Step Activity
 Part of the organic fraction of the sample should be then oven dried at
1000C for 24 hours, pulverized, passed through 0.22 mm pore size
Step - sieve, and mixed thoroughly.
VII  This powder should be subjected to detailed chemical analysis such
as, moisture Content, volatile solids, ash, calorific value, carbon,
hydrogen, nitrogen, sulfur, phosphorus, potash, C/N ratio.

Figure 3-3: Quartering Method of Solid Waste Sample Analysis

3.5.2 QUALITATIVE ASSESSMENT
The qualitative analysis of the solid waste sample mainly divided into physical and
chemical parameters.
Physical Characterization of waste:

The physical characterization consists of the physical analysis and particle size
analysis. The parameters to be covered under the physical characterization are as
mentioned in Table 3-4 and Table 3-5.

Particle size characterization should be done with screen sieve size 200mm, 100mm,
75mm, 35mm, 16mm and 4mm respectively.
