Amazon gives green light to new solar projects in the US and Spain

CNBC | December 03, 2019

Amazon revealed details of new renewable energy projects in the U.S. and Spain Tuesday, with the tech giant seeking to ramp up the greening of its operations. Together, the three solar projects are expected to generate nearly 700,000 megawatt hours of energy per year, which is enough to power over 67,000 homes, according to the firm. The project in Spain will be southeast of the city of Seville and have a capacity of 149 megawatts (MW). The solar facilities in the U.S. will be in Lee County, Illinois and Northern Virginia, and will amount to a combined 180 MW. Amazon said that, once finished, the solar facilities would supply energy to its fulfilment network in Europe as well as Amazon Web Services data centers. While Amazon is aiming to green its operations through the development of renewable energy facilities, it is not immune from criticism.

Angel Yeast Strengthens Low-Carbon Measures to Advance Global Sustainable Development

Capstone Green Energy | March 14, 2022

Angel Yeast Co., Ltd., a publicly traded global yeast and yeast extract company, has achieved another milestone in its green quest toward carbon neutrality by being awarded one of China's "Green Factories" by the Ministry of Industry and Information Technology. The award demonstrates its unwavering dedication to reducing its operations' carbon footprint and demonstrates its tremendous and long-standing commitment to energy conservation and environmental protection. "As a leading global yeast innovator dedicated to bringing healthy and nutritious yeast-based products to customers worldwide, Angel Yeast shares the global responsibility to drive forward sustainable development by continuously advancing our pledge to reduce energy consumption and carbon emissions. The recognition from China's Ministry of Industry and Information Technology marks another major step for Angel Yeast in our drive to help China and the world accelerate towards the net-zero goal, " -Xiao Minghua, General Manager of Angel Yeast. Angel Yeast has increased investment in its manufacturing facilities to equip them with various carbon-reducing solutions—including energy-saving equipment and waste heat and pressure recovery—to reduce energy consumption and meet the company's new green energy production requirements. The company has increased its reliance on solar energy while decreasing its dependency on fossil fuels. Angel Yeast's factories can now recover waste heat created during manufacturing, increasing energy efficiency and reducing steam use. On the other hand, Angel Yeast can use more power because it uses cutting-edge water recycling technology in its business. In 2021, Angel Yeast began work on adding magnetic levitation fans at its Suixian and Binzhou manufacturing facilities. As a result, all of Angel Yeast's manufacturing facilities now include magnetic levitation fans. In addition, Angel Yeast also enhanced the boiler automation for its Egypt-based company in the same year, installing magnetic suspension chillers for its yeast manufacturing plant in Chongzuo. Another thing that happened this year was that Angel Yeast made twenty-eight technological changes to its plants worldwide. This meant that the company cut its carbon dioxide output by 19,700 tons, cut its power consumption per ton of yeast by 1.4 percent, cut its steam consumption by 2.5 percent, and cut its water consumption by 3.1 percent.
