SmallBoss MBBR One-Stop and PVC Sheet Pile at 2026 IE Expo

From April 13 to 15, 2026, Tongxiang SmallBoss Special Plastic Products Co., Ltd. participated in the 27th Shanghai International Environmental Protection Expo (IE Expo), focusing on showcasing its full-process one-stop MBBR water treatment solution and core polymer PVC sheet pile technology. As Asia's most influential environmental protection professional event, this year's expo, themed "Green Leadership, Global Integration", brought together nearly 2,000 exhibitors from 20 countries and regions, covering 15 halls with 170,000 square meters of exhibition space.

As a national high-tech enterprise and specialized and sophisticated "Little Giant" enterprise from Tongxiang, Zhejiang, SmallBoss has been deeply engaged in environmental protection materials for over 30 years and MBBR water treatment technology for more than 20 years. The company exhibited its two core products: MBBR Bio Media and PVC Sheet Pile, demonstrating the hard-core strength of Chinese environmental protection new materials to the world.

SmallBoss Becomes a Highlight at the International IE Expo

This year's Shanghai IE Expo reached a new high in internationalization, with envoys and procurement delegations from the Netherlands, Norway, Argentina, Singapore and other countries gathering at the event. The "Global Business Lounge" accurately connected global resources, building a direct bridge for Chinese environmental protection enterprises to go global.

With its differentiated technical advantages, SmallBoss became a highly watched representative of specialized and sophisticated enterprises at the expo. Its booth attracted a continuous stream of domestic and foreign buyers, engineering parties and technical experts who stopped to consult and discuss cooperation.

Core Product 1: S-Type Patent MBBR Bio Media

MBBR Bio Media is the core product developed by SmallBoss through over 20 years of in-depth research in MBBR water treatment technology. It features a proprietary S-type patent structure, porous bio-affine formula and fluid dynamics optimized design. The core of MBBR process is the media, whose structure directly determines biofilm formation, fluidization state, treatment efficiency and operating energy consumption.

Unlike pure media manufacturers in the industry, SmallBoss is one of the few enterprises in China that can provide full-process one-stop procurement service for MBBR water treatment. We have broken the traditional "product-only" model and created a closed-loop innovation of service and technology, covering water quality analysis, process package design, core MBBR media supply, aeration system matching, on-site installation and commissioning, operator training and lifelong after-sales service.

Our products and complete solutions have been applied in hundreds of benchmark municipal wastewater upgrading and industrial wastewater treatment projects nationwide. Compared with traditional processes, it can increase treatment load without expanding tank volume, reduce sludge production by more than 30%, and has the advantages of high efficiency, energy saving and easy operation.

Core Product 2: Polymer PVC Sheet Pile

Polymer PVC sheet pile, known as the "green armor" for ecological revetment, is integrally formed with modified polymer materials. It breaks through the limitations of traditional steel (easy to rust) and concrete (heavy), with a compressive strength of 80MPa and a service life of over 50 years, and has obtained the Science and Technology Promotion Certification from the Ministry of Water Resources.

Its unique ecological hole design balances flood control safety and water connectivity, providing habitat for aquatic organisms and realizing the synergy of engineering safety and ecological protection. It is widely used in river regulation, cofferdam engineering and foundation pit support, and is the preferred material for zero-waste cities and water ecological restoration.

Industry Standard Editor Defines PVC Sheet Pile Technical Specifications

As the editor-in-chief unit of the group standard Technical Specification for Application of PVC Sheet Pile (T/CSPSTC 180-2025), SmallBoss has joined hands with top domestic research institutes and central enterprises including Hohai University, China Institute of Water Resources and Hydropower Research, and South-to-North Water Diversion Group to define industry technical standards from the source.

This standard has been officially released and implemented, providing authoritative technical basis for the PVC sheet pile industry. Relying on the technical accumulation as a standard setter, SmallBoss PVC sheet pile products fully meet national group standard requirements and have been successfully applied in national major projects such as Qinghai Salt Lake and Taihu Lake Island Cofferdam.

Based in Tongxiang, Going Global for High-Quality Development

The current environmental water treatment industry has completely shifted from the past "construction-focused, scale-focused" stage to a high-quality development stage of "standard upgrading, cost reduction and stable operation". Customers' core demand now is to achieve long-term stable effluent compliance with lower energy consumption and more mature processes.

There are three irreversible future industry trends: first, localization and high-end substitution of core materials; second, energy saving and consumption reduction will become a hard assessment index; third, customers no longer want single products, but full-process solutions that can truly solve problems.

Shanghai IE Expo is a top platform connecting global environmental protection resources. This exhibition is an important opportunity to showcase Tongxiang manufacturing, learn cutting-edge technologies and expand international markets. SmallBoss will continue to deepen the research and development of polymer environmental protection materials, promote technological iteration and scenario application, and help the integrated ecological and green development of the Yangtze River Delta.

From Tongxiang workshops to Shanghai exhibition stands, from micro-innovation to industry benchmark, SmallBoss's appearance is a vivid epitome of private environmental protection enterprises in Jiaxing adhering to industry, deepening segmentation and embracing globalization.
