Guideline | Reason
|
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
