Embrace a Greener Lifestyle
Every Owlpack product has been tested by an independent third party — not self-assessed. BPI and ASTM D6400 confirm the Yucksacks bags break down in industrial composting without leaving toxic residue. TÜV Austria confirms they meet home composting standards too. GRS traces the recycled content in our mailers through the full supply chain. ETL and RoHS cover electrical safety and hazardous substance limits on every lamp.
These aren't signals of intent. They're test results.
BPI Certified
BPI is North America's leading third-party certifier for compostable products. To earn it, Yucksacks were independently tested against ASTM D6400—verifying they break down in industrial composting facilities within 90–180 days without leaving toxic residue or heavy metals behind.
If your city collects compostable waste, Yucksacks belong in that bin.
ASTM D6400
ASTM D6400 is the standard behind the BPI mark—the actual science that compostability claims are measured against. It runs four tests: elemental composition, biodegradation rate, phytotoxicity (whether the resulting compost inhibits plant growth), and particle filtration. A product must pass all four within 90–180 days to qualify.
This is why "compostable" on a Yucksacks bag means something a self-declared "biodegradable" label does not. ASTM D6400 doesn't take the manufacturer's word for it.
TÜV Austria
Industrial composting runs hot—typically above 55°C—which is what makes it fast and reliable. Your backyard pile doesn't. TÜV Austria's OK Compost Home certification verifies that Yucksacks break down under those cooler, slower, less controlled conditions, too.
Most compostable bags are certified for industrial facilities only. Yucksacks work in both. If you compost at home, you don't need to check whether your city program accepts them—they're already covered.
GRS – Global Recycled Standard
GRS certification means the recycled content in Owlpack's mailers and Si Balcón lamps has been traced through every stage of the supply chain—from the source material through processing and manufacturing to the finished product. That chain of custody is audited by a third party, not self-reported.
It also sets social and environmental requirements at each production stage, covering things like wastewater treatment, chemical use, and worker conditions—not just whether the material was technically recycled.
"Made with recycled content" without GRS is a manufacturer's claim. With it, someone independent has checked the receipts.
Recycled Claim Standard
RCS verifies that the Owlpack × Si Balcón lamps contain a declared percentage of recycled content—traced and audited through the supply chain, not self-reported. Unlike GRS, which covers the full production process, RCS focuses specifically on recycled content claims, making it the right standard for products where recycled material is one verified input among others.
Forest Stewardship Council
FSC certification covers the paper and fiber in Owlpack's product packaging — the boxes your lamps and bags arrive in. It means those materials were sourced from forests independently audited for biodiversity protection, sustainable harvest rates, and fair labor practices. No virgin fiber from unmanaged sources.
The product is considered. So is the box it comes in.
ETL Certified
ETL listing means our lamps were tested by Intertek—an independent, accredited lab—against the same North American electrical safety standards required for all residential lighting. That covers wiring construction, insulation integrity, heat tolerance, and safe behavior under both normal use and fault conditions.
ETL and UL are equivalent standards administered by different accredited bodies. Either mark means the same thing: an independent lab signed off, not the manufacturer.
RoHS Compliant
RoHS limits the use of six harmful substances in electronic products: lead, mercury, cadmium, hexavalent chromium, and polybrominated biphenyl. All Owlpack lamps are manufactured without any of the above permitted threshold levels.
The issue matters twice—once when you use the lamp and once when you eventually dispose of it. These are the substances that make electronics genuinely hazardous at the end of life, contaminating soil and groundwater when they reach landfills. RoHS compliance means that these substances are not present in the lamp to begin with.
