They must be managed in compliance with relevant national regulations to prevent environmental pollution and legal liabilities. Below are the handling methods and key notes: I. Classification and Labelling 1. Waste Classification Waste gun wash solvent: Contains paint residues and organic solvents (e.g., acetone, xylene, etc.). Waste solvents / thinners: May contain volatile organic compounds (VOCs) such as toluene, ethyl acetate, methanol. These wastes are generally classified as HW12 (Dye and Coating Wastes) or HW06 (Organic Solvent Wastes) under China’s National Hazardous Waste Catalogue (2021 Edition), with corresponding waste codes (e.g., 900-252-12, 900-404-06). HW coding is China’s domestic hazardous waste classification system. For EU, US and most other global markets, equivalent classification follows local hazardous waste /spent solvent regulations (e.g., EPA RCRA in the US, Waste Framework Directive 2008/98/EC in the EU). 2. Standard Labelling Store in dedicated containers that are leak-proof and corrosion-resistant. Affix hazardous waste labels indicating contents, hazard properties (e.g., flammable, toxic), generation date and other required information. II. Legal Disposal Options 1. Engage a Licensed Disposal Contractor The waste must be handed over to an entity holding a Hazardous Waste Business License (qualified enterprises can be verified via the local ecological and environmental authority). Sign a disposal contract and complete the Hazardous Waste Manifest to ensure full traceability throughout the whole process. 2. Common Treatment Technologies Distillation for Recycling: Part of the spent solvent can be purified by distillation for reuse (professional equipment is required). Incineration: High-calorific-value waste may be sent to a hazardous waste incineration plant for harmless treatment. Physicochemical Treatment: Such as neutralization, precipitation, etc., which must comply with environmental protection standards. Chongqing JBETT Circular: Solvent Recovery Equipment with an Explosion‑proof Integrated Structure Design. Only 5–10% residue remains after recovery, achieving over 90% hazardous waste reduction. 3. Prohibited Activities × Discharging directly into sewers, soil or the atmosphere. × Unauthorized incineration or mixing with domestic waste for disposal. × Collection by unlicensed entities or individuals (likely to cause secondary pollution and legal risks). III. Waste Reduction and Compliance Management 1. Source Reduction Adopt high-efficiency spraying technologies (e.g., electrostatic spraying) to cut the generation of spent solvents. Use recyclable eco-friendly cleaning agents (e.g., water-based gun wash solvent). 2. Record-keeping and Declaration Establish hazardous waste management records to document the quantities generated, stored and transferred. Submit annual declarations of waste type, quantity and destination to the local ecological and environmental authority. 3. Emergency Response Measures In case of leakage, immediately contain it with absorbent materials (e.g., sand, activated carbon) to prevent spread. Equip storage areas with fire and explosion protection facilities (e.g., anti-static devices, ventilation systems). IV. Legal Liabilities Under local environmental legislation in each jurisdiction, illegal discharge or dumping of hazardous waste may attract substantial fines, ranging from the equivalent of CNY 100,000 to 5,000,000. Severe breaches may lead to criminal liability. Recommended Steps Contact your local environmental authority to obtain a list of licensed hazardous waste disposal service providers. Train employees on hazardous waste classification and storage requirements. Conduct regular audits of disposal workflows to maintain regulatory compliance. Professional and compliant handling helps fulfil environmental responsibilities and mitigate legal risks. For region‑specific or industry‑specific regulatory requirements, please consult your local environmental authority for further guidance.

Our explosion‑proof solvent recovery machine has been successfully commissioned and put into formal operation on site, for recycling waste ethyl acetate generated from small printing presses. The customer is a local manufacturer specialized in flexible packaging printing. Previously, the enterprise upgraded its paint formulation system to cut down solvent waste output and achieved remarkable results for most solvent streams. Even so, ethyl acetate waste from their small printing lines remained an ongoing challenge. Ethyl acetate is widely used in the printing industry, yet it is highly volatile and flammable, with a boiling point of 77.1°C and an extremely low flash point. Hazardous waste disposal costs are high, and local environmental supervision requirements are strict. Without proper on‑site recovery equipment, manufacturers face continuous expense pressure and potential safety risks. After full communication on waste characteristics, site safety standards and production layout, we recommended our explosion‑proof solvent distillation recovery solution, which is specially optimized for low‑boiling flammable solvents such as ethyl acetate. The equipment adopts all‑stainless‑steel structure, stable temperature control system and batch distillation workflow, designed to separate clean, reusable ethyl acetate from contaminated printing waste solvent. Recently, the customer finished installation, commissioning and trial run, and sent us on‑site footage of the machine in operation. Clean recovered ethyl acetate flows steadily out of the distillation unit and is collected directly into containers for reuse in their printing production.  Customer feedback: “We’ve started the process!!! Thank you, everything is working! We’re satisfied.” The recovered ethyl acetate can be fed back directly into the printing process, helping the customer slash purchases of fresh solvent and drastically reduce the quantity of hazardous waste that needs outsourced disposal. It delivers dual value: economic savings and environmental compliance. We are thrilled that our solvent recovery system has passed real‑world production testing and earned the customer’s recognition. The customer also mentioned they are currently enjoying a vacation in France and promised to send more operation photos and feedback after returning to the factory. At Chongqing JBETT Environmental Technology, we keep focusing on customized waste solvent recycling solutions for global printing, coating and chemical clients. Our product portfolio covers explosion‑proof solvent recovery machines and supporting accessories, to handle ethyl acetate, acetone, ethanol, mixed hydrocarbon cleaning agents and many other industrial waste solvents. If your workshop also struggles with waste solvent treatment, welcome to contact us for professional evaluation and quotation.

Unsure whether a solvent recovery machine works for their unique waste stream, they hesitate to place orders. To remove this uncertainty, Chongqing JBETT Environmental Protection Technology Co., Ltd., a professional manufacturer of solvent recovery machines, has completed a full simulated distillation trial on SKH‑410B waste solvent sent by the client. The test setup combined the TE‑60 solvent distillation host and BE‑90 vacuum negative pressure storage unit. The trial strictly replicated real factory operating conditions, not ideal lab environments. The TE‑60 unit features a 60 L feeding capacity, adjustable temperature ranging from 50℃ to 200℃, and supports both 380V power supply. Its theoretical solvent recovery rate reaches up to 95%.  High‑viscosity residue can be discharged easily with our matched high‑temperature filter bags for safer plant operation. Our technical team weighed and sampled the raw feed, and logged all running parameters throughout the cycle, including vacuum level, heating temperature and distillate flow rate at different stages. As temperature rose, clean solvent started to condense and flow out steadily under stable vacuum. Operators fine‑tuned set points dynamically according to material behaviour until distillation was fully completed. For this SKH‑410B test batch: - Inlet net weight of waste solvent: 25 kg- Recovered clean solvent: 21.9 kg- Actual achieved recovery rate: 87.6%A 200ml sample of recovered solvent was retained for further purity testing. Full records of residue condition, tare weight and leftover material were documented. Observed performance, including minor temperature fluctuations and flow changes, was logged to support parameter tuning for the customer’s on‑site commissioning later. Waste organic solvents are classified as hazardous waste. Outsourced disposal is costly, while uncontrolled release creates VOC pollution and compliance risks. Vacuum distillation turns waste solvent back into reusable material. Factories slash recurring hazardous waste charges and reduce fresh solvent procurement, moving toward low‑carbon, circular production. “Most of our overseas customers don’t want to buy based only on datasheets and theoretical numbers. They want proof on their own waste,” said Lyra Lu, International Sales Manager at JBETT. “That is why we offer free sample distillation testing. Real test data removes guesswork and lets clients make confident investment decisions. Every waste solvent behaves differently; a trial before purchase avoids costly mismatches.” Jbett continues optimising distillation workflows for different industrial waste solvents. We deliver stable, customised hazardous waste reduction and solvent recycling solutions for printing, coatings, electronics and chemical manufacturers worldwide.
