CAHYA MATA SARAWAK SUSTAINABILITY REPORT 2015

21 CAHYA MATA SARAWAK SUSTAINABILITY REPORT 2015 ENVIRONMENT Waste Management Waste management involves the practice of collecting and disposing of waste (and effluents) produced in our plants. Improper waste management can potentially have negative effects on the community’s health, and similarly it can also negatively impact the health of the environment. Positive waste management systems, however, can prevent the negative impact that waste has on the environment. Recycling or reusing materials that have already been used is another environmentally friendly way of utilising waste. Solid Waste Solid waste refers to any garbage, refuse or sludge from a wastewater treatment plant, water supply treatment plant, or air pollution control facility and other discarded materials stemming from industrial and commercial operations and from community activities. Our Cement Division produces various solid waste over its annual production cycle. These consist of wooden pallets, zinc and acrylic cladding sheets, and old bag filters of varying sizes, to name a few. Our Cement Division does not record the weight of our solid waste as our focus is primarily on minimising or eradicating waste. General waste is usually separated and sold to a third party vendor for recycling. Wood waste is donated to a nearby bricks manufacturing company. Some of the waste components including spent oil are incinerated during clinker production. CMS Wires sells its waste iron oxide and scrap metal to a local steel manufacturer. In 2015, CMS Wires sold 42.96 MT of scrap. Scheduled Waste Scheduled waste is any discarded solid, liquid or contained gas or material that can no longer be used. It is hazardous and is difficult to dispose of safely without special technologies and facilities. At CMS Clinker, we produce relatively small volumes of scheduled waste. The types of scheduled waste that are generated are summarised in the table below. Type of Scheduled Wastes Waste Code Contaminated rags, plastics, paper and filters SW410 Spent oil, lubricant and grease SW421 Contaminated rags SW410 Contaminated spill kits SW410 • Container contaminated with laboratory chemicals • Drums contaminated with oil, lubricant and grease SW409 Obsolete laboratory chemicals SW430 Waste of lead batteries in whole or crushed form SW102 Waste of electrical and electronic SW110 The procedure of handling the scheduled waste is summarised below: 1. The operator ensures all generated scheduled wastes are properly stored in relevant containers. 2. Contaminated parts are cleaned with diesel before being disposed of at the scrap storage area. 3. Once the drum is full, it is transferred to the scheduled waste store. The total quantity of waste is recorded in a record book. 4. The Waste Management Team (WMT) Leader submits the records to the DOE on a monthly basis. 5. The WMT calls for disposal of waste, 180 days from the date the waste was generated or when the quantity reaches 20 MT, whichever comes first. PPES Works (Sarawak) Sdn Bhd adopts stringent scheduled waste practices which are also part of its Environmental Impact Assessment and Environmental Monitoring Programme. The company does not produce high quantities of scheduled waste. The Group does not produce or transport any waste deemed hazardous under the terms of the Basel Convention Annex I, II, III, and VIII. Air Emissions, Noise, Dust and Vibrations As a corporate body involved primarily in the manufacturing of business-to-business (B-2-B) products, we are focused on good environmental practice and conduct regular environment monitoring to keep our practices within the regulatory standards and to prevent industrial pollution. Air Emissions Management The results of CMS’ Total Suspended Particulates are presented on the following page. We have included three quarries; five monitoring stations at the Proposed Sarawak Museum Campus; and CMS Clinker’s waste gas stack, cooler stack and coal stack. All readings are within the Malaysian Recommended Environmental Air Quality Guidelines of 260 µg/m 3 . using other agents such as lime, emulsion, bitumen and soil stabilisers. As an environmentally-friendly company, CMS Pavement Tech promotes sustainable engineering and construction using locally-sourced, alternative materials. By tapping the company’s technology, clients can take advantage of cost savings, quicker construction as well as improved pavement performance and design life.
