Alot of the course content looks like what i did 15 years ago. The landfill part should be taken out as the future is recycling, waste to energy and the like. I work for a private waste company (have done for the last 9 years) and we are looking at composting, waste to ethanol, washing plants. The waste industry is a huge growth industry and will be for the next few years while we play catch up with the rest of Europe. Its also where people are wanting to invest money.
Other units will give a good grounding in alot of areas but she may still need more specific training when she has a job. I have just done my NEBOSH health and safety to give me another area to look into.
Best of luck to her, she just needs to look into what area of tree hugging she wants to get into!!
