What is zero waste?

You’ve likely come across the phrase “reduce, reuse, recycle”—a familiar slogan that has long served as the foundation of sustainability education. But in today’s world of accelerating environmental challenges and resource constraints, both consumers and companies are shifting toward a more ambitious, systemic solution: zero waste.

Rather than focusing solely on waste disposal, the zero waste approach aims to eliminate waste at its source. It’s a systems-based philosophy that reimagines how materials are designed, used, and recirculated, keeping them in use for as long as possible and minimizing environmental impact throughout their lifecycle.

A leading voice in the modern zero waste movement, Béa Johnson, author of Zero Waste Home, introduced a simple yet powerful framework to guide this shift: the 5 Rs:

1. Refuse what you don’t need
2. Reduce what you do use
3. Reuse as much as possible
4. Recycle what can’t be reused
5. Rot (compost) the organic waste that remains

This mindset goes far beyond recycling, it challenges us to redefine our relationship with consumption. For individuals, it can mean living more intentionally. For organizations, it offers a blueprint to redesign operations, optimize resources, and unlock long-term value through sustainability.

How did the zero waste movement begin?

While the term may be relatively recent, the principles behind zero waste have deep roots. For centuries, communities around the world lived with minimal waste repairing clothes, preserving food, reusing tools, and making the most of what was available. Waste became a major problem only with the rise of plastics and mass consumerism in the 20th century.

Key moments in the development of the zero waste movement include:

• 1970s – Paul Palmer: a chemist and founder of the Zero Waste Institute, Palmer coined the term while working to reuse industrial chemicals from tech companies in Silicon Valley.
• 1990s – Daniel Knapp: a sociologist who promoted “Total Recycling” and helped shape municipal-level zero waste planning. His work influenced Australia’s “No Waste by 2010” campaign.
• 2000 – First Zero Waste Conference: held in Kaitaia, New Zealand, it brought together advocates to formalize the movement and spark global action.
• 2003 – Founding of ZWIA: the Zero Waste International Alliance established common principles, definitions, and strategies for organizations pursuing zero waste globally.

Over time, what started as a grassroot effort has grown into a global initiative with businesses, cities, and institutions adopting zero waste initiatives to reduce their environmental footprint and build more resilient systems.

Why does it matter for businesses?

In today’s economy, waste is no longer just an environmental issue, it’s a strategic and financial liability. Businesses operating under the traditional linear model of “take, make, dispose” are increasingly exposed to mounting pressures, rising material and disposal costs, supply chain volatility, stricter environmental regulations, and heightened expectations from sustainability-conscious stakeholders.

Adopting zero waste practices allows companies to move beyond short-term fixes and toward a more resilient, future-ready operating model.

Here’s why it matters now more than ever:

• Cost efficiency and resource optimization: waste is often a symptom of inefficiency. By minimizing unnecessary inputs and maximizing reuse, businesses can significantly reduce operating expenses, from raw materials to logistics to waste disposal.
• Competitive brand positioning: as sustainability becomes a key differentiator in crowded markets, zero waste commitments send a clear message: your company is serious about environmental stewardship, innovation, and long-term value.
  Talent attraction and retention: today’s workforce (especially younger generations) are seeking employers that align with their values. Companies with credible environmental strategies are better positioned to engage and retain top talent who want to make an impact.
• Regulatory resilience: governments around the world are tightening environmental standards and increasing penalties for waste and emissions. A proactive zero waste strategy not only ensures compliance but can also open doors to incentives, certifications, and sustainable procurement opportunities.
• Investor confidence and ESG alignment: investors are now factoring environmental, social, and governance (ESG) metrics into their decision-making. Zero waste contributes directly to measurable ESG performance, reinforcing transparency, accountability, and long-term viability.

In short, zero waste is becoming the new baseline for responsible business. It reflects a shift from reactive environmental compliance to strategic leadership in sustainability, helping organizations reduce risk, uncover new value, and lead with purpose in a rapidly changing world.

Step by step: how can businesses implement zero waste practices

Achieving zero waste doesn’t happen overnight, but it’s possible through strategic planning and consistent action. Here’s a roadmap to guide your organization:

1. Audit your current waste

The first step toward implementing zero waste practices is understanding exactly what waste your organization produces and where it comes from. A comprehensive waste audit allows you to map out the materials flowing through your operations, identify inefficiencies, and set informed, realistic targets for reduction or elimination.

IMD Tip: be sure to audit both front-of-house activities (e.g., offices, retail environments) and back-of-house operations (e.g., warehousing, manufacturing, logistics). The insights from each can vary significantly and both are critical for full visibility.

2. Redesign processes with waste prevention in mind

Once you understand your waste landscape, the next step is reimagining how your business designs and delivers value. Most waste is created not at the end of a process but at the very beginning through design decisions that lock in inefficiencies or disposability.

Shifting to a zero waste model means embedding waste prevention into product, packaging, and process design. This could include:

• Eliminating excess packaging: rethink how goods are shipped and displayed, reducing layers or switching to multi-use containers.
• Designing for modularity and longevity: create products with components that can be easily repaired, replaced, or upgraded, extending lifecycle and usability.
• Choosing sustainable materials: opt for inputs that are recyclable, compostable, or biodegradable, especially in single-use items.
• Integrating design upcycling: use reclaimed or surplus materials in product design to give waste a second life, while also telling a compelling sustainability story.

3. Create a circular supply chain

Transitioning to zero waste requires collaboration that goes beyond internal teams. One of the most impactful steps is to reimagine your supply chain through the lens of circularity, ensuring that every link in the chain supports your sustainability objectives.

Start by partnering with suppliers who are aligned with your environmental goals and open to rethinking traditional models. These partners are essential for embedding zero waste principles throughout your operations.

Work together to implement take-back or reuse programs such as returning pallets, containers, or packaging so materials can be reintegrated rather than discarded. This helps reduce waste and optimize logistics.

You can also explore closed-loop systems, where materials are continuously recovered, refurbished, or repurposed to serve new functions. In this model, waste becomes a valuable input. Products are designed so their components can be disassembled, repaired, or recycled into new items, keeping them in circulation and out of landfills. Beyond environmental benefits, closed-loop systems can help reduce costs, build supply chain resilience, and support long-term sustainability goals.

Finally, prioritize vendors that offer recycled or upcycled alternatives to virgin materials. These choices not only shrink your environmental footprint but also signal your commitment to responsible sourcing.

4. Educate and engage your workforce

A zero waste strategy cannot succeed without buy-in and participation from your employees. Sustainability efforts thrive when teams are informed, engaged, and motivated to take ownership of everyday actions.

Start by:

• Offering training and workshops that explain the why and how of zero waste.
• Creating clear, accessible systems for waste separation, material return, and reporting.
• Recognizing and rewarding sustainable behaviors, whether through formal programs or informal leadership.

When people understand the impact of their actions and see that sustainability is embedded in company culture, they’re more likely to support change—and become advocates for it.

5. Measure progress and iterate

Zero waste is an ongoing transformation. To maintain momentum and credibility, businesses need to measure progress with clear, actionable metrics.

Define and monitor KPIs such as:

• Percentage reduction in landfill-bound waste;
• Recycling and composting rates;
• Financial savings from waste prevention and materials reuse;
• Supplier compliance with circular practices.

Review these metrics regularly (ideally quarterly) and communicate results transparently. This not only builds internal accountability but also strengthens external trust among customers, partners, and investors.

A culture of measurement and iteration ensures that your zero waste strategy evolves with your business and continues to deliver value over time.

What’s the difference between zero waste and low waste?

As organizations begin to explore sustainability strategies, it’s common to encounter terms like zero waste and low waste (sometimes even “no waste” used interchangeably). But while the intent behind them is similar, zero waste and low waste reflect different levels of commitment and operational scope. Clarifying the difference is essential for setting clear internal goals, communicating with stakeholders, and measuring progress effectively.

The table below outlines the core differences between these two main approaches to waste reduction:

For many businesses, a low waste strategy is a practical starting point, especially in complex supply chains or heavily regulated industries. Over time, these efforts can evolve into more ambitious zero waste initiatives, laying the foundation for long-term transformation and leadership in circular economy practices.

Examples of zero waste companies leading the way

Several organizations across industries have embedded zero waste principles into their core strategy, not just as a sustainability initiative, but as a driver of long-term value. Their efforts illustrate how reducing waste can fuel innovation, strengthen brand loyalty, and unlock operational efficiencies.

• Patagonia has long been a pioneer in circular design, incorporating repair, resale, and product take-back programs to extend the life of its gear and reduce material waste.
• IKEA has committed to becoming a fully circular business by 2030. This includes redesigning products for reuse, recycling, and regeneration, as well as piloting furniture rental and refurbishment services.
• Googlehas achieved zero waste to landfill in multiple data centers by leveraging smart waste management systems and integrating circular practices across its operations and supply chains.

These companies prove that zero waste is more than an environmental ambition, it’s a strategic differentiator that positions brands for resilience, relevance, and profitability in a resource-constrained world.

What are the challenges and limitations of zero waste?

With so many clear benefits (such as cost savings, brand differentiation and reduced emissions) it might seem like adopting zero waste practices would be an obvious choice. Yet in practice, both individuals and organizations often encounter significant hurdles when trying to implement these strategies at scale.

Short-term costs and operational disruption

One of the most immediate barriers is the upfront investment required to transition from linear to circular systems. Redesigning products, modifying packaging, updating infrastructure, or shifting to reusable logistics all involve costs—especially for large, complex operations or legacy systems.

Resistance to change and cultural inertia

Introducing a zero waste model often means rethinking long-established processes. This can generate resistance among employees, suppliers, or customers who are used to the convenience of single-use items or traditional procurement cycles. Without sustained internal engagement, even well-intentioned strategies may stall.

Infrastructure and supply chain limitations

Many regions still lack reliable composting, recycling, or refill infrastructure, making it difficult to implement circular models across all locations. Additionally, coordinating zero waste practices across global supply chains adds complexity, especially when policies, capabilities, and cultural norms vary by country or vendor.

Industry-specific and material constraints

In certain sectors, such as healthcare, food, or heavy manufacturing, some level of waste is currently unavoidable due to hygiene, safety, or technical standards. Likewise, some materials (like composite plastics or industrial by-products) still lack scalable reuse or recycling solutions, limiting full circularity in the short term.

Issues of accessibility and equity

Zero waste is not equally feasible in all contexts. For individuals and communities with limited access to sustainable products or fresh food, zero waste living may be prohibitively expensive or simply unavailable. Businesses in these regions face similar challenges, often lacking the resources to invest in the infrastructure or partnerships needed to make meaningful changes.

Make zero waste your competitive advantage

Zero waste is no longer a nice-to-have: it’s a business imperative. As pressure mounts from consumers, regulators, and supply chain disruptions, companies that redesign their operations around circular principles are better positioned to lead with efficiency, resilience, and purpose.
