e2.5 investigate a local, regional, national, or global waste management practice (e.g., local practices such as recycling or charging for residential and/or commercial garbage bags; shipping garbage to landfill sites in another region; disposal of nuclear waste; dumping raw sewage into rivers, lakes, oceans), and communicate their findings [PR, C]
E. Understanding Basic Concepts
By the end of this course, students will:
e3.1 describedifferentcategoriesofwaste(e.g.,bio- degradable, recyclable, toxic, organic, inorganic)
e3.2 explain some current waste remediation practices used with substances or products that are not environmentally friendly (e.g.,
“Toxic Taxi” for pick-up of household hazard- ous waste; the recycling of plastic to make furniture and “lumber”)
e3.3 describe the scientific principles involved in processing solid, liquid, and gaseous waste (e.g., combustion, decomposition, pyrolysis)
e3.4 explain common strategies and technologies used in the collection and storage of waste (e.g., strategies such as recycling, composting, dumping in landfill sites; technologies such as compacters, enzyme digesters, flocculation tanks)
e3.5 explain how scientific knowledge and technological processes have been applied in the development of environmentally sound waste management strategies (e.g., accelerated waste aeration, bioremediation)
