This week we are discussing biosolids and human waste management
practices. As you are likely aware, biosolids can contribute large
quantities of nutrients to bodies of water and cause unintended effects.
Biosolids contain a decent quatity of phosphorous which is a limiting
agent for the growth of most plants. This makes the management of the
biosolids produced by cruise ships quite important. Biosolids from
cruise ships can cause large algal blooms that can disrupt the natural
ecosystem of the oceans in large areas. In this paper methods of
biosolids management are looked at from a risk assessment point of view.
I think that they have overlooked that they have a valuable resource at
hand that could be utilized for more before it's disposed of. I think
building a biodigester into the disposal cycle could yield a surprising
quantity of energy.
