The environment is contemporary considered as of being most valuable wealth and common heritage of the mankind but it value is underestimated and therefore still not appropriately and adequately protected. Meat and poultry processing industry are belonging to those industrial activities which still have to be considered as of not being very friendly to the environment. Aiming at necessity of limiting and/or eliminating of the harm for the environment originating from technologies and processes used at present by the meat and poultry processing enterprises, new technologies and facilities, friendly to the environment, mainly to the air, are implemented in inedible raw materials rendering plants. Nowadays technologies and facilities applied in curing of meat and smoking of processed products could also be considered as of being friendly to the environment. Such opinion is based, among others, on new technologies of smoke generation, recirculation of smoke in smoking chambers, catalytic decontamination of the exhaust smoke, etc. Undervalued, although very promising, are still such an environmentally friendly techniques and technologies, mainly physical one and so called unconventional, in form of electromagnetic radiation such as: ultraviolet, ionising, microwave, high frequency electric and/or magnetic fields as well as ultrafiltration and pascalization. However, all of them are still applied in very limited technological operations. Summing-up this brief review regarding the environment friendly technologies typical for meat and poultry industry, seem ’s to be appropriate and justified: to quote a fragment of the HEILDERBERG APPEAL for world-wide necessity to protect our environment: „The greatest evils which stalk our Earth are ignorance and oppression, and not Science, Technology and Industry whose instruments, when adequately managed, are indispensable tools of a future shaped by Humanity, by itself and for itself, overcoming major problems like overpopulation, starvation and worldwide diseases”.
