Group 1 - Avantium raised a total of €84.8 million (approximately 700 million RMB) through equity financing, exceeding expectations [2] - The financing included €65.4 million from a fully underwritten and committed share placement, and an additional €19.4 million from an extra placement, which included €15 million in new ordinary shares allocated to the Dutch government [2] - The CEO of Avantium stated that the funds will accelerate the company's transition to sustainable materials and aim for EBITDA breakeven by 2027 [2] Group 2 - Avantium has successfully launched its Sugar Dehydration Unit (SDH) to convert plant sugars into the key intermediate MMF (Methoxymethylfurfural), with utility systems operational and purification units in the commissioning phase [2] - The company has signed 20 purchase agreements for PEF, covering various applications such as bottles, fibers, and films, with a total contract value exceeding €100 million [3] - Avantium expects commercial operations to begin in Q1 2026, with its 100% plant-based recyclable material PEF (branded as releaf®) available to consumers [4]

Core Viewpoint - The company, Jupeng Bio, is the only global entity with an integrated technology chain for producing bioethanol and green methane from biomass gasification and gas fermentation, along with single-cell protein products [1][2]. Group 1: Technology Overview - Biomass Gasification: Converts carbon-containing biomass waste into synthesis gas, which can produce various green fuels and chemicals [3]. - Gas Fermentation: Includes CO/CO2 fermentation technologies for ethanol production and CO2 coupling green hydrogen fermentation for green methane, serving as effective pathways for CO2 direct reduction and efficient green hydrogen application [3]. - Single-Cell Protein: A high-nutrition and high-value biological product that can be used as aquaculture feed or developed into high-end downstream products such as peptides and culture media [4]. Group 2: Project Developments - In 2013, the first integrated demonstration plant for biomass gasification and gas fermentation to produce fuel ethanol was established in Florida, processing 250,000 tons of biomass annually and producing 24,000 tons of bioethanol, along with 6 MW of electricity [9]. - Jupeng Bio partnered with Shanxi Lu'an Chemical Group to construct an industrial waste gas fermentation plant in Changzhi, Shanxi, which began operations in October 2021 and has been validated for large-scale commercialization [9]. - A large-scale commercial facility with a capacity of 100,000 tons/year of ethanol and 20,000 tons/year of single-cell protein is set to begin construction in Ordos, Inner Mongolia, in November 2024 [9]. Group 3: Recognition and Certifications - In 2024, Jupeng Bio was recognized as a national high-tech enterprise and a "specialized, refined, and innovative" small and medium-sized enterprise in Beijing; the Shanxi plant was also recognized as one of the first high-tech enterprises in Shanxi Province [10].
