We are mindful about sustainability from an environmental perspective. In operating our businesses, we are at all times committed to protecting the environment and complying with all applicable environmental laws and regulations. As part of our efforts to protect the environment, we promote effective management of emissions, waste, biodiversity and water. The following measures that are in place highlight our approach to environmental protection.
Our facilities report real-time emissions data from the plant to the respective Department of Environment (“DOE”) database for online monitoring by the regulator. To ensure compliance with emission limits, our plants employ a stringent emissions control equipment maintenance schedule and ensure optimal operational efficiencies. All greenhouse gas (“GHG”) and non-GHG emissions produced by Malakoff’s local generating facilities are directly related to fuel property and combustion process. Emission produced by Malakoff’s local generating facilities are as follow:
To reduce the impact of non-GHG emissions from our plants, Malakoff’s facilities are equipped with the following:
• Filtration equipment to reduce PM emissions – an electrostatic precipitator and fabric filter are installed at TBP Plant and TBE Power Plant respectively;
• Flue Gas Desulphurisation ("FGD") to reduce Sulfur Oxide ("SOx") emissions; and
• Stage combustion to reduce Nitrous Oxide ("NOx") emissions; and
• Dry low NOx combustion systems for our gas turbines plants.
GHG production is minimised though efforts to optimise the units’ generating efficiency.
Coal ash is the by-product of coal combustion at coal-fired power plants, and the disposal of coal ash is always key to coal fired power plant operations. There are two types of coal ash generated, namely Fly Ash and Bottom Ash. Fly Ash is a light and fine particle that is driven out from the boiler by flue gas, while Bottom Ash is a clinker-like non-combustible residue of the coal combustion that is usually collected from the bottom of the boiler. The coal ash is either stored in the Ash Pond or sold to cement or concrete producers.
In 2016, the 3,100 MW coal-fired power plants at Tanjung Bin generated about 50,000 metric tonnes of Fly Ash and 10,000 metric tonnes of Bottom Ash every month.
As part of Malakoff’s effort to manage waste, all of the Fly Ash generated was sold to cement producers to produce pulverized fuel cement. The Bottom Ash, however, was stored in the Ash Pond located inside the plant complex.
Environmental Monitoring Procedures (“EMP”) have been implemented at all sites under a monitoring programme on the environmental impact of plant operations. In 2016, sampling and analysis of the environmental related parameters were conducted by an external laboratory with DOE accreditation. The monitoring parameters included emissions, effluent, marine water, ground water, river water, and biological parameters (for example mangroves, fishes, birds, and turtles).
Malakoff’s plants use sea water for process cooling purposes and raw water for general administrative and process requirements. Water used for processes is mainly to replenish water and steam loss to the environment. We obtain our raw water supplies from respective state water supply companies i.e. Perbadanan Pembekalan Air Pulau Pinang ("PBAPP"), Syarikat Air Johor ("SAJ") and Lembaga Air Perak ("LAP").
Malakoff is committed to minimising any disruption to the environment from its usage of natural sources of water (e.g. seawater) in its production process. It does this through a diligent monitoring regime and by employing engineering solutions for continuous process improvement. At our Tanjung Bin site, the Management of ash pond water has reduced raw water consumption by 20 percent contributing towards a savings of RM1.18 million in raw water costs per annum, while ensuring environmental compliance (e.g. ash pond water level). In addition, the Tanjung Bin site also has in place rainwater harvesting system, which is used for cleaning purpose around the plant area.
Towards A Sustainable Future
As a conscientious corporate citizen, Malakoff remains deeply committed to balancing out its good economic performance with responsible environmental and social considerations. Even as we set our sights on delivering a sustainable performance on the EES fronts, we will endeavour to ensure that the notion of sustainability becomes embedded within our working culture in a more prominent manner.
To this end, the Group is committed to integrating the sustainability agenda into our overall strategy and operations in a more distinct manner for the long-term as we acknowledge this is key to the success of our business. Going forward, we will focus our efforts on delivering a more comprehensive Sustainability Statement come the next reporting cycle.
In all that we undertake, we will work hard to deliver true and sustainable value as well as establish enduring ties with our diverse stakeholders so that Malakoff strengthens its reputation as a model for responsible corporate behaviour.
