- A city generates on average 1000 metric tonnes/day (t/d) of municipal solid waste and follows an integrated waste management system. 15% of the total waste is recycled, 40% used to produce compost, 25% converted to refuse derived fuel (RDF) with 80% efficiency, and the remaining disposed in a sanitary landfill. The calorific value of the RDF is 15 MJ/kg. The electrical energy that could be generated from the RDF with a thermal-to-electrical conversion efficiency of 20% is ____________________ (in MWh/d, rounded off to two decimal places).

An industry with an effective stack height of 80 m emits 1200 g/h of CO. The windrose indicates wind speed $u=3$ m/s. At a downwind distance of 2 km (plume centerline), the dispersion coefficients $(\sigma_y,\sigma_z)$ depend on wind direction as per the table below.
Air Pollution Concentration Calculation
During the maximum duration of the year (i.e., the most frequent wind direction from the windrose), the ground-level PM2.5 concentration is to be computed at the plume centerline at 2 km. Find the concentration (in μg/m3, rounded off to two decimal places).
Dispersion Coefficients (in m)
Wind Direction Dispersion Coefficients (in m) Northeast Crosswind: 50, Vertical: 20 North Crosswind: 45, Vertical: 30 Northwest Crosswind: 40, Vertical: 35 East Crosswind: 45, Vertical: 30 Southeast Crosswind: 55, Vertical: 35 South Crosswind: 60, Vertical: 40 Southwest Crosswind: 65, Vertical: 45 West Crosswind: 70, Vertical: 50 Table 1: Dispersion coefficients based on wind direction
