随着“源头降碳—末端循环”从理念走向工程化落地，行业已进入必须以可量产的工艺窗口与可追溯的数据闭环来验证成效的深水区；这一逻辑也正在成为产业链推进循环经济的科学共识。在“十五五”生物制造新材料、固体废物循环利用与“双碳”目标高质量推进的背景下，产业链竞争焦点正由“材料标签”转向“系统落地”。
在城市固体废物高效利用体系中，“纸代塑2.0”的关键价值在于：纸基一次性餐饮具及食品包装所使用的优质纸纤维具备可回收、可再浆的高价值循环潜力；而水性阻隔技术只有在不牺牲循环友好性的前提下，同时兼顾阻水阻油性能与产线制造适配，才能沉淀为可核算、可审计的真实减碳收益。因此，面向城市应用的纸基解决方案必须同时满足三点：源头更低碳、末端高价值循环可验证、降解可选的特定场景兜底路径。
带着这一产业命题，都佰城团队赴湖北宜昌，参加在微构工场与安琪酵母合资共建的湖北微琪生物PHA万吨级生产基地举办的产业链交流活动，并走进微构工场PHA万吨级产业化工厂现场参观与研讨，推动BIOTEN™博碳水性PHA阻隔涂层在纸基食品包装与纸质餐具领域的产业化应用进入“加速区”。
同时，交流中亦提及PHA产业原创技术的重要性。PHA领域重要推动者、被业界誉为“PHA发明家”的陈国强教授长期推动PHA生物合成与产业化发展，为PHA创新应用产品走向全球奠定了坚实基础。

水性阻隔进入产业化加速区的三项条件
围绕水性阻隔涂层在纸基食品包装与纸质餐具中的规模化应用，产业链需对齐三项关键共识：1、性能稳定可复现：高阻水/阻油、阻潮、阻氧、耐热、挺度保持、气味与食品接触体验等指标，必须实现批次一致与场景稳定，从“实验室达标”升级为“工程稳定”。2、工艺窗口可量产：涂布造纸端与制品成型端需要同频优化，锁定可规模化的涂布、干燥、成型与热封窗口，确保产线效率与良率稳定，真正形成可交付能力。3、末端路径可循环、可验证：以城市固废体系现实为前提，优先走“可回收、易再浆”的高价值循环路线，用闭环数据验证真实减碳——让绿色从“表达”变为“证据”。

方向正确，定力很重要：把路线图变成“产线标准”
本次宜昌交流的价值，不止于观点对齐，更在于推动中国产业链以共同指标体系与联合验证机制加速落地，把“方向一致”进一步升级为“标准一致”——以可量产的工艺窗口与可追溯的数据证据为核心，沉淀为对标国际、可复制推广的产业化新范式，并为形成国际可比、可采信的评价体系贡献中国方案。
围绕纸基食品包装水性阻隔系列产品，都佰城自2022年起与战略合作伙伴巴斯夫、金光集团APP持续深化协同，锚定“替塑、降碳、易回收、高再浆”的共同目标，系统推进纸基与水性阻隔体系在涂布端与制品成型端两条产线的工艺窗口产业化验证，加速固体废物资源化的高价值循环——让“循环”不仅是理念，更成为可测量、可审计、可规模化交付的产业能力。
我们坚定推动的“小纸杯、撬动大环保”，之所以能够穿越争议并形成共识，根本原因在于：纸杯是高频、高量、强体验的“真实场景试金石”。当一只小纸杯能够同时做到源头更低碳、使用体验可复现、末端循环可验证，它所打通的就不仅是一项材料替代，而是一条可复制的低碳循环路径——让“循环价值”从口号变成标准、从实验变成产线、从样板走向规模。
我们将以此为起点，持续把纸基餐饮具与食品包装的循环模式做成产业链协同降碳的样板，面向全球市场输出可验证、可复制的解决方案。
下一步，我们将继续与伙伴协同推进：在源头端进一步强化PHA生物基体系的低碳属性与可核算性，持续提升“源头降碳”的确定性；在制造端统一评价口径、锁定关键工艺窗口、开展应用导入与终端验证，让博碳生物基PHA水性阻隔涂层在真实产线、真实订单、真实应用中跑稳、跑一致，推动纸基包装低碳化与循环化升级进入可复制、可规模化、可面向全球市场推广阶段。
用一只小纸杯，把循环经济从理念做成标准；把低碳从叙事做成产线；把中国方案做成全球可采信的确定性。

As "carbon reduction at the source and recycling at the end" moves from concept to engineering implementation, the industry has entered a deep-water area where results must be verified with process windows that can be mass-produced and traceable data closed loops; this logic is also becoming a scientific consensus for the industrial chain to promote circular economy. In the context of the “15th Five-Year Plan” for biomanufacturing of new materials, solid waste recycling and the high-quality advancement of the “double-carbon” goal, the focus of competition in the industry chain is shifting from “material labeling” to “system implementation.”
In the efficient utilization system of municipal solid waste, the key value of "Paper for Plastic 2.0" is that the high-quality paper fiber used in paper-based disposable tableware and food packaging has high-value recycling potential that is recyclable and repulpable; and water-based barrier technology can only be converted into real carbon reduction benefits that can be accounted for and audited without sacrificing cycle friendliness, taking into account both water and oil-blocking performance and production line manufacturing adaptation. Therefore, paper-based solutions for urban applications must meet three points at the same time: lower carbon at the source, verifiable high-value recycling at the end, and optional degradation paths for specific scenarios.
With this industry proposition in mind, the DBC team went to Yichang, Hubei, to participate in an industrial chain exchange event held at the Hubei Weiqi Biological PHA 10,000-ton production base jointly built by Bluepha and Angel Yeast. They also visited the Bluepha PHA 10,000-ton industrial chemical plant for on-site visits and discussions, promoting the industrial application of BIOTEN™ BIOTEN water-based PHA barrier coating in the fields of paper-based food packaging and paper tableware into the "acceleration zone".
At the same time, the importance of original technology in the PHA industry was also mentioned in the exchange. Professor Chen Guoqiang, an important promoter in the PHA field and known as the "PHA inventor" in the industry, has long promoted the development of PHA biosynthesis and industrialization, laying a solid foundation for innovative PHA application products to go global.

Three conditions for water-based barriers to enter the industrialization acceleration zone
Regarding the large-scale application of water-based barrier coatings in paper-based food packaging and paper tableware, the industry chain needs to align with three key consensuses: 1. Stable and reproducible performance: high water/oil barrier, moisture barrier, oxygen barrier, heat resistance, stiffness maintenance, odor and food contact experience and other indicators. It must achieve batch consistency and scene stability, and be upgraded from "laboratory compliance" to "engineering stability". 2. The process window can be mass-produced: the coating papermaking end and the product forming end need to be optimized at the same frequency, locking the scalable coating, drying, forming and heat sealing windows to ensure stable production line efficiency and yield, and truly form deliverability. 3. The terminal path is recyclable and verifiable: Based on the reality of the urban solid waste system, priority is given to high-value recycling routes that are "recyclable and easy to repulp", and closed-loop data is used to verify real carbon reduction - turning green from "expression" to "evidence".
DBC: BIOTEN bio-based water-based system, covering paper-based and dispersion scenarios
In addition to the paper-based food packaging/paper tableware water-based PHA barrier coating that is the focus of this discussion, DBC has formed a multi-scenario product and system solution matrix around the overall route of "carbon reduction at the source, recycling at the end, and optional degradation":
Bio-based water-based coating system product solutions (coatings, coatings, emulsions, and binder system solutions for multi-field scenarios); paper-based water-based barrier emulsions (taking into account barrier performance, heat sealing process adaptation, and reslurry cycle friendliness); seed coating is fully biodegradable Coating (a controllable degradation solution for underground fate scenarios); fertilizer slow-release pills (bio-based coating system, supporting release curve regulation and efficiency improvement); agricultural mulch film full biodegradation system solution (material system-processing technology-application verification integration).
Up to now, DBC BIOTEN series products have obtained more than 20 invention patents authorized by the State Intellectual Property Office. The innovative application technology system supports the continuous iteration of key formulas, process windows and application scenarios, providing a long-term technical base for the industrialization promotion of PHA.
The direction is right and determination is very important: turn the roadmap into a "production line standard"
The value of this exchange in Yichang is not only the alignment of opinions, but also the acceleration of the implementation of China's industrial chain with a common indicator system and joint verification mechanism, and the further upgrade of "unanimous direction" to "unanimous standards" - with process windows that can be mass-produced and traceable data evidence as the core, it will be precipitated into a new industrialization paradigm that benchmarks internationally and can be replicated and promoted, and contribute Chinese solutions to the formation of an internationally comparable and acceptable evaluation system.
Focusing on the series of water-based barrier products for paper-based food packaging, DBC has continued to deepen collaboration with strategic partners BASF and APP Sinar Mas since 2022, anchoring the common goal of "plastic replacement, carbon reduction, easy recycling, and high repulping", and systematically promoting paper-based and The water-based barrier system is industrially verified in the process window of the coating end and product molding end of the two production lines, accelerating the high-value recycling of solid waste resources - making "circulation" not only a concept, but also an industrial capability that is measurable, auditable, and deliverable on a large scale.
The fundamental reason why the "small paper cups, leveraging large environmental protection" we firmly promote can overcome controversy and form a consensus is that paper cups are a "real-life touchstone" for high frequency, high volume, and strong experience. When a small paper cup can simultaneously achieve lower carbon origin, reproducible use experience, and verifiable terminal recycling, it opens up not only a material substitution, but a replicable low-carbon cycle path - allowing "circular value" to change from a slogan to a standard, from an experiment to a production line, and from a model to a scale.
We will use this as a starting point to continue to make the circular model of paper-based tableware and food packaging a model for collaborative carbon reduction in the industrial chain, and export verifiable and replicable solutions to the global market.
In the next step, we will continue to work with our partners to further strengthen the low-carbon attributes and accountability of the PHA bio-based system at the source, and continue to improve the certainty of "source carbon reduction"; at the manufacturing end, unify the evaluation caliber, lock key process windows, and carry out application introduction and terminal verification, so that BIOTEN bio-based PHA water-based barrier coating can run stably and consistently in real production lines, real orders, and real applications, and promote the low-carbon and circular upgrade of paper-based packaging into a stage that can be replicated, scaled, and promoted to the global market.
Use a small paper cup to turn circular economy from concept into standard; turn low carbon from narrative into production line; turn China's plan into globally acceptable certainty.
