We commit to optimize our process to reduce our reliance on natural resources and reduce our carbon and water footprints.
To achieve high efficiency production, we collaborate with industry partners to turn waste to material and convert waste to energy, hence reducing our reliance on natural resources. We optimize our process to save energy and reduce emissions. We adopt a risk-based reliability maintenance strategy to improve the reliability of our production lines.
The POLAB ACT machine at our laboratory is a compact and powerful system for quality control of cement, in which the process samples arrive in pneumatic delivery capsules and are automatically prepared for routine and chemical analysis.
我們化驗室所採用的POLAB ACT是一套先進精密而又高效能的水泥質量控制系統，生產過程的樣本透過氣動輸送系統運回POLAB ACT，POLAB ACT隨後會自動處理樣本並對其進行常規化學分析。
POLAB ACT provides the highest degree on automatically received or manually input samples and fulfills stringent requirements regarding reproducibility and freedom from contamination. The POLAB computer system AQCnet can also coordinate and monitor the operational sequence of the overall system and directly influence process control in the production.
The use of cement substitutes is a common practice throughout the global cement industry. Another common methodology to reducing emissions in cement production is from using alternative fuels, such as biomass and other waste materials. We have always considered alternative fuel use a win-win solution as it increases our profitability and enhances competitiveness while reducing our carbon footprint.
Despite prevalence in other countries, in Hong Kong, it is an unusual practice for a cement company to target locally available waste. To demonstrate the environmental and economic value, we conducted a trial burn programme of wood derived fuel to prove how GIC can collaborate with local waste management groups and resolve the waste problem of Hong Kong in a responsible and accountable manner. Under a special permit granted by the EPD in October 2018 and after Typhoon Mangkhut, approximately 263 tonnes of fallen trees and twigs were collected and burned in our plant as an alternative energy source in 2018.
The trial burn exercise has proven to be successful in showcasing our capacity for providing a high-quality standard of cement that diverts waste from landfill and incinerators and has minimal emissions.
Hong Kong residents and companies use a lot of glass for food and beverage needs, and despite being endlessly 100% recyclable, without loss in quality or purity, very little of it is recycled. Always thinking resourcefully, in 2017, we saw an opportunity to help divert Hong Kong's waste glass from landfill by using glass cullet as an additive during cement production. The glass cullet replaces between 1-2% of clinker and in 2018 we handled 3,560 tonnes, which is equivalent to around 2,500 tonnes in CO2 reduction while also diverting nearly 1,000 metric tonnes of glass from going to landfill every month. We target to convert around 16,000 tonnes annually (i.e. 1% of our clinker dosage) however achieving this goal is subject to the availability of glass supply and the logistics of working with waste glass collection service providers. The EPD supports this initiative as it is considered a viable solution that both diverts waste and reduces CO2 emission.
