Green Chemistry

Sustainability is:-

Development which meets the needs of people today without worrying how future generations can meet their needs.

The raw material for making synthetic ethanol

is:-a.crude oilb.municipal wastec.plant sugarsd.sugar cane

Which is the most sustainable method of

dealing with waste in your “wheelie bin”?

a. incinerate or burnb. landfillc. recycled. reduce the amount of waste

The advantage of making ethanol by the synthetic route

is:- a. the purification process is

expensiveb. there is 100% atom economyc. the raw material is a fossil fueld. toxic benzene is needed in the

drying process

Which are the best examples of reducing

waste? a. dumping waste into landfillb. burning waste gas without

using the energyc. recycling polymer based

carpetsd. using PET bottle to make

fibres

From what do we get feedstocks?

What are the three main uses of

ethanol?

Put these stages in the correct order to sumarise a

chemical process.

Why do biocatalysts lower the energy

demand for a chemical process?

Why is a process which contains fewer separation

and purification processes greener?

What is the disadvantage of

closed loop recycling?

Extraction of iron and carbon by a blast

furnace cleaning system is a “sustainable change”. How?
