Green construction is a basic requirement of modern building engineering, and construction waste chutes must meet environmental compliance requirements. Longkang HDPE chutes meet relevant standards in dust, noise, waste, and material environmental aspects. This article details the environmental compliance parameters.
- Fugitive Dust Control Compliance
- Applicable Standards
- Integrated Emission Standard of Air Pollutants, GB 16297
- Fugitive dust control requirements of the Green Construction Guidelines
- Local construction dust management regulations
- PM10 concentration limit: at site boundary ≤150μg/m³
- Longkang Chute Dust Control
- Enclosed chute conveying reduces fugitive dust
- Joint sealing rings prevent dust leakage
- Sealed feed inlet door
- Enclosed bottom collection
- Reduces fugitive dust by over 80% compared with open lifting
- Optional Upgrades
- Negative-pressure dust extraction port
- Spray dust suppression at the feed inlet
- Sealed collection hopper plus dust extraction
- Meets strict environmental requirements
- Noise Control Compliance
- Applicable Standards
- Emission Standard for Environmental Noise at Construction Site Boundary, GB 12523
- Daytime (6:00-22:00): ≤70dB
- Nighttime (22:00-6:00): ≤55dB
- Measurement point: 1m outside the site boundary, at 1.2m height
- Longkang Chute Noise
- HDPE material noise reduction of 15–20 dB
- 500mm chute noise about 60–70 dB (at 1m distance)
- At a site boundary distance of 10m or more, daytime requirements are met
- Night construction requires a noise reduction upgrade option
- Noise Reduction Upgrade
- Pipe wrapped with sound-absorbing cotton (25mm)
- Can further reduce by 5–10 dB
- Meets night construction noise requirements
III. Material Environmental Compliance
- Environmentally Friendly Raw Materials
- HDPE is non-toxic and odorless
- Complies with GB 4806.7 food contact material standard
- Contains no toxic plasticizers
- Contains no heavy metals
- Recyclable
- HDPE is 100% recyclable
- Can be pelletized and recycled after end of life
- Generates no solid waste
- Meets circular economy requirements
- No Secondary Pollution
- The chute releases no harmful substances
- No leachate pollution upon contact with rainwater
- Does not corrode or rust
- Produces no rust water pollution
- Waste Disposal Compliance
- After Chute End of Life
- Longkang product service life is 5–8 years
- After end of life:
- Can be returned to Longkang for recycling
- Or sorted and treated as plastic waste
- Generates no hazardous waste
- Wearable Parts Disposal
- Sealing rings: rubber parts, recyclable
- Buckles: metal parts, recyclable
- No hazardous waste
- Green Construction Evaluation
Longkang chutes contribute to green construction evaluation:
- Environmental protection: dust control, noise control
- Material saving: reusable, saves materials
- Energy saving: no energy consumption (passive)
- Water saving: optional wet dust suppression
- Green construction demonstration project: bonus item
- Regional Compliance Requirements
- General Regions
- Meeting GB standards is sufficient
- Standard configuration
- Key Cities (Beijing, Shanghai, etc.)
- Strict dust control
- Enclosed chute plus dust extraction required
- Upgrade configuration recommended
- Sensitive Zones (near schools, hospitals)
- Strict noise requirements
- Noise reduction wrapping required
- Special scheme required for night construction
- Coastal Regions
- Salt spray corrosion
- Stainless steel buckles recommended
- HDPE is salt-spray resistant
VII. Environmental Compliance Documents
Longkang can provide:
- Product material environmental statement
- HDPE raw material test report
- Noise test data
- Dust control plan
- Green construction application cases
VIII. Longkang Environmental Commitment
- Uses virgin HDPE, no recycled material
- Product is non-toxic and odorless
- Recyclable and reusable
- Helps clients pass green construction acceptance
- Continuously
improve environmental performance
