Recycled paper constitutes 28% of the overall paper usage at DYH facilities. In 2011, nearly 52,000 tons of recycled paper was used for newspaper production.
Wastewater as a result of the production process at the DYH facilities is collected by means of special wastewater plant. After physical treatment (grills, oil filter and sand filter), the wastewater is also biologically treated.
After the biological treatment, in accordance with the standards set by official institutions, the wastewater is discharged into appropriate environments from discharge points again approved by the same authorities.
The treatment plant is managed by the relevant departments at the Company. The treatment process is also overseen by official institutions through regularly collection of water samples.
Following the treatment, the treated sludge is kept at hazardous waste depositories in accordance with the standards set by the Ministry of Environment and then delivered to licensed companies for disposal.
Following the request made by the Istanbul Water and Sewerage Administration (İSKİ), an integrated chemical and biological treatment plant was constructed at the press facilities. Domestic wastewater is discharged without treatment to İSKİ canals, and mixed industrial wastewater is first treated in this plant and then discharged to the İSKİ sewage system according to discharging criteria.
Waste paper generated during production is stacked at collection points and disposed of as scrap for recycling. As of 2011, scrap companies are now required to be licensed by the Ministry of Environment.
Batteries and Accumulators
Waste batteries are collected in the collection bins of the Portable Battery Manufacturers and Importers Association (TAP) and delivered to the association for disposal. Waste accumulators are stored on concrete grounds that are impermeable to water and then delivered to licensed companies for recycling.
Film Developing Solutions
Fixing solutions collected in the conventional film developing equipment that is still being used in some of our enterprises are collected on site and in closed systems. These solutions are then delivered to licensed companies for recovery of silver.
Waste Aluminum Plates
After they are cleaned, aluminum plates used for printing are collected at waste collection points and then delivered to collection/recycling companies licensed by the Ministry of Environment for recycling.
The reservoir water and solvents used in printing are collected on site. The solvents are collected into drums and kept in plastic hazardous waste depositories in accordance with the standards set by the Ministry of Environment and then sent to licensed companies for disposal.
Despite domestic treatment, treated sludge from biological treatment plants is considered hazardous and is delivered to licensed disposal companies for disposal.
Waste Plastic Drums and Metal Barrels
Drums and barrels of chemicals used in production, such as reservoir water, solvents and oils (contaminated waste) are stored at waste collection points and later sent to firms licensed to dispose of these waste materials.
Waste Mineral Oil
When it expires, mineral oil used in the machine are collected on site and after being analyzed in laboratories licensed by the Ministry of Environment in terms of category, is delivered to licensed companies for recycling.
Scrap PCs and monitors, integrated circuits, semi-conductors, telephones, fax machines, photocopy machines, DVDs, VCRs, printed circuit sensors, cables, medical devices, printers, and the like are delivered to recycling companies licensed by the Ministry of Environment for recycling.
Scrap Fluorescent and Mercury-Vapor Light Bulbs
Scrap fluorescent and mercury-vapor light bulbs are kept in hazardous waste depositories in accordance with the standards set by the Ministry of Environment and are then delivered to licensed recycling companies for disposal.
Printer Cartridges and Toners
Cartridges and toners are within the recycling system of HP, which established a worldwide recycling system. As a result, HP supplies are preferably used throughout the Company and waste toners and cartridges are delivered to HP for recycling. Use of other brands in the Company is being reduced and these are separately delivered to licensed recycling companies for recycling.
The newspaper printing machines run on electricity and therefore no gas is emitted into the atmosphere during production. Since the heating systems at the presses and the office buildings are below 2MV, they are exempt from an emission permit within the Regulations for Industrial based Air Pollution Control and CO2 is released at minimum levels.
The cleanup of the environment surrounding the facilities is undertaken by firms on a regular daily basis. In addition, as per the Regulation on Soil Pollution Control, the Company's Environmental Control Department takes measures and posts warnings against soil pollution at production facilities.
Maintenance of Green Space and Planting of Trees
The greening of areas reserved as green space at all facilities is undertaken by specialist firms on a regular basis.
Environmental Health and Protection in Administrative Buildings
Waste oil from the generators and the vehicles of the Company is delivered to licensed recycling companies.
Launched in 2011, the new headquarters building of the Company is equipped with state-of-the-art cooling systems manufactured in line with the EU environmental policy, using R 410 and R 132. Attention is paid so that all the newly purchased coolers and equipment with coolers use environmentally friendly gases. The import, use and delivery of the cooling gases to the end-consumer are done in accordance with the regulations of the Ministry of Environment. The maintenance of the cooling systems at the administration building of the Company is carried out periodically by contracted authorized technical services.
The new Company building is equipped with state-of-the-art and environmentally friendly fire fighting systems. The number of fire extinguisher tubes was reduced, and new, environmentally and health friendly systems that use FM 200 and Novac1230 were introduced in compliance with EU standards. Fire extinguisher tubes are inspected biannually by contracted authorized technical services.
Owing to the thermal insulation technology of the building, the consumption of natural gases for heating and the consumption of electricity for cooling have been decreased and in turn carbon emissions were reduced.
No law suits have been filed against the Company due to environmental damage claims.
