Allow the waste oil to settle so that impurities descend and separate. Place the waste oil that has undergone sedimentation to remove precipitates into a distillation flask, set up the distillation apparatus, and heat for atmospheric distillation. Industrially, use an oil filter machine for filtration.

Disposing of waste hydraulic oil must never be done carelessly, as it is harmful to both the environment and health. Hydraulic oil contains chemicals, and improper disposal can contaminate groundwater and may have long-term effects on the health of our community. I always collect it in clean, sealed containers, such as old water bottles or plastic buckets, ensuring the lids are tightly closed. Then, I take it to a nearby auto repair shop or municipal recycling center. Many places offer free recycling services, making it both convenient and eco-friendly. By participating in these actions, I can feel the impact of protecting the Earth, as small daily efforts add up over time. Remember, never pour it down the drain or into the trash bin—regulations require proper disposal to avoid fines. Additionally, by reducing oil usage, such as choosing high-quality brands that extend oil life, we can also minimize the amount of waste oil produced.

When changing oil, I usually prepare an oil drain pan and buckets. Don't waste the used hydraulic oil—store it in leak-proof containers and seal them. Then check local recycling points or contact a 4S shop for disposal. After recycling, it can be reused, reducing resource waste. For safety, wear gloves during the operation, as oil contact with skin is harmful. It's essential to understand local environmental regulations, as many cities have dedicated collection sites. I recommend everyone learn this simple process—environmental protection starts with details. Recycling hydraulic oil also saves money, killing two birds with one stone. Simple tools like funnels can prevent spills, ensuring a clean process throughout.

Every time I change the hydraulic oil, I pour the used oil into old bottles, tighten the caps, and store them in the garage. When I have time, I drop them off at the repair shop—they have recycling bins. Never pour it by the roadside or down the drain, as it can cause serious problems. It's an easy and convenient operation that protects the environment and gives peace of mind.

From a safety perspective, improper disposal of waste hydraulic oil poses significant risks. It is a pollutant that can contaminate water sources if it seeps into the soil and may also lead to health hazards such as skin irritation. I emphasize storing it in sealed containers and keeping it out of reach of children. It must be sent to an authorized recycling center for proper disposal, as failure to do so may cause fire hazards. Ensure to wear protective gloves during collection, and in case of leakage, use sand or cloth to absorb it. Local regulations require compliance, so don't cut corners to save costs.

Disposing of waste hydraulic oil is part of routine maintenance. Collect and seal it before sending it to a recycling point. I regularly check the oil level and opt for long-life hydraulic oil to reduce the frequency of changes. Combining prevention measures to minimize waste oil production is more environmentally friendly. Always wear gloves for safety during operations, and contact authorized agencies for easy completion. This way, you protect your vehicle and maintain nature.
