In-Depth Information
Collection companies also realize how inefficient the collection system is
but obviously remain quiet as their business benefits by getting a share of
customers whether a large or small amount. This was evident when attempts
were made to contact each of the 20 companies to gather general information
about their collection strategies. Questions included but were not limited to: do
you use any route logistics when collecting solid waste, what is the size of
your solid waste hauler, and do you conduct 100 percent recycling? Many
were reluctant to answer questions as they feel any information provided will
lead to their demise. Few did provide insight into their operations. All
company names were kept confidential for this research.
While this system allows residents freedom to choose their solid waste
company, it testifies to an unawareness or denial of the high cost of the current
system, both environmentally and financially. First, several collection trucks
frequenting the same neighborhoods creates unnecessary and additional
vehicle emissions. This problem is exasperated by some companies using
more than one vehicle, one truck for solid waste collection and one for
recyclables. Thus, the number of collection trucks passing through a
neighborhood on collection days could potentially be greater than 20. This
process is even more inefficient when one considers that solid waste collection
companies are generally clueless about routing strategies. Under the best
circumstances they are driving a few blocks between stops. The average
distance between stops in single-collector systems is measured in feet, but is
usually measured in blocks in a system like Altoona's. Routes also include
trips to the transfer station once the trucks are filled. None of the companies
interviewed for this study have scientifically approached the issue and
systematically derived a route that minimizes mileage, intersection crossing,
and traffic congestion. It's been suggested that companies have little incentive
to invest time and money into route logistics. Rather, if a route is inefficient
resulting in higher gas costs, it is easier for the company to raise customer's
monthly bill.
Second, the increased truck traffic also generates noise pollution
throughout the day. Companies can begin collecting at 5AM and can continue
working until 6PM. Trucks themselves are loud but the noise is manifested
when workers use the hydraulic system to compact the solid waste. Although
they can collect until 6PM, most try and finish before the transfer stations
close at 3PM. Those that collect later in the day have no place to take their
solid waste and it remains in trucks overnight, sometimes parked in areas not
permitted. Being that some begin collecting at different times and locations,
trucks continually pass through neighborhoods during the day. Increased truck
