Q: Biorenewable resources have only one feedstock source, dedicated energy crops.
- True
- False
A: False

Q: Industrial ecology is defined as "process outputs."
- True
- False
A: False

Q: Dedicated energy crops are burned in power plants to generate electricity or hydrolyzed to release fermentable sugars for distillation into transportation fuels.
- True
- False
A: True

Q: Examples of agricultural residue, or waste, are:
- Bagasse
- Corn stover
- Rice hulls
- All of the above
A: All of the above

Q: As a waste material, yard waste is the same season-to-season and makes an excellent feedstock.
- True
- False
A: False

Q: Municipal solid waste has an average makeup of: 50% paper, 20% plastics and other fossil fuel products, 10% food, and 20% glass and metal.
- True
- False
A: True

Q: Cereal manufacturers and breweries generate waste that may be watery or dry and can be converted to energy.
- True
- False
A: True

Q: Manure and sewage harnesses a chemical energy that is converted to electric power and can be captured from municipalities and livestock.
- True
- False
A: True

Q: Seed corn that cannot be guaranteed to germinate is not sold for planting or animal feed. It cannot be landfilled due to fungicides, therefore it can be sold to burn in boilers.
- True
- False
A: True

Q: Dedicated energy crops have only one "energy-rich component": lignocellulose.
- True
- False
A: False

Q: Lignocellulose is humanly digestible.
- True
- False
A: False

Q: Thick-stemmed grasses are not labor intensive to harvest.
- True
- False
A: False

Q: Herbaceous crops resemble hardwoods and their low lignin content improves accessibility to carbohydrates.
- True
- False
A: True

Q: Understanding plant components determines the biological processes needed to convert biomass into transportation fuels and chemicals.
- True
- False
A: True

Q: Which of the following compositional components are analyzed for biomass conversion to transportation fuel? (Check all correct responses)
- Plant composition
- Heating value
- Production yields
- Bulk density
A: Plant composition; Heating value; Production yields; Bulk density

Q: The length of a plant's fiber is important in determining how much processing is necessary to convert it to fuel.
- True
- False
A: True

Q: It is easy to estimate accurate ethanol yields from any dedicated energy crop.
- True
- False
A: False

Q: Energy consumption is measured in quads, or 1 million BTUs.
- True
- False
A: False

Q: In terms of generating fuels and chemicals, a kilogram of cellulose is equal to a kilogram of hydrocarbons found in petroleum.
- True
- False
A: False
