A small community generates 100,000 lb of MSW, and sends waste to be recycled, incinerated, and landfilled. Anything not sent to recycling, incineration, or composting facilities is landfilled. The information associated with this system is shown in the table below. Constituent Recycling Efficiency (% of generated) Composting Efficiency (% of generated) Incineration Efficiency % of generated) Food Paper Cardboard Yard Waste Rubber Plastic Metal % Composition of Generated Waste 11.6 26.2 13.3 21 5.7 5.6 6.1 0 30 5 0 0 20 35 55 10 5 40 0 0 0 5 30 20 0 20 30 2 It is important to note that there are only two waste collections from the homes in this community: (1) Recyclables only, sent directly to the recycling facility and (2) Mixed waste (minus recyclables), which is sent to a sorting facility. All waste at this facility is sorted and then sent to either the landfill, compost facility, or incineration facility. Information about each facility: At the sorting facility: All materials are sorted properly and correctly with 100% efficiency. At the recycling facility: 90% of the waste is recycled and 10% is ultimately sent to the landfill. Assume these percentages apply for all wastes sent to the recycling facility. At the composting facility: 100% of the waste is composted. At the incineration facility: 95% of each material is incinerated. The remaining 5% of each is sent to the landfill as ash. Complete a MFA, with a drawing, that illustrates how the mass of each waste material is managed.
