Air Compressors for Recycling Plants

J Ll Leach is supporting UK recycling plants with reliable Atlas Copco air compressors, supplied and installed from our Stoke, Birmingham and Shrewsbury branches.

Compressed air is a vital utility for recycling plants, used for sorting, conveying, compacting, and many other applications.

Together with electricity and water, compressed air plays the role of the “fourth utility” behind the essential processes that keep your plant productive and profitable. The right robust and efficient compressed air systems for recycling plants are a strategic asset; an interruption will bring your multi-million-pound operation to a grinding halt.

This guide will show you how reliable compressed air keeps your plant’s critical processes running, share solutions to some common operational and environmental challenges, and demonstrate how working with a specialist like J Ll Leach will make your plant more reliable, lower your energy bills, and make compliance easier.

The Role of Compressed Air in Your Recycling Operations

Clean, dry compressed air in recycling is integral to the material recovery process at nearly every stage. From sorting to baling, air is a critical component and demands custom solutions to meet each step in the process and every material stream in a modern Material Recovery Facility (MRF).

Automated Sorting: Your high-speed optical sorters and laser-guided sorting equipment are only as fast and effective as the air supply that ejects materials into rejection streams. High-speed air valves must fire in milliseconds to separate valuable recyclates from waste.
Material Handling: Pneumatic conveying systems use compressed air to convey sorted materials through a closed system of pipes, minimising dust and lost materials in your operation. Low-pressure blowers, such as the Atlas Copco ZS series, are often the most efficient choice here.
Baling and Compaction: Large industrial pneumatic balers use pneumatic-hydraulic systems to compress materials into dense, easily stored and transported blocks.
Dust Collection: Pulse-jet baghouses utilise compressed air to clean filters, ensuring consistent air quality and compliance with environmental regulations.
Wastewater Treatment: Low-pressure blowers supply the aeration required for biological treatment processes, a critical component of environmental compliance.

Solving the Toughest Operational Challenges in Your Plant

Industrial environments for waste management facilities are some of the most challenging for machinery. To combat the persistent and high levels of contamination, dust, and energy costs, a purpose-designed heavy-duty compressed air system is vital.

The Challenge: Contamination from Moisture and Oil

Water vapour is present in all atmospheric air. When compressed, this vapour condenses into moisture. A single 100kW compressor can generate 85 litres of contaminated water in an eight-hour shift. If this liquid is allowed to enter your system, it will corrode pipework and contaminate the sensitive optics on your sorting machines, which can cost over £8,000 to replace per component.

The Solution: Multi-Stage Air Treatment

A complete multi-stage air treatment concept is a must. High-performance dryers and filters keep your equipment safe. Your most critical applications are supported by an Atlas Copco oil-free ISO 8573-1 Class 0 compressor, which delivers oil-free air with certification. You have total control over air purity, with zero risk of contamination, an oil-water separator processes all your condensate. Safe condensate disposal is a legal obligation.

The Challenge: Dust and Debris

The dusty environment of a UK recycling plant is a constant threat to your machinery. Airborne particulates clog compressor coolers and filters, leading to overheating, reduced efficiency, and a significantly higher risk of unexpected equipment failure.

The Solution: Weatherproof Enclosures

The ideal solution is to extract the equipment from the hostile environment. J Ll Leach can design and install custom, weatherproof enclosures for your entire air compressor system (such as the Atlas Copco AIRCUBE). This protective enclosure will create a clean, temperature-regulated environment that isolates your equipment from airborne dust and debris, ensuring maximum performance and longevity of your investment.

Unlock Energy Efficiency with VSD Technology and SMARTLINK Monitoring

Efficient air compression generation is a significant operational expense. It can often account for up to 40% of your plant’s total electricity bill, and in unmanaged systems, it’s estimated that up to 50% of the compressed air generated is wasted. Optimising this can significantly boost your profitability.

Variable Speed Drive (VSD) Compressors

Air demand in your waste processing plant fluctuates constantly. Atlas Copco VSD compressors, such as the market-leading GA VSD⁺ rotary screw compressor series, automatically adjust their motor speed to match air demand precisely. This eliminates wasteful unloaded running, helping you reduce energy costs by up to 50%.

Heat Recovery

Over 80% of the electrical energy used by an air compressor is converted into heat. Instead of wasting it, heat recovery systems can capture up to 94% of this energy to generate hot water for your facility ideal for washing lines or space heating.

This converts a waste byproduct into a valuable resource and also helps reduce air compressor running costs.

System Audits and Monitoring

The first step to eliminating waste is identifying it. A comprehensive energy audit utilises ultrasonic identification technology for identifying costly air leaks and analytics to map your system’s performance. You can combine this with Atlas Copco’s SMARTLINK remote monitoring platform.

It provides real-time performance alerts and predictive maintenance insights, giving you the data to optimise performance, improve uptime, and prevent downtime in your operations.

Ensuring Your Legal and Environmental Compliance

Operating a pressure system in the UK carries significant legal responsibilities. A specialist partner can ensure your facility remains safe and fully compliant with all relevant regulations, avoiding the heavy penalties of non-compliance.

Pressure Systems Safety Regulations 2000 (PSSR): This is a legal requirement to prevent serious injury. Regulatory compliance requires having a Written Scheme of Examination (WSE) for your system, which a competent person must draw up.
Air Quality and Energy Standards: Your operations must meet ISO 8573-1:2010 for air purity and should align with WRAP energy benchmarks.
Environmental Discharge: The oily condensate produced by a compressor cannot be discharged into the drain as it is classified as hazardous waste. It must be processed to prevent ecological harm and legal penalties.

Frequently Asked Questions

What is the best air compressor for a recycling plant?

For most UK recycling plants, an oil-injected rotary screw compressor with Variable Speed Drive (VSD), such as the Atlas Copco GA VSD+, is the standard choice due to its ability to handle fluctuating demand. However, for optical sorting lines where air purity is critical, we recommend Class 0 oil-free compressors to protect sensitive lenses.

How does compressed air quality affect optical sorting?

Optical sorting relies on precise air valves to eject materials. If the air contains oil or moisture, it can cause valves to stick or fog up the optical sensors. This leads to missed sorts, lower yield, and expensive damage to the sorting units.

Can I reduce the energy cost of my current air system?

Yes. Switching to VSD compressors, fixing leaks, and installing heat recovery systems are the most effective ways to lower bills. Additionally, under the UK government’s ‘Full Expensing’ scheme, you may be able to claim 100% first-year capital allowances on new, energy-efficient plant machinery.
