9 Type Electricity Petroleum Mazut E n e r g y Consumption (energy unit/month) KW ,00 kg ,00 kg W a t e r Type Supply Consumption (m 3 / month) Quality Water Communal 3000 Drinking

10 Object Mechanical workroom Laundering and repairing Chemical Treatment (type and quantity) Manually Purgasol Place of delaying the waste Return into barrel The oil from the mechanical workroom is collected and sailed (MINOL Stip) The waste from the technological process is stored and returned back in the technological process

11 STOCKS (RESERVOIRS) All the reservoirs are located out of the technological process Reservoirs for mazut and petroleum are safely suited out of the process and are supported by safety ventilate and isolation; safety covered The storage of the basic raw materials like sinter magnesia, bauxite, etc. are stored in closed and safety concrete closed bunker The packing materials are stored in proper stockroom The chemicals and additives are stored in stockroom under the proper temperature, humidity, light.

12 WASTE FLOWS Waste water Type Quantity Further treatment No waste water / / Waste gases Type Quantity Further treatment Gases from boiler room m 3 /h No further treatment Gases from chamber furnace (mazut) Gases from chamber furnace (petroleum) m 3 /h m 3 /h No further treatment No further treatment Gases from ball mill m 3 /h Passes trough filter

13 WASTE FLOWS Waste packing materials Type Quantity (kg/month) Paper 300 Nylon 300 Quality Further treatment Big-beg bags 4000 Polypropylene Sales Waste materials Type Technological process Quantity (tones/month) Further treatment 35 Return into the production process Communal waste 3 To communal enterprise

14 MONITORING TECHNOLAB is the certificated laboratory for controlling the emissions Law for environmental protection Law for public clearning, colection and transportation of communal and technological waste Law for sanirationa and heltsh inspection Law for communal actiond Law for waste Law for water Law for ambient air Law for noise

15 ACCIDENTS AND ACTIONS OF LOCALISATION AND SANATIZATION Up to now there was no accident situation. The team manage to solve the problems on time and place. RECUCLING Closed cycle Waste is used in the process from the used refractories, porcelains,
