My example for put items for other purposes was to use water used for cooking rice to be used for watering plants. This is in a way killing two birds with one stone. By doing this we will be recycling at the same time also putting the water used for cooking rice to other uses.

My example for eliminate was to change a normal bottle into a squirt bottle.If you took a 1.5 litre bottle and changed the material to rubber and eliminate some parts of the bottle according to the picture, you will get a very good squirt bottle.
