I think that this 11 pages pdf file (from an Australian university) can help a lot in waste management in sciences' laboratories:

Simulate your science exercises online whenever possible using a virtual lab: https://www.youtube.com/watch?v=O55o0wimf_w

1. Demonstrate the practical while projecting a video to the whole class to be seen.

2. Grouping students to do a single practical.

3. Select what practicals can actually support to get the Intended learning outcome and avoid doing unnecessary practicals.

4. Upload a video of the practical to Learning Management System to give an initial preparation to students which can reduce material usage during actual practical.

5. Collect answers online through the Learning Management System (Paper Saving)

6. Deliver teaching materials using only electronic methods. LMS (Paper Saving)

7. Record the practical once you do it , next year you can show it without attending and you can save the time.

8. Ask students to purchase simple things and bring - it will motivate them to interact with real environment and learn while reducing university purchase bills.

Choosing lab activities that will not harm the environment. Find ways of neutralising unwanted chemicals

This is a very interesting and crucial question. All answers are also very well-stated.

I think it all comes to implementing appropriate planning and management of resources. This includes many things as:

1) Knowing (and showing) what to use. Neither less nor more.

2) Demonstrating to learners how to use the materials.

3) Emphasizing on reducing waste!

The necessary managerial skills have to be developed for educators and learners.

Simulation strategies

Hi, there are many methods of teaching to reduce waste of materials in the Laboratory. You can use group learning method, demonstration, use of real life examples, discovery methods, simulation methods.
