At the moment, we have 35 projects across the nation. Our total capacity is 51,990 tons in terms of daily handling of municipal w aste. 27 projects already commissioned and in operation. The rest are being planned and constructed according to the original time schedule. In 2021, with our concerted effort, we have achieved early completion and commissioning of some newly established projects. New projects for the year, nine in total. Total scale per day, 12,100 tons, including those in Yingkou, Ruili, Baoding, Machong [Yuan Qi], [Huanshan], Phase Two, Xiangyun, and Liping projects have already started operation, creating good contribution to the Group. For new ones, we have obtained three projects and one expansion project, including Changning, Huizhou, Yixian, and Phase Two of Zhongshan. Newly added projects, daily capacity is 5,050 tons, expanding our portfolio further. That includes the handling of municipal waste.

Per ton generation level, 395 kWh, which is very outstanding among our peers. Concerning the operations of our plants, as shown on page 11 -page 13 of our PPT, our efficiency level continues to improve with good productivity and efficiency. The average power sold and generated is 86.8%, stating that our self-use ratio is low with high efficiency. Average utilization of our plants is 110.6%, showing our very high level of operating efficiency. Among 35 projects that we have, 16 of them are in Guangdong Province, which is 48.6%.

Looking into the future with the 14th Five-Year Plan, by 2025, we need to reach a specific target for handling capacity municipal solid waste. towards the end of that year, we need to reach utilization rate of 60%. Whole nation capability needs to reach 800,000 tons / day and municipal solid waste incineration capacity 65%. We will continue to enter this phase of refined management. We continue to stay very close to our partners to expand our project and resources and extend our influence upstream and downstream to realize asset-light operations.

We will continue to grasp opportunities to realize healthy growth and create better return for the Group, our shareholders, and all stakeholders. Now, I will pass the time to my colleague, Ms. Lisa Wong. Thank you, Mr. Yuan. Good afternoon. I will now take you through the performance highlights of 2021 for the Group. We sustained a growing trend and achieved outstanding results in 2021. We realized some new peaks. Our revenue realized in the year was HKD 6.795 billion, up 36.2%, mainly because of the growth in terms of our operations, in terms of power generation, sales, and garbage handling. Gross profit grew by 36.6% to HKD 2.11 billion. Attributable profit, HKD 1.322 billion in 2021, up 25.5%. Profit margin, 19.5%. Earnings per share, HKD 0.544, up 25.4%. Our different segments. You can see that power sales and waste management revenue increased by 45.3% to HKD 2.997 billion, taking up 44.1% of total revenue, mainly because of the enhancement of our operational capability and also newly added capacity, 12,100 tons. We achieve more than 50% growth in terms of whole year handling capacity and power generation volume. For the environmental, hygiene, and other services, we reached HKD 167 million, up by 37.3%. Our project construction services, up by 29.9% to HKD 3.51 billion, realizing our whole year target. Our financial income increased by 16.3% to HKD 114 million, which is 1.7% of the total number.

We realized HKD 1.496 billion, up 50%. As for the power sales and waste management fee revenue, it contributes 70% of our profit. We've done a lot of technological advancement, more R&D investment, and reducing our cost, higher level of efficiency, realizing such outstanding performance.

The asset debt ratio increased by 6.1% last year to 63.6%, and the net debt to equity ratio, 123.8%. With 11 projects being constructed and commissioned, our total asset has grown to HKD 24.4 billion. With those already being operated, we continue to record increase in terms of capital inflow, up by 35.5% to HKD 1.755 billion. Overall speaking, we believe that the debt level is well within the range of expectation and control. We reached the commissioning peak in 2021, and afterwards, we will sustain stable inflow of cash. We have already set up a number of monitoring measures in terms of our debt level. We will continue to be prudent and consider diversification of sources of capital to reduce our financing cost. While we have more debt, our interest cost from the bank is actually decreasing. In 2021, the average is 4.4%, which is lower than 4.65% in 2020. Our operating cash flow continues to climb. The interest multiplier is 4.4 x, reflected very good operational levels of the Group.
