One thing that annoys me is we seem to be in a downward spiral, with companies making new or 'improved' products in attempt to make us consume more. The more we consume, the more these same companies produce and the more turnover they have.
This is example and how we have found a solution:
Over the past decade or so we have noticed that the viscosity and nozzles of dishwashing liquids have changed. Years ago we used to buy the concentrate varieties and these were thick liquids in containers with comparatively small hole nozzles. It took some effort to squeeze liquid from the bottles and the bottles as a result tended to last months before needing to be replaced.
Today, most concentrated dishwashing liquids are a lot runnier (less viscous) and the the nozzles on the bottles have larger openings allowing higher volume to be more easily squirted from the bottle. Our solution was to take a pump off another container (a sorbolene cream pump pack) which had the same standard cap thread, cut the pick up tube to length and then attach it to the top of the dishwashing liquid bottle.
The result is:
We now have a pump pack which allows us to meter out the amount of dishwashing liquid we need. One pump is usually enough to wash up all our dishes, but if we are having foods which may have a higher fat content, we may need to empty the sink and refill to complete a wash. Before the change, a 450mL bottle would last about 3-4 weeks (3 washing events per day). Now we get at least 6 weeks from the same sized bottle. In effect we have reduced our use by about 50% without affecting the washing up results.
DO YOU HAVE ANY EXAMPLES WHICH OTHERS MAY BE INTERESTED IN TRYING?
