Using the waste data given in the Table below and with the information on local conditions

as outlined below, estimate the total weekly mass $($tonnes$)$ and volume $($m$3)$ of waste typically generated by

a community of the size of the City of ABC $(120000$ population$).$ Exclude industrial waste as it is handled

and disposed of by the industries themselves. Account for hazardous waste separately. Assume the

following:

Residential and commercial wastes are co$-$collected by the municipal collection system, with the recyclables

collected in a separate stream

Institutional wastes are collected separately and disposed of at the transfer station

Construction and demolition waste collected separately and disposed of at transfer station

Hazardous waste separation is encouraged with a free drop off site managed by the City

Special wastes are accepted at the transfer station

Due to composting, municipal service wastes disposed of directly at transfer station, not incorporated into

total mass

Assume the following uncompacted waste densities for waste stream described above:

Residential and Commercial

Paper and cardboard @$40\%$: $70$ kg$/$m$3$

Glass @ $7\%$: $200$ kg$/$m$3$

Metal @ $2\%$: $160$ kg$/$ m$3$

Plastic @ $6\%$: $60$ kg$/$m$3$

Rest: $250$ kg$/$m$3$

Special: $185$ kg$/$m$3$

Institutional: $220$ kg$/$m$3$

Construction and demolition: $1200$ kg$/$m$3$

Street cleaning: $600$ kg$/$m$3$

Parks: $300$ kg$/$m$3$

Catch basins: $1100$ kg$/$m$3$

Sludge: $1050$ kg$/$m$3$

HW: $1000$ kg$/$m$3($assume mostly liquid$)$

How many garbage truck trips are made each week to the transfer station for the

residential and commercial waste? Recyclables and rest are handled in separate

vehicles. Assume a typical compactor has a volume of $15$ m$3$ at a density of $300$
