The lecturer argues that problems associated with single-stream recycling are not serious. This sharply contrasts with the reading passage's claim that this method has many shortcomings.
To begin with, the lecturer contends that single-stream recycling is not dangerous as being said. To be specific, since it is not difficult to use carts, if people are well-educated how to use carts, it is unlikely that they cause traffic hazards or leave materials such as bottles on the street. This rebuffs the reading passage's assertion that the single-stream system is perilous.
On the top of that, the lecturer insists that the amount of recycled materials increases by single-stream recycling. This is because, people are more willing to recycle materials when they can just recycle materials without the process of sorting. To be specific, though there can be one percent loss of gathered materials through this way because of contaminating problem, there should be fifteen percent increase in the amount of recycling materials when people can make use of this method. Thus the latter exceeds the former entirely. This contradicts the reading passage's claim that single-stream method has an effect on decreasing the amount of available recycling materials.
Lastly, the lecturer maintains that the single-stream recycling is cost-effective. To be specific, even though there is additional cost in sorting process, the cost for collecting materials decreases far more. Thus, overall cost is smaller than the traditional recycling program. This reputes the reading passage's argument that single-stream recycling is more costly than the old method. |
