THE WASTE INDUSTRY IS MASSIVE AND THE SUBJECT VAST.
To understand better what is being wasted a new pair of eyes is needed in ANY environment.
Why? It is a know fact that when visiting new premises, business or home you pick up all the areas where things are wasted, dangerous, and so on. The next time you visit you only pick up half of the original items/situations you noticed and on the third visit everything is taken as being normal. It follows, if it is your own area you work or live in, you do not see these areas/situations. Familiarity breads contempt/complacency.
Having said that you cannot avoid some waste, be it from the processes used in a business, accidents, bad luck, bad decisions, changed market conditions outside your control etc. What you can and should do is have strict discipline when dealing with any form of waste. Remember waste was originally a product or resource that cost time, which in itself is a cost, and money to acquire.
Physical waste in its many forms can be recycled. This is where discipline and information are essential, be it segregation, compaction, or cost of transportation. Is it toxic or dangerous, is there a market for your waste, how far away is the processing plant/area? These are are all areas to be monitored on a regular and ongoing basis. Many businesses do not have space to store physical waste and makes reducing it in the first place a priority. Skips can be a great source of revenue for waste companies because they know that in the majority of cases the main element is fresh air. Staff are not trained what to put in, what to leave out and to maximise the space.
