Reverse logistics and sustainability in Brazil: when returns actually cut impact

Reverse logistics and sustainability meet when a returned product gets a second life: it is resold, repaired or recycled instead of heading to landfill. For companies selling from or into Brazil, the environmental gain is not automatic. Every return adds a transport leg, and only measurement shows whether it avoided more impact than it created.

The concept and the types of reverse flow are covered in What is reverse logistics?. This guide deals with the environmental math: what Brazilian law requires, what Europe started to demand in 2026 from anyone selling there, and which numbers make a sustainability report stand up to an audit.

Is reverse logistics sustainable by definition?

No. A well-meant return can cost the planet more than the product is worth. Picture a R$ 60 T-shirt sold from São Paulo to a customer in Lisbon and sent back because the size was wrong. It crosses the Atlantic twice, and if it arrives creased and without its tag, it may end up in the same bin it would have reached in Portugal.

Brazil's own waste law gives you the yardstick. Article 9 of Law No. 12,305/2010, the Política Nacional de Resíduos Sólidos (PNRS, Brazil's National Solid Waste Policy), sets the order of priority: no generation, reduction, reuse, recycling, treatment and, last, environmentally sound final disposal.

In practice, a return you prevent is worth more than a return you recycle.

That leads to two decisions. First, attack the cause of returns with accurate descriptions, size charts and real product photos. Second, decide category by category whether bringing an item back makes sense. Reselling a returned item beats shredding it, because it keeps the energy and material already built into it. For low-value items sold abroad, compare the cost and emissions of the return leg with options at destination, such as a refund without return or a donation through a local partner.

What does Brazilian law require from sellers and importers?

Article 33 of the PNRS requires manufacturers, importers, distributors and retailers of six product groups to run take-back systems that operate independently of public waste collection: pesticides and their packaging, cells and batteries, tyres, lubricating oils, certain lamps, and electrical and electronic products with their components.

The word that catches e-commerce businesses is "importers". If you sell headphones, chargers or batteries into Brazil, your Brazilian importer of record is part of the obligated chain, even though nothing was made locally. The same article allows regulations and sector agreements to extend take-back duties to plastic, metal and glass packaging.

To prove what was recovered, Decree No. 11,413/2023 created three voluntary certificates: the CCRLR (reverse logistics recycling credit certificate), the CERE (packaging structuring and recycling certificate) and the future-mass credit certificate.

What changed in 2026 for companies selling to Europe?

Three European rules take effect in 2026, the last one on 27 September, and they touch returns, packaging and marketing claims. They apply to operators in the EU market, so a Brazilian exporter feels them whether it sells direct to consumers or through an importer. The table sets them next to the Brazilian rules.

The fashion rule bites first. Under the ESPR, an "unsold product" includes an item returned within the withdrawal period, and "destruction" includes discarding it as waste. So the T-shirt back from Lisbon, if it belongs to a large company, has to go to resale, donation, repair or preparation for reuse, with exceptions such as damage that cannot be repaired at a sensible cost.

The same company must also disclose every year how many unsold products it discarded and why (art. 24). Micro and small companies are outside the ban, according to the text of Regulation (EU) 2024/1781 published on EUR-Lex and checked in September 2026.

On packaging, the PPWR has applied since 12 August 2026, but the targets that matter most for e-commerce start in 2030. Empty space is capped at 50%, and bubble wrap, shredded paper and polystyrene chips count as empty. For transport packaging, 40% will have to be reusable within a reuse system, with cardboard boxes excluded from that target (EUR-Lex, Regulation (EU) 2025/40, checked in September 2026).

Four years go by fast when you need to redesign a box, test it with customers and renegotiate with a supplier. Material options are compared in the guide to sustainable packaging in logistics.

How do you get returned products back into the loop?

It starts at the receiving dock. Before the first return arrives, decide where each product condition goes:

• Intact with tags: back into sellable stock on the same business day.
• Signs of use or opened packaging: outlet or sale as pre-owned.
• Repairable defect: fix and resell with your own warranty.
• Beyond repair: harvest spare parts, and send the rest to recycling with a certificate of destination.

Returnable packaging works in repeated flows between fixed points. Between your factory and a distributor that orders every month, a foldable plastic crate can make trip after trip. In one-off sales to consumers in another country, the crate rarely comes back.

Buy-back and recycling programmes need easy returns. In the DHL eCommerce 2026 E-Commerce Trends Report, 58% of online shoppers said they would join a retailer's recycling or buy-back programme if returns were free and easy. The survey covered 29,000 consumers in 29 countries between December 2025 and February 2026.

Brazilian sellers with regular overseas sales gain from consolidating returns. Instead of each customer shipping a parcel back to Brazil, collect the returns at a partner address in the destination country and bring back one batch: fewer legs, lower emissions per item and one shipment to document.

Goods exported from Brazil that come back follow their own customs rules, explained in the guide to e-commerce logistics in Brazil.

Which indicators prove the environmental gain?

Six numbers support a report you can defend. Track them by quarter and by product category:

• Reuse rate: items resold, repaired or donated divided by items returned.
• Documented destination: weight backed by an invoice, certificate or destination report divided by total returned weight.
• Emissions per return, in kg of CO2e per unit, taken from your carrier's report.
• Cost per returned unit against the value recovered on resale.
• Trips per returnable package, where you use them.
• Your top three return reasons, because that is where prevention lives.

A worked example: if 1,000 items came back in the quarter and 640 were resold or repaired, your reuse rate is 64%. The other 36% is your work plan for next quarter.

Where does lower-emission transport fit in?

The freight on a return counts toward the company's indirect emissions, Scope 3 in the GHG Protocol. To cut that figure without changing the route, DHL Express offers GoGreen Plus in Brazil, which reduces air transport emissions through the purchase of sustainable aviation fuel (SAF) on a book-and-claim basis.

According to the DHL Express Service and Rate Guide 2026 for Brazil, SAF can reduce lifecycle emissions by up to 80% compared with conventional jet fuel, and the process is audited every year by SGS. The company's 2030 targets include 30% SAF blending across all air transport and 66% of last-mile vehicles electrified, on the way to net-zero emissions in 2050.

Service details and other lower-impact practices are in the guide to sustainable shipping with DHL.

How do you communicate sustainability without greenwashing?

With a number, a method and a period, never with an adjective. From 27 September 2026, Directive (EU) 2024/825 bans, in sales to European consumers, generic environmental claims such as "eco-friendly" or "green" without recognised performance. It also bans saying a product is carbon neutral on the basis of offsetting. Source: EUR-Lex and European Commission, checked in September 2026.

Shoppers hold brands to account as well. In the same DHL eCommerce report, 35% of shoppers said they had abandoned an online purchase because the store lacked sustainability credentials. A credential is something you can prove: "64% of this quarter's returns went back on sale" persuades more than any badge your marketing team designs.

If your team wants to cut emissions beyond returns, the guide on how companies reduce their carbon footprint shows where to start.
