A waste to energy plant burns dry solid waste of composition: Carbon = 35%, Oxygen = 26%, Hydrogen = 10%, Sulphur = 6%, Nitrogen = 3% and Inerts = 20%. Burning rate is 1000 tonnes/d. Oxygen in air by weight is 23%. Assume complete conversion of Carbon to CO2, Hydrogen to H2O, Sulphur to SO2 and Nitrogen to NO2.
Given Atomic weights: H = 1, C = 12, N = 14, O = 16, S = 32
The stoichiometric (theoretical) amount of air (in tonnes/d, round off to the nearest integer) required for complete burning of this waste, is __________.
In a solid waste handling facility, the moisture contents (MC) of food waste, paper waste, and glass waste were found to be MCF, MCP, and MCG, respectively. Similarly, the energy contents (EC) of plastic waste, food waste, and glass waste were found to be ECPP, ECF, and ECG, respectively. Which of the following statement(s) is/are correct?
To design an optimum municipal solid waste collection route, which of the following is/are NOT desired:
The following table gives various components of Municipal Solid Waste (MSW) and a list of treatment/separation techniques.
| Component of MSW | Treatment/separation technique |
|---|---|
| P - Ferrous metals | i - Incineration |
| Q - Aluminum and copper | ii - Rapid composting |
| R - Food waste | iii - Eddy current separator |
| S - Cardboard | iv - Magnetic separator |

Identify the treatment technology/technologies NOT recommended for highly biodegradable organic solid wastes.
