Most conversations about “eco-friendly packaging” start and end with materials: recyclable films, compostable trays, lighter bottles. Those choices matter, but they are only one part of the picture. If your line scrapes product, wastes film, or burns excess power every shift, you are leaving the biggest sustainability gains on the table. Let’s Look at sustainable packaging equipment and all that entails.
A more productive approach is to look at the whole system — process, equipment, and materials working together. For New Zealand food and beverage manufacturers, that is where Advanced Packaging Systems (APS) and its global equipment partners can make a substantial difference: reducing product waste, lowering energy consumption per tonne, and equipping lines to run the next generation of sustainable packaging formats.
This article sets out a practical, equipment-grounded framework for building a greener processing and packaging operation — and explains which APS partners can help at each stage.

Three pillars of a more sustainable processing and packaging line
Practical packaging-line sustainability can be structured around three distinct areas:
- Product and process yield — less waste, fewer off-spec batches.
- Energy and runtime efficiency — lower kWh per tonne and fewer unplanned stops.
- Packaging material flexibility — lightweight, recyclable, and right-sized pack formats that your equipment can reliably run.
When you use this lens, “green packaging” stops being a materials specification and becomes an operational strategy — one that is tightly aligned with OEE targets and capital expenditure decisions.
1. Product and process yield: the greenest pack is the one you don’t waste
Every kilogram of product sent to waste has already consumed ingredients, energy, water, labour, and packaging. Improving yield is one of the fastest and least controversial ways to cut both cost and environmental impact simultaneously.
Sieving and filtration: Russell Finex
Russell Finex high-performance sieving and filtration equipment removes foreign bodies and oversize particles before product reaches fillers or baggers. This reduces contaminated and off-spec batches, limits the frequency of line flushes, and improves right-first-time production rates. For facilities handling powders, liquids, or slurries, upgrading the sieving and screening step is one of the clearest yield improvement opportunities available.
High-shear mixing: Silverson
Silverson high-shear mixers deliver consistent, repeatable dispersion and emulsification — reducing formulation variability and the incidence of batches falling outside specification. Better mixing translates directly into fewer rework cycles and a more stable downstream packaging process. This is particularly relevant for food, dairy, pharmaceutical, and cosmetic manufacturers where batch-to-batch consistency is a compliance requirement as much as a quality one.
Powder handling: Hanningfield and Dinnissen
Enclosed transfer systems, accurate dosing, and gentle product handling from Hanningfield and Dinnissen reduce dust, spillage, and waste across powder and granule lines. That improves yield, supports a cleaner working environment, and can contribute directly to operator health and safety outcomes — all from a single capital upgrade.
For plant managers, these improvements connect to metrics already tracked: yield percentage, rework rate, and product loss per batch. Mapping those numbers against specific equipment upgrades makes sustainability a line item in cost-of-goods and OEE reporting — not a separate initiative.
Example: A dry-blend facility upgrades to enclosed powder transfer and finer sieving before packaging. Product-on-floor drops, dust complaints fall, and giveaway is reduced. The business case comes first; the sustainability outcome — less wasted product, fewer wasted packs — follows directly from the same project.

2. Energy and runtime efficiency: reducing kilowatt-hours per tonne
Energy prices, retailer decarbonisation requirements, and sector-level emissions targets are all driving New Zealand food manufacturers to improve energy productivity. Many lines still leak energy through inefficient product movement, excessive stop-start cycling, and suboptimal freezer or thermal process control.
Spiral freezer conveyor belts: Ashworth
Ashworth spiral freezer belts are engineered for consistent product support, precise dwell time control, and efficient airflow management within spiral freezer systems. A well-specified belt reduces the energy required per tonne of frozen product, limits product damage, and extends cleaning intervals — all of which contribute to lower operating costs and a reduced energy footprint per unit of output.
Wire mesh conveyor systems: Wire Belt
Wire Belt stainless steel conveyor belts keep product moving smoothly across processing and packaging operations. Efficient conveying with minimal bottlenecks and blockages reduces unplanned stops and restarts — a significant hidden source of wasted energy and lost production time. Wire Belt’s open-mesh designs facilitate drainage, airflow, and cleaning, reducing water and chemical use in food-grade environments.
End-of-line automation: palletisers and case handling
APS palletising and case-handling solutions maintain a steady, predictable product flow from the packaging line to the pallet. Consistent end-of-line throughput allows upstream equipment to run at optimised speeds without creating accumulation-driven stops — reducing both power consumption and product damage in the final stages of the line.
Example: A ready-meal plant replaces older spiral belts and rationalises its conveying layout. The line runs more consistently at target speed, restarts are reduced, and energy per tray drops. That is an energy-efficiency project that also advances the site’s sustainability targets.

3. Packaging material flexibility: running recyclable and lightweight formats
Sustainable packaging materials are where most brand teams begin their sustainability discussion — and where many plants encounter hard operational reality. Films that are technically recyclable often behave differently on machines designed for older laminates. Lightweight bottles and closures can expose weaknesses in unscrambling, capping, or labelling.
VFFS systems for mono-material films: VH Vertical Packaging
VH Vertical Packaging VFFS systems combine robust mechanical engineering with precise film handling and advanced sealing control. That makes them well suited to running thinner gauges, mono-material films — such as recyclable PE or PP structures — and emerging eco-substrates, while maintaining target line speeds and seal integrity. For brands exploring recyclable or compostable flexible films, the ability to fine-tune sealing temperature, dwell time, and web tension is essential to keeping scrap rates under control.
Secondary packaging: right-sizing cartons and cases
Cartoning and case-packing systems supplied by APS support right-sizing of secondary packaging and more efficient case-fill patterns. By matching pack counts, case dimensions, and pallet configurations more closely to product geometry, you reduce corrugate use and void space — and improve pallet utilisation and transport efficiency. These are environmental gains that simultaneously reduce packaging cost and improve logistics productivity.
Bottle handling for lightweight formats
For beverage, dairy, and sauce manufacturers, equipment that can reliably handle lightweight bottles and closures without compromising line stability is a prerequisite for material reduction. Accurate, consistent labelling also supports recyclability at end of life: label choices that interfere with sorting or washing processes can undermine a recyclability claim made elsewhere in the supply chain.
Example: A snack brand moves from a traditional laminate to a recyclable mono-material film. Working with APS and VH Vertical Packaging, they trial the new film on a VFFS system with adjusted sealing temperatures and dwell times. Scrap stays within tolerance, pack integrity is maintained, and the brand can make a credible recyclability claim without adding another line.

Building a pragmatic sustainability roadmap with APS
Thought leadership is useful; a structured plan of action is better. Using the three pillars above, you can build a 12–24 month roadmap for capital investment, with APS as a partner across the whole value chain.
- Diagnose where your largest environmental ‘leaks’ are today.
- High product waste or rework? Prioritise process solutions: Russell Finex sieving, Silverson mixing, or enclosed powder handling from Hanningfield or Dinnissen.
- Rising energy costs and unstable throughput? Assess conveying and freezer efficiency — including Ashworth spiral belt upgrades, Wire Belt conveying improvements, and end-of-line automation.
- Pressure to change packaging materials? Review your VH Vertical Packaging VFFS capability and assess secondary packaging right-sizing options.
- Think in systems, not individual machines.
- Yield projects benefit from reviewing the full path from ingredient intake to filler or weigher.
- Energy projects should cover how product moves across all thermal steps, conveyors, and accumulation points — not just a single freezer or oven.
- Material flexibility projects need to consider primary, secondary, and tertiary packaging together: bag, carton, case, and pallet.
- Report sustainability metrics alongside operational and financial ones.
- For each project, quantify both the operational return (waste reduction, throughput, maintenance) and the environmental outcome (kWh per tonne, waste avoided, packaging weight per unit).
- This creates a business case that finance, operations, and marketing can all support — and that can be communicated credibly to retailers and end-customers.
By structuring your next round of capital decisions around yield, energy, and material flexibility — and by working with a partner like APS that spans processing and packaging — you create a framework that is both strategically credible and operationally grounded. It allows you to talk confidently about sustainable packaging equipment without overpromising on what any single material or machine can do in isolation.
Contact APS to discuss how these equipment families can be applied to your specific process and packaging configuration.
