  4. 4. Updating your perceptions <ul><li>Materials recovery and recycling is high on the priority list of waste management strategies, certainly higher than incineration or land filling, which often meet public resistance. </li></ul><ul><li>The Keppel Seghers DANO Drum is ideally suited to precondition waste before final treatment. </li></ul>
  5. 5. Updating your perceptions <ul><li>It allows a maximum recovery of recyclable materials, an ideal pretreatment of the organic fraction prior to biological treatment and at the same time produces an excellent RDF type of fuel. </li></ul>
  6. 6. Updating your perceptions <ul><li>Waste is a heterogeneous mixture of different solid products such as paper, plastics, cardboard, metals, food waste, etc. The composition varies widely according to many parameters: </li></ul><ul><li>Origin (households, industry,…) </li></ul><ul><li>Region or country </li></ul><ul><li>Living standards and habits </li></ul><ul><li>Time of the year (winter, summer, rainy season) </li></ul><ul><li>Waste collection method (bags, open containers.) </li></ul><ul><li>Waste disposal becomes a top priority for many local governments. </li></ul>
  7. 7. Updating your perceptions <ul><li>In most countries the waste management strategy is a delicate mixture of ecological and economical interests and is based on the following principles, in decreasing order of priority: </li></ul><ul><li>1. Waste prevention </li></ul><ul><li>2. Recycling into usable materials </li></ul><ul><li>3. Composting </li></ul><ul><li>4. Landfilling </li></ul><ul><li>5. Energy recovery in Waste-to-Energy plants </li></ul>
  8. 8. What is waste? <ul><li>Technical : a product not longer wanted by its producer Note : it can still be a valuable raw material to others! </li></ul><ul><li>Economical : a product for which one has to pay to dispose of </li></ul><ul><li>Legal : “each matter or object of which the owner wants , plans or has to dispose of” </li></ul><ul><li>Different categories of “waste” according to source, physical & chemical composition, size, … </li></ul>

  12. 13. Seghers Dano Drum <ul><li>The core of a waste pre-treatment installation is the SEGHERS Dano Drum for waste conditioning . </li></ul><ul><li>The drum is a horizontally mounted, rotating steel cylinder which automatically shreds, mixes, conditions and sorts the refuse into components for either recycling, composting, or incineration with energy recovery. </li></ul>
  13. 14. SEGHERS DANO Drum By Keppel Seghers, Inc The Keppel Seghers DANO Drum Mark III has a length of about 79 ft and an internal diameter of 12.5 ft. An integrated screen is attached to the end of the drum.

  28. 29. <ul><li>Pulverization Increases the Bulk Density by 2-3. </li></ul><ul><ul><li>Savings of Transport Costs </li></ul></ul><ul><ul><li>Extending the Life Time of Landfills </li></ul></ul><ul><ul><li>Faster biological stability of Landfills </li></ul></ul><ul><ul><li>Separate fine fraction for landfill cover </li></ul></ul><ul><li>Faster Methane Production Compared to Crude Landfill </li></ul><ul><ul><li>Earlier Stabilization Period </li></ul></ul><ul><ul><li>Improved Commercial Exploitation </li></ul></ul>Bulk Reduction - Benefits
  29. 30. Principle & Process Implementation <ul><li>The rotation of the drum imparts a tumbling action to its contents, which leads to a breakdown of the softer components by particle collision and attrition as they repeatedly contact the drum wall and harder elements in the mixture. </li></ul>
  30. 31. Principle & Process Implementation <ul><li>The DANO system was originally designed as an aerobic composting system for municipal waste, either alone or in a co-composting process with sewage sludge. </li></ul>
  31. 32. Principle & Process Implementation <ul><li>This diagram shows the possibilities of mixing different wastes at the input of the Keppel Seghers DANO Drum system, as well as the different possibilities for the outlet streams: </li></ul>
  32. 33. <ul><li>Soil Improvement and Cover Material for Landfill </li></ul><ul><ul><li>No Need for Importing Cover Material </li></ul></ul><ul><ul><li>Immediate Saving </li></ul></ul><ul><ul><li>More hygiene and less vector attraction </li></ul></ul>Landfill waste pretreatment
  33. 34. <ul><li>Readily available RDF fluff and organic waste streams </li></ul><ul><li>Most of the metal fraction concentrated in DANO DRUM “metal rich” fraction </li></ul><ul><li>Fine material is fibrous and solid (not “pulped”) resulting in good handling properties </li></ul><ul><li>Simple, reliable system with low maintenance </li></ul>Materials Recovery - Benefits
  34. 35. <ul><li>attrition of paper and cardboard increases biogas production for anaerobic digestion </li></ul><ul><li>relatively low contamination of organic waste stream </li></ul><ul><li>increased digestion feed rate from same amount of Municipal Solid Waste with high-organic stream </li></ul><ul><li>good material handling properties (fibrous material) </li></ul><ul><li>reduced particle size and homogeneous </li></ul>Biological treatment - advantages
  35. 36. Protection and Reliability <ul><li>A number of triangular shaped projections are fitted in the Keppel Seghers DANO Drum to help prevent the formation of bundles of textiles. </li></ul>
  36. 37. Protection and Reliability <ul><li>In order to protect the drum from wear, Keppel Seghers DANO Drum uses a system which causes pulverized elements in the refuse to form a deep lining around the total internal periphery of the drum. This completely protects the cylinder shell and has proved to be extremely successful in ensuring, with minimum maintenance, a virtually everlasting life for the drum. </li></ul>
  37. 38. Unique and Different <ul><li>The flexible process implementation allows for a change in secondary resource markets and values. </li></ul><ul><li>It also copes with future policy changes due to public appreciation and the evolution of final treatment technologies. </li></ul><ul><li>This is not only a major advantage, it is also a necessity when considering the long lifetime of a Keppel Seghers DANO Drum. </li></ul>
  38. 39. <ul><li>Energy Recovery Out of pulverized MSW: </li></ul><ul><ul><li>More homogeneous than non-treated waste </li></ul></ul><ul><ul><li>Leading to higher efficiency and throughput, and better plant control </li></ul></ul><ul><li>Energy Recovery Out of RDF fraction </li></ul><ul><ul><li>High calorific value </li></ul></ul><ul><ul><li>More homogeneous than non-treated waste </li></ul></ul><ul><ul><li>Potentially better burnout </li></ul></ul>Feedstock for EfW Installations
  39. 40. <ul><li>Smoother Operation and More Stable Steam Flow </li></ul><ul><li>Easier Operation and Automation of the Plant </li></ul><ul><li>Automatic Feeding of the Waste is possible </li></ul><ul><li>Higher design throughput of waste </li></ul><ul><li>Higher Public Acceptance </li></ul>Feedstock for EfW Installations - Advantages
