From The Centre for Industry Education Collaboration (CIEC), these resources allow students to consider the problems of industrial waste disposal. In particular they focus on the biological treatment of industrial waste using air as a source of oxygen and problems that such biological treatment plants face.
Aimed at students aged 12-14 years, the activities look at:
* The role of chemical reactions in producing useful materials
* The waste produced when carbon dioxide is produced in the laboratory
* Different types of industrial waste disposal
* Degradability of waste, requirements for biodegradation and rate control
* The important components of an industrial biological waste treatment plant
* Whether the use of pure oxygen to biodegrade waste is more efficient than using air alone.
Finally, students are given a problem to solve in which a company has decided to change its treatment system to meet new regulations.
The materials contain full teacher guidance, student notes and activity sheets.
