Mechanical-biological waste treatment (MBT) ismaterial-specific waste treatment to generaterecyclate efficiently and where feasible with anenergy surplus. The waste to be treated is typi-cally from households and businesses. Our tech-nologies are matched to specific requirements ofa wide range of industrial and domestic wastes.Biogas-yield LaboratoryEnergy output from individual feedstock as well as bio-gas quality can be readily tested and calculated forclients to assess business options. Biogas yield and quali-ty depend on individual properties of substrates. The ser-vice-range comprises standard batch tests up to continu-ous pilot-scale digestion trials, analysis and a final report.Laboratory trials allow a proper basis for project deve-lopment and professional support of the project.Biogas UpgradingRaw biogas produced from digestion is roughly 60 %methane and this can be concentrated to over 98 %methane within an upgrading facility. This allows the injecti-on of upgraded biogas into the methane grid (natural gasgrid). Alternatively, upgraded biogas can be used locallyas compressed natural gas (CNG), e.g. as a vehicle fuel.Intermediate StorageKÜTTNER supplies unmanned crane systemswhich continuously feed waste material to thetreatment plant.
