|Avoid or minimise the use of hazardous, toxic or in any other way environmentally unfriendly materials.
||Decrease amount of harmful gaseous, liquid or solid emissions during production
|Minimise and recycle residues and waste from production processes, within the manufacturing plant or outside it
||Decrease amount of raw material required and the amount of waste created by production processes
|Minimise use of energy-intensive process steps, such as high heating differentials, heavy motors and extensive cooling
||Decrease the amount of energy used by the production processes
|Optimise use of heat exchangers and similar devices to utilise otherwise wasted heat
||Optimisation of energy flows in production processes
|Minimise losses from production facilities by good construction, service and fast repair. Also provide maximum insulation of walls, pipes and ceilings.
||Prevention of losses by leaks, oversized boilers and bad insulation
