WastetoEnergy game quiz
"The amount of municipal waste produced every day is still growing. Containing among others plastics and biomass, it is a source of energy. This is a quiz on turning waste to energy."

15 Points Per Correct Answer - No time limit  



1. In most countries around the world, municipal solid waste is put into landfills. In some countries, among others the Netherlands, Germany and recently the United Kingdom, land filling is prohibited or discouraged. Why?
    A landfill is a waste of energy
    To stimulate re-use of materials
    Landfills needs a lot of ground area
    All these reasons play a role


2. In the Netherlands in the seventies, the "ladder of Lansink" was developed. This is a list of ways to treat waste in order of preference. Which of the following orders is the order of the ladder of Lansink, keeping in mind that it starts with the most preferable waste handling method.
    combustion, prevention of waste production, recycling, landfill
    prevention of waste production, recycling, combustion, landfill
    prevention of waste production, combustion, recycling, landfill
    recycling, prevention of waste production, combustion, landfill


3. What is the most common way of generating energy from municipal solid waste?
    Incineration
    Composting
    Anaerobe digestion
    Gasification


4. Now, let's focus on the incineration of waste. If you look into an industrial waste incinerator in operation, what do you see?
    A cosy yellow fire, like in a fireplace
    Only degrading waste, the flames are colourless
    A blue fire, due to the high temperatures
    You cannot look into an incinerator, it is far too dangerous


5. Is the energy generated with the incineration of municipal solid waste considered renewable energy?
    Yes, since no fossil fuels are used.
    Around half of the energy produced is considered renewable, since around half of the waste is organic matter.
    No, plastics are combusted, which are after all fossil fuels.
    Yes, the waste needs to be handled anyway, the energy is free benefit.


6. Some environmental organisations have remarks on the environmental friendliness of waste-to-energy plants. What is considered a problem?
    During waste incineration, harmful substances are released.
    Waste incineration is just another form of fossil fuel combustion.
    No new landfill sites are made, this is a loss for the landscape.
    The flue gases from waste incinerators smell like rotten eggs.


7. What substance is typically formed during the incineration of waste, along with compounds like CO2, SOx, NOx and HCL?
    Methane
    Dioxins
    Noble gasses
    Radioactive matter


8. What is an important difference between electricity producing waste-to-energy plants and power plants?
    Even if no electricity can be supplied to the public grid, the plant stays in operation.
    The electricity production of a waste-to-energy unit is much higher.
    Liquid ashes are formed in waste-to-energy plants.
    Waste-to-energy plants have batch operation, instead of continuous operation.


9. The efficiency of a waste-to-energy plant is 20 - 30 %. Efficiency = produced useful energy divided by energy in fuel. What methods are used to increase the efficiency of waste-to-energy plants?
    Supplying heat for district heating.
    All of these methods increase the efficiency.
    Using a water cooled condenser instead of an air cooled condenser.
    Non of these methods increase the efficiency.


10. The incineration of waste produces flue gases and ashes. The flue gases are cleaned and exhausted to the atmosphere. What is done with the ashes and flue gas cleaning residues?
    All ashes and residues are used in livestock feed.
    All ashes and residues are put in landfill.
    A large part of the ashes and residues is used in construction works.
    A large part of the ashes and residues is pulverized and used as sand on the beach.
