Exhaust emission:

Source: In the heating process such as extrusion and blow molding, LDPE resin and added additives may volatilize due to heat to produce organic waste gas, such as hydrocarbons.

Impact: If these exhaust gases are directly discharged into the atmosphere, it will cause air pollution, and some of the components of them may participate in photochemical reactions, forming pollutants such as ozone, endangering human health and the ecological environment.

Countermeasures: An effective waste gas collection system should be equipped, such as a collection hood set above the extruder, blow molding machine and other equipment, and the waste gas is collected and purified by activated carbon adsorption, catalytic combustion and other waste gas treatment equipment, and then discharged after reaching the standard.

Wastewater treatment:

Source: The cooling process of production equipment will produce a large amount of wastewater, which may pollute the water environment if discharged directly. In addition, if there is cleaning equipment, sites and other operations in the production process, it will also produce waste water containing pollutants such as plastic particles and auxiliaries.

Impact: May lead to water eutrophication, affect the survival of aquatic organisms, may also pollute groundwater, affect the surrounding water environment and ecological balance.

Countermeasures: The construction of special wastewater treatment facilities, the use of physical precipitation, chemical oxidation, biodegradation and other processes to treat the wastewater, so that it meets the corresponding discharge standards and then discharged into the municipal sewage network or natural water bodies.

Energy consumption:

The production of LDPE plastic bags consumes a lot of energy, which is mainly used for heating extruders, blow molding machines and other equipment, as well as driving various power equipment such as motors.

Impact: Excessive consumption of energy will not only increase production costs, but also exacerbate energy shortages. At the same time, most of the energy production process will also have a certain impact on the environment, such as carbon emissions.

Countermeasures: The production process and equipment selection can be optimized, and energy-saving extruders, blow molding machines and other equipment can be used to improve energy efficiency. Renewable energy sources such as solar and wind energy can also be used to meet part of the energy demand and reduce the dependence on traditional energy sources.

Solid Waste Management:

Source: Some solid waste will be generated in the production process, such as discarded LDPE resin raw materials, unqualified plastic bag products, scraps and waste activated carbon generated in the waste gas treatment process.

Impact: If these solid wastes are discarded or disposed of improperly, they will occupy a large amount of land resources, and may also cause pollution to soil and water bodies, affecting the surrounding ecological environment.

Countermeasures: Collect and recycle solid waste, such as waste LDPE resin and scraps, and reuse them for production; For the waste that cannot be recycled, it should be properly disposed of in accordance with relevant regulations, such as sending it to landfill or incineration plant for treatment, but pay attention to preventing secondary pollution.

Noise control:

Source: During the production process, the extruder, blow molding machine, fan and other equipment will produce large noise during operation, which will affect the surrounding environment and the health of the operator.

Impact: Long-term exposure to high noise levels can lead to health problems such as hearing loss and cardiovascular disease, as well as affecting the quality of life of nearby residents.

Countermeasures: Take effective sound insulation and noise reduction measures, such as installing shock pads and mufflers on equipment, and setting sound barriers in the workshop to reduce the spread and impact of noise.

Recyclability and environmental friendliness of the product:

Consideration: Although LDPE plastic bags themselves have a certain degree of recyclability, but in the production process should also be fully considered how to improve its recycling rate and environmental friendliness.

Countermeasures: In the product design stage, the thickness and weight of plastic bags can be reduced as much as possible to reduce the use of raw materials; At the same time, recyclable signs are marked on plastic bags to improve consumers' awareness of recycling and facilitate recycling. In addition, more degradable or biodegradable additives can also be developed and used to improve the degradation rate of plastic bags in the natural environment and reduce the long-term impact on the environment.Exhaust emission:
