Waste management
The definition waste management
What is the processes and actions required to manage waste from its inception to its final disposal.
The definition of environmental stewardship
What is the use and protection of natural environments in responsible ways. This includes conservation and sustainable practices.
The leading source of energy in the US
What is coal
The definition of renewable energy
What is energy derived from natural sources that are replenished at a higher rate than they are consumed.
The definition of bioremediation
What is the use of either naturally occurring or deliberately introduced microorganisms or other forms of life to consume and break down environmental pollutants, in order to clean up a polluted site.
The 3 R's of waste management
What is reduce, reuse, and recycle
Examples of environmental stewardship
What is installation of water saving fixtures, grey water recycling systems, reuse of production waste water, rain water harvesting systems
Examples of non-renewable energy sources
What is fossil fuels: coal, petroleum, and natural gas.
Generating renewable energy creates far lower ___ than burning fossil fuels.
Three categories of bioremediation techniques
What is in situ land treatment for soil and groundwater; biofiltration of the air; and bioreactors, predominantly involved in water treatment.
5 types of waste management
What is landfill, incineration, waste compaction, composting, vermicomposting.
Roles of environmental stewards
What is doers, donors, and practitioners.
The main element in fossil fuels
What is carbon
Sources of renewable energy
What is solar energy, wind energy, geothermal energy, hydropower, and ocean energy
The definition of bioventing
What is "This process involves drilling small-diameter wells into the soil that allows air ingress and passive ventilation where ground gases produced by microbial action are released. This approach can be used for both soil and groundwater problems, as it lets oxygen and nutrient rates be controlled by adjusting the vent rate."
Importance of waste management
What is protect the environment and also save on costs or reduce expenses for disposal
Characterisitcs of environmental stewardship
What is social equity, community benefit, economic impact, and environmental protection.
The definition of carbonization
What is the process that ancient organisms undergo to become coal.
What is "Ocean energy derives from technologies that use the kinetic and thermal energy of seawater - waves or currents for instance - to produce electricity or heat."
The definition of biosparging
What is biosparging "involves high-pressure air injection forced into the soil or under the groundwater table. This process increases oxygen concentration and enhances biological Air sparging is highly effective and affordable, compared to excavating and tilling contaminated soil or circulating polluted water through pumps and filter tanks."
The definition of vermicomposting
What is the use of earthworms to convert organic waste into fertilizer.
Purpose of environmental stewardship
What is to protect the resilience of crucial ecological processes, including those of flora, fauna, and atmosphere.
The definition of peacock coal
What is a black-ish sedimentary rock that can be burned for fuel and used to generate electricity. Coal is the leading source of energy in the United States.
The largest source of renewable energy in the electricity sector.
The definition of bioaugmentation
What is "Bioaugmentation is often used to add extra indigenous microbes or to implant exogenous species to the site. Augmentation works in conjunction with both bioventing and biosparging applications, but has limitations. Non-indigenous microbes are not usually compatible with indigenous bacteria, so much of the bioaugmentation additives are additional microbes to those already at work."
