From Plastic to Plant-Based: How to Make the Switch to Compostable Deli Packaging

As sustainability expectations rise across Aotearoa, more food businesses are rethinking their packaging. Making the switch from plastic to compostable deli containers isn't just an eco-friendly upgrade — it’s a smart move for future-proofing your business. In this guide, we show how New Zealand cafes, delis, and food retailers can transition smoothly to compostable packaging without compromising on quality or customer experience.

Why Switch from Plastic to Compostable?

Plastic deli containers, made from fossil fuels, contribute heavily to landfill waste and environmental pollution. In contrast, compostable alternatives like PLA (polylactic acid) and sugarcane pulp are made from renewable resources and designed to break down under commercial composting conditions.

In 2022, New Zealand began phasing out hard-to-recycle plastics under the Ministry for the Environment’s waste reduction roadmap. Compostable containers align perfectly with this shift, offering an opportunity for food businesses to stay compliant while showing customers their commitment to the planet.

The New Zealand Ministry for the Environment has also highlighted the growing role of compostable packaging in its position statement, acknowledging that while compostable products are not a silver bullet, they can play a supporting role in a circular economy when used appropriately. This makes it even more vital for Kiwi businesses to understand the environmental impact and proper use of compostable deli containers.

Step-by-Step: How to Make the Switch

1. Audit Your Current Packaging

Take stock of the plastic packaging you're currently using. Which items can be replaced with compostable versions — deli containers, lids, cutlery, trays?

2. Choose the Right Compostable Materials

Popular plant-based materials include:

• PLA (Bioplastic): Great for cold foods and clear presentation.

• Bagasse (Sugarcane Pulp): Ideal for hot or oily foods, sturdy and microwave-safe.

• Paperboard with Compostable Lining: Good for dry goods or baked items.

Ensure products are certified compostable to recognised standards such as EN13432 or ASTM D6400.

3. Educate Your Team

Train staff on identifying compostable packaging, how to store it correctly, and how to communicate its benefits to customers.

4. Communicate with Customers

Add signage or menu mentions like “Now using 100% compostable containers”. This builds trust and encourages more sustainable customer behaviour.

5. Plan for Compostable Waste Disposal

Partner with a commercial composting service where available, or guide customers on how to dispose of compostable packaging correctly.
