Less waste, more value: the case for upstream circular solutions

‘Reduce, reuse, recycle’ is a widely recognized slogan of the circular economy. But those terms carry immensely different weights for firms and investors. We explain why recycling is a circular solution of last resort, while broadening to upstream solutions can help produce better outcomes for the environment and portfolios.

Summary

  1. Recycling and waste collection are low-value solutions
  2. Upstream solutions generate more value, eliminating waste before it starts
  3. Broader circular scope, boosts resource efficiency and return potential

Though recycling is important, it was never intended to be the poster child of the circular economy. That’s because it is insufficient and inefficient compared to upstream solutions that prevent waste from being created in the first place. In fact, the EU Commission, the globe’s foremost leader in driving circularity, underscored its preference for upstream solutions when it acknowledged that 80% of environmental impacts result from decisions made at the design stage of product development. 1

In a perfectly circular economy, recycling would be used sparingly if at all

Recycling – an inadequate solution

The share of recycled materials used in the global economy now sits at around 7% and continues to fall.2 That means that the overwhelming majority of material stock introduced into the economy each year is from new inputs.

To be sure, regulatory action requiring greater recycled content and industry innovation in recycling technologies are boosting recycling’s impact and growing its deployment in absolute terms. But it’s simply not enough to keep pace with accelerating rates of production. Over the past five decades, the total volume of material produced annually has grown nearly threefold (270%).3 Without a significant slump in demand, it’s unlikely that recycling will ever catch up.

Recycling is a costly, low-value solution. For many industries, recycling and recovery costs – collection, sorting, cleaning and refining – are too high. For example, recycled broken or waste glass can be up to 20% more costly than virgin materials.4 In the US, the premium for recycled plastic over new polymers and resins has reached 25%.5 That’s a margin breaker given only 1% to 7% of consumers are willing to pay a premium for recycled content. 6

And processing costs are increasing as material mixes in waste streams become more sophisticated. The marginal value yield of multi-polymer plastics, mixed-fiber textiles, or multi-component electronics and machinery is much lower than for simpler materials such as glass or aluminum.7 In addition, recycled content is often lower quality and less functional, further limiting potential use cases and commercial value.

Figure 2 – Recycled plastic cost more in than virgin (Europe)

The graphic shows pricing spreads between two recycled PET plastic grades (Food-Grade pellets and Clear Flakes) and virgin PET plastic in Europe. Recycled plastics are significantly more expensive. In May, Food-Grade Pellets were priced EUR 700 / metric ton and EUR 400 higher than virgin PET pellets. Food-Grade pellets are processed according to stricter quality standards and can be used for things like food or medication packaging. Clear Flakes are used as feedstock for industrial applications with less stringent quality criteria.

The power of upstream thinking

According to circular experts, waste and pollution are the result of flawed design.8 In a perfectly circular economy, recycling would be used sparingly if at all. Circular solutions are best applied upstream at the product’s original conception rather than at the end of a product’s life. That means designing products that are durable, repairable, modular, and biodegradable.9 It also includes companies whose innovative technologies enable their customers to use resources smarter so they can achieve more with less.

Building on this principle, the Circular Economy Equities strategy (the Strategy) maintains a tilt toward companies that are enabling or applying higher-value, upstream solutions. That significantly enlarges the opportunity set from a narrow focus on waste and recycling stocks to a broad basket of sectors and industries.

Examples of the Strategy’s broad sector exposure

  • Technology and Industrials – Though servicing vastly different industries, Cloudflare and Ashtead Group both promote circularity through shared platforms that replace on-premise asset ownership with on-demand access. Cloudflare leases cloud computing and network infrastructure to remote locations, eliminating the need for individual companies to build their own data centers.

    Ashtead Group rents industrial equipment, from scaffolding and manlifts to conveyor belts and power tools. Product sharing models increase asset utilization rates and product longevity via centralized maintenance. More importantly, they enable an economy to get more done with fewer resources, decreasing the need the physical assets deployed across the economy.

  • Manufacturing and Construction – Celestica and Cavco are two standouts that provide shared manufacturing services to multiple industries. Cavco focuses on prefabricated stationary homes, where scaled and streamlined in-factory manufacturing and assembly significantly reduces the excess material waste of onsite construction.
    Celestica provides shared manufacturing of electrical components for customers across aerospace and energy systems to medical devices and diagnostic equipment. Strict manufacturing efficiency and tighter control over supply chain logistics help reduce resource use. Modular design encourages product refurbishments and repairs that extend product life.

  • Consumer Staples and Materials – Moving closer to consumer goods, Sprouts Farmers and Sensient are good illustrations of the circular solutions in the food and agricultural sector. Sprouts is a supermarket focused on fresh, organic, and locally grown produce. Less packaging, chemical preservatives, and transport emissions translates to lower emissions and environmental footprint compared to processed food or meat alternatives.
    Sensient focuses on supplying customers in the food, cosmetics and pharmaceuticals sectors with colors, flavors and specialty ingredients that are naturally regenerative, derived from plants and biological sources.

  • Healthcare and Environmental Services – Halma and Galenica illustrate how circular solutions are being applied into health and environmental services. Halma develops technologies for safety, health and environmental monitoring – from clean water sensors to fire detection systems – that prevent risks and extend the useful life of assets. Galenica, through its pharmacy network and logistics operations, improves access to medicines while reducing inefficiencies and waste in healthcare delivery.


Broad style exposure

Too much focus on downstream recycling and waste management providers narrows the investment universe and limits exposure to attractive opportunities across industry value chains. Broadening the scope to upstream solution providers not only expands the portfolio’s return potential but also diversifies the portfolio’s exposure to different style factors including high-growth innovation, high-quality compounding cyclicals and defensive stalwarts (see Figure 3).

By moving away from recycling toward upstream solutions, the strategy can tap into a diverse range of industries and companies with compelling business models and growing market share. Not only does this strengthens the portfolio’s potential to generate sustainable returns, it also enables it to invest in companies generating higher- value circularity and environmental impact.
