  1. The French standard MODECOM Description of the method Weighing the sample Opening all the bags on the sieve of 100 mm Sieving at 100 mm Manual sorting of the > 100 mm ( 250 kg ) Sieving at 20 mm Manual sorting of 1/8 of the 20 to 100 mm (12kg) Sieving at 8 mm Weighing the categories Drying sub-samples Calculating the results UR GERE - B. MORVAN - AWAST 28/06/01

  2. The French standard MODECOM The method is good for The sieves of 100, 20 and 8 mm The categories and sub-categories The method is bad for The manual sorting Work on wet matter Sanitary conditions The granulometry with fix plan sieves Work on wet matter The result is dependent on the operator UR GERE - B. MORVAN - AWAST 28/06/01

  3. MSW sorting on dry matter Weighing the sample Opening all the bags on the floor Manual sorting : motley, bottles of glass, aerosols Weighing about 20 kg, drying Sampling 120 kg (a quarter) Weighing the sample (120 kg) to dry Weighing the rest (360 kg) to reject Drying at 70 °C Motleys and glass without aerosols The quarter UR GERE - B. MORVAN - AWAST 28/06/01

  4. MSW sorting on dry matter(continuation of the method) Sieving the quarter with a closed trommel at 100, 20 and 8 mm Manual sorting All the > 100 mm ( 50 kg ) 5 kg of the 20-100 mm 500 g of the 8-20 mm Ignition loss on the < 8 mm Calculating the results UR GERE - B. MORVAN - AWAST 28/06/01

  5. MSW sorting on dry matter The method is good for The sieves of 100, 20 and 8 mm The categories and sub-categories The manual sorting Work on dry matter Sanitary conditions The granulometry with a trommel Work on dry matter The result is not dependent on the operator Inconvenient Opening the bags on the floor Necessity of a trommel UR GERE - B. MORVAN - AWAST 28/06/01

  6. MSW of Lisbonne Dry matter : 53,9 % UR GERE - B. MORVAN - AWAST 28/06/01

  7. MSW sorting on dry matter Comparison of some results UR GERE - B. MORVAN - AWAST 28/06/01

  8. MSW sorting on dry matter The accuracy of the method OM NSOM absolute error % 0,97 1,26 relative error % 1,41 2,62 UR GERE - B. MORVAN - AWAST 28/06/01

  9. For AWAST, is it necessary to sort waste ? It will be dependent on what we search and the accuracy we’ll need We have mainly 4 kinds of waste : Selective collection MSW Biowaste Green or yard waste We have mainly 4 kinds of plant Sorting plant Composting plant (aerobic and sometimes anaerobic) Incineration plant Landfill UR GERE - B. MORVAN - AWAST 28/06/01
