An environmental project starts with a defined operating duty: what enters the system, how it varies, what result is required and how the plant can run it. IE expo Shanghai 2027 gives buyers access to water and wastewater, solid waste and recycling, air-pollution control, remediation, monitoring and related technologies. The useful comparison is between complete proposals built on the same site data, rather than equipment grouped under the same category name.
The 28th edition runs from 20–22 April 2027 at Shanghai New International Expo Centre. Its broad scope supports several distinct project missions.
| Buyer mission | Starting evidence | Useful result from the show |
|---|---|---|
| Treat or reuse industrial wastewater | Flow profile, composition, variability and target outlet | A process route with defined boundaries and remaining tests |
| Control an air emission or workplace source | Source, flow, pollutants, temperature and operating pattern | A collection-and-treatment concept sized to the actual duty |
| Handle a solid or hazardous waste stream | Waste description, quantity, variation, storage and destination | A route covering preparation, treatment, residues and outlets |
| Build or improve environmental monitoring | Measurement points, ranges, methods, data and reporting needs | An instrument and data system with calibration and service defined |
Choosing one primary mission gives the show visit a clear route. A wastewater reuse project, a dust and volatile-organic-compound project, a sludge-treatment line and an online monitoring network may share some suppliers, but they need different input data and acceptance evidence.
Prepare a duty data sheet
For wastewater, compile hourly and daily flow, peaks, production schedules, temperature, pH, conductivity, solids and the pollutants relevant to the process. Include sampling methods, test dates, variability across products or cleaning cycles, existing treatment steps, the intended reuse or discharge point, available sludge route, space, utilities, operator coverage and seasonal or planned production changes.
For air projects, define each source, capture point, air volume, pollutant and concentration range, temperature, humidity, particulates or aerosols, intermittency, fire or explosion considerations identified by the project team, existing ductwork and allowable pressure impact. Waste projects need composition, physical form, moisture, contaminants, quantity, storage, handling, transport and the planned route for recovered products and residues. Monitoring projects need parameter, range, expected interference, sample conditioning, calibration method, communication interface, data retention, alarms and reporting workflow.
Mark which figures come from representative measurements, design estimates or supplier assumptions. If current data is too limited for sizing, define a sampling or pilot plan before requesting a firm performance proposal. Suppliers can then state what additional evidence they need rather than hiding uncertainty inside a safety factor.
The required outlet also needs a clear basis. Record the product or process reuse condition, discharge or emission point, internal company criterion, contractual requirement and any applicable rule identified by the project owner. Final compliance interpretation and approval remain with the owner and relevant authorities; the show discussion should focus on the technical assumptions and evidence used in the proposal.
Compare the full process boundary
Ask each candidate to draw the route from inlet or collection point to treated output and residual stream. A wastewater package may include screening, equalisation, physical or chemical pretreatment, biological or membrane stages, polishing, disinfection, dosing, sludge thickening and dewatering. Air control may depend as much on source capture and duct design as on filtration, scrubbing, adsorption, oxidation or recovery equipment. Waste treatment may require sorting, size reduction, separation, drying, stabilisation, recovery and residue handling.
For every step, record design flow and load, expected removal or recovery, operating window, bypass and buffer conditions, chemicals or consumables, energy and utilities, instrumentation, controls, operator tasks, maintenance access and the destination of secondary waste. State which inlet conditions can reduce performance or damage the system and how those conditions will be detected.
Then define the supply boundary. Identify who provides process design, core equipment, tanks or vessels, pumps and fans, instruments, electrical panels, automation, software, piping or duct interfaces, civil and structural inputs, installation supervision, commissioning, training and performance testing. Component suppliers and system integrators can both be useful, but their quotations need separate scope columns.
Existing facilities add another layer. Record tie-in points, available footprint and headroom, utility limits, shutdown windows, upstream production constraints, downstream capacity and the systems that must keep operating during installation. A proposal should show how the new package connects to the plant, not just how it performs as a standalone skid.
Match evidence to the project risk
Request a preliminary process description, design basis, flow or mass balance, main equipment list, utility estimate, layout allowance, control description, expected consumables, staffing and maintenance assumptions. Ask which performance figures come from calculations, laboratory or pilot work, comparable installations or guarantees offered for the proposed project conditions.
A reference becomes more useful when its inlet, scale, process, outlet target and operating pattern resemble the buyer’s duty. Record the relevant differences and how the proposed design addresses them. A supplier-site test may demonstrate equipment construction or a treatment step; a customer-site reference may show longer operating behaviour. Access, data availability and permission to discuss performance need advance confirmation.
Pilot work is appropriate when influent or waste variability, treatability, fouling, media life, reaction conditions, residue quality or scale-up remains uncertain. Agree feed source and sampling, test duration, operating ranges, analyses, laboratories or measurement methods, material balance, consumable use, cleaning, failure observations and the decision criteria before the pilot begins. The report should retain unsuccessful conditions as well as the best result.
For monitoring equipment, evidence should cover the stated range and matrix, conditioning system, interference, calibration and verification, drift, maintenance interval, consumables, data integrity, alarms and recovery after faults. A display reading at the booth is a starting demonstration; the project decision needs evidence for the intended measurement point and operating environment.
Use site visits to close open questions
Visit an equipment supplier or integrator when the decision depends on engineering, fabrication, controls, testing or service capability. Confirm what is performed at the proposed address and which legal entity will contract. Follow the quoted configuration through design release, bought-out components, fabrication or assembly, material and weld records where relevant, instrument and software configuration, factory testing, preservation, packing and installation preparation.
At a reference installation, focus on the conditions that match the proposed duty. Review inlet and outlet records, operating stability, chemical and energy use, sludge or residue production, operator workload, maintenance, spare parts, alarms, shutdowns and changes made after commissioning, subject to the owner’s permission. An unrelated installation can still explain service practice, but it should be labelled as context rather than direct performance evidence.
Clarify the path from delivery to stable operation. Record installation responsibility, site readiness checks, commissioning steps, water or material used for startup, operator training, initial tuning period, performance-test conditions, handover documents, warranty start, remote support, local service and escalation contacts. For a multi-supplier system, give one party responsibility for coordinating interfaces and open items.
Build a comparable technical and commercial offer
Ask candidates to quote against the same duty sheet and to list exclusions and deviations. Separate process package, equipment, instrumentation, automation and software, tanks or structures, interconnecting works, freight, supervision, installation, commissioning, testing, training, initial chemicals or consumables, recommended spares and service. Keep capital price apart from estimated chemical, media, energy, disposal, labour and routine-maintenance requirements.
The final matrix should connect each inlet condition and required result to the proposed process step, design assumption, evidence, remaining test, supply owner, quoted scope, operating requirement and next decision. A technically strong IE expo visit produces a smaller number of clearly bounded proposals and a practical evidence plan for selecting between them.
