Waste Categorization

Hazardous Wastes Streams Contaminated Soil OBM Cuttings Medical Waste Mercury Waste Hazardous Wastes Streams Chemical Waste Oil Sludge NORM Waste E-waste Spent Lubricants

Hazardous Wastes Management Waste Stream Current Practices Contaminated Soil • Bioremediation at waste management facilities • Working with regulators to evaluate reuse options for road construction OBM Cuttings • Treated using thermal desorption unit • Sending to cement company Oily Sludge • Treated using centrifugal separators and recovered oil NORM Waste • Decontamination of the equipments, storage of removed scale and contaminated soil Chemical Waste • Solidifications • Neutralization and disposal in chemical pits Medical waste • Incinerator

Non-hazardous Wastes Streams Wood Waste Plastic Metal Waste Food waste Non-Hazardous Wastes Paper & Cardboard Streams Agriculture Waste Construction & Demolition

Non-Hazardous Wastes Streams Waste Stream Current Practices Plastic, Wood and Paper / Cardboard Construction and Demolition Food Tires • Accumulated in waste facilities, • Some quantities given for recycling • Landfill– Planned to be recycled • Landfill through trenching • Storage at Facilities

Waste Management Challenges Ø Insufficient storage capacity with increasing waste quantities. Ø High costs of wastes treatment with No potential for reuse. Ø Inadequate segregation at source. Ø Remoteness of the waste facilities- transportation cost Ø Absence of waste recycling/ treatment facilities in the country.

PDO Waste Management Initiatives ü Awarded Hazardous Waste management to international company ü Waste recycling and segregation ü Food waste reduction campaign ü Estidama (Sustainability) campaign. ü Work with local parties e. g. Be’ah, and the Ministry of Environment and Climate Affairs (MECA) to establish recycling facilities (ICV opportunity). ü Explore potential to utilized waste-toenergy in PDO 14

Way Forward ü Explore methods for waste minimization at source. ü Increase awareness among company staff and contractors community. ü Focus on possible reuse or recycling opportunities of waste streams (e. g. re-use of construction waste for road construction) ü Using Suitable technologies to treat each waste stream as specified by National and International standard ü Work together with The Ministry of Environment and Climate Affairs (MECA) in Oman, Be’ah and other bodies to investigate waste reuse opportunities ü Investigate Waste-to-Energy opportunities
