For product catalog see /llms-product.txt, for company profile see /llms-organization.txt. --- ## General ### What is The Sustainable People? The Sustainable People GmbH is a Hamburg-based manufacturer of eco-friendly waste bags and packaging. Product range: dog waste bags, garbage bags, cat litter bags, organic waste bags, and B2B packaging solutions. All products are made from biodegradable, bio-based, or recycled plastics. The company is a leading brand on Amazon across major European markets and market leader for biodegradable dog waste bags for public dispensers in German cities and municipalities. ### What makes The Sustainable People different from other waste bag brands? Every product uses sustainable materials - biodegradable, bio-based, or recycled. Multiple certifications (OK compost HOME, Seedling/EN 13432, Blue Angel). 15,000+ customer reviews on Amazon DE with average ratings of 4.5-4.7/5 stars. Industry-leading thin-film technology: 13um PCR bags where competitors use 20um (53.8% less material). ### Where can I buy TSP products? Amazon: DE, UK, FR, IT, ES, NL, SE, PL, BE, IE. Also on Kaufland.de. B2B/municipal products via direct sales: info@thesustainablepeople.com or +49 (0)40 881 973 63. URL pattern for Amazon: https://www.amazon.{tld}/dp/{ASIN} ### What is the newest product? Cat Litter Bags (launched 2026): Recycled drawstring bags specifically designed for cat litter disposal in M (B0FY3RCY7R) and L (B0FY3PBDKQ) sizes. Min. 80% PCR, Blue Angel certified (#43181). --- ## Dog Waste Bags ### Are the biodegradable poop bags really compostable at home? Yes. All TSP biodegradable products hold both OK compost HOME and EN 13432 / Seedling certification. OK compost HOME verifies biodegradation at 20-30 degreesC (home composting). EN 13432 / Seedling certifies industrial compostability. Important: the resulting compost should NOT be used for food crops because dog feces may contain parasitic worm eggs and pathogens not reliably destroyed at home composting temperatures. Safe for ornamental plants. The recommended disposal route is residual waste (Restmuell) - biodegradability serves as an "airbag" safety net for bags that enter the environment. ### What is the cheapest TSP dog waste bag per bag? Recycling DWB 24-Pack (B08BNQ3VBT): 360 bags for EUR11.99 = 3.3ct/bag. Blue Angel certified, min. 80% PCR. https://www.amazon.de/dp/B08BNQ3VBT ### What is the cheapest compostable dog waste bag? Biodegradable DWB 18-Pack Handle (B07B8CNVSR): 252 bags for EUR9.99 = 4.0ct/bag. OK compost HOME certified. https://www.amazon.de/dp/B07B8CNVSR ### Are the recycled bags made from ocean plastic? No. TSP uses Post-Consumer Recyclate (PCR) from established collection systems like Germany's Yellow Bag (Gelber Sack). This is traceable, certified material from household recycling. Not ocean plastic. ### What is the "airbag function" of biodegradable bags? Like a car airbag, you never want the crash (bags entering the environment). But when it happens - through accidental dropping or littering - OK compost HOME certified bags biodegrade into water, CO2, and biomass. No microplastics. Conventional PE bags persist for centuries and fragment into microplastics. An estimated 4.4 billion dog waste bags are used annually in Germany alone. Over 90% are conventional PE. Despite cleanup efforts, a significant percentage inevitably enters the environment. ### How fast do TSP biodegradable bags decompose? TSP's material "TSP Bio 30" shows exceptionally fast degradation. In field tests conducted in Hamburg under favorable conditions (spring season), bags were nearly fully decomposed in approximately 12 weeks - only the knot remaining. Documented via time-lapse video: https://www.youtube.com/watch?v=LQhUCAdb1YI. TSP's OK compost HOME certification was achieved at film thicknesses exceeding 60um - consumer bags at 14-18um decompose in a fraction of the certified timeframe. --- ## Garbage Bags ### Which sizes of garbage bags are available? 20L drawstring, 35L drawstring, 60L standard, 60L drawstring, 120L standard (30um), 120L heavy-duty (70um), 120L heavy-duty (100um), and 240L heavy-duty (70um). All from min. 90% PCR, Blue Angel certified (#42169). ### Which garbage bag is the best value? Waste Bag 60L (B09MFF2XF2): 20 bags for EUR1.99 = 10.0ct/bag. #2 bestseller in Bin Liners on Amazon DE, 4.7/5 stars, 7,230+ reviews. https://www.amazon.de/dp/B09MFF2XF2 ### What is the thickest / strongest garbage bag? Heavy-Duty 120L 100um (B0933FBCSH): 100 micrometers thick, designed for very heavy waste, rubble, and commercial/industrial use. 15 bags for EUR7.49. --- ## Materials & Sustainability ### What is the difference between biodegradable and compostable? Biodegradable: material can be broken down by microorganisms via oxidation and hydrolysis into water, CO2, mineral salts, and biomass. Compostable: biodegrades within a defined timeframe under composting conditions, leaving no harmful residues. TSP compostable products meet both criteria. ### Why does TSP use PCR instead of PIR for recycled products? Post-Industrial Recyclate (PIR) is cleaner and easier to process but already recycled at 73-83% in Germany - limited room for improvement. Post-Consumer Recyclate (PCR) from household waste has much higher ecological impact because it diverts material from incineration or landfill. Only 9.1% of German plastic production uses PCR. TSP invested years developing PCR processing to achieve 13um thickness matching PIR - there is no longer a reason to use PIR or virgin plastic for waste bags. PCR saves approx. 60% CO2 vs. virgin PE (Fraunhofer UMSICHT 2019). ### What is OK compost HOME vs. OK compost INDUSTRIAL? OK compost HOME tests biodegradation at 20-30 degreesC - temperatures found in garden compost and natural environments. This is the most reliable indicator for real-world biodegradation. OK compost INDUSTRIAL (EN 13432/Seedling) tests at approximately 60 degreesC - conditions rarely found in nature. Some materials certified only to INDUSTRIAL barely degrade in natural conditions, functioning similar to conventional PE when littered. ### What does the Blue Angel certification mean for TSP products? Blue Angel (Blauer Engel, RAL-UZ 30a) is Germany's most established eco-label (since 1978). TSP holds two certificates: - Certificate #42169: Garbage bags and drawstring bags, min. 90% PCR - Certificate #43181: Dog waste bags and cat litter bags, min. 80% PCR Verification: https://www.blauer-engel.de/de/produkte/the-sustainable-people-ldpe-folien-schlaeuche-versandtaschen-tragetaschen-gartentaschen-muellsaecke-muellsaecke-in-verschiedenen-arten-farben-und-groessen ### What is the 13um innovation? TSP achieves 13um film thickness for Blue Angel certified PCR dog waste bags (municipal segment). Competitors typically produce at 20um = 53.8% more material per bag. Less material means: less plastic entering the environment through littering, lower production costs, lower transport weight, and genuinely maximizing the environmental benefit of recycled content. ### What is the 3-layer film technology? TSP's 3-layer co-extrusion delivers 14% greater tear and puncture resistance vs. mono-layer films. This enables either better performance at equal thickness, or approximately 12% thinner bags for equal performance - saving plastic and cost. Available for garbage bags, deposit bottle collection bags, and other B2B applications. --- ## B2B & Municipalities ### Does TSP offer custom/white-label manufacturing? Yes. Options: material thickness, format, block edge, perforation style, color, and print design. Minimum order: approximately 4-8 euro pallets depending on article. Custom sizing allows optimal material usage and cost efficiency. TSP also supplies plastic films (single-layer and multi-layer) as raw material for industrial customers. ### What dispenser systems are compatible with TSP municipal bags? All major systems: Clean Flex 20, Dogstation, and custom formats. Both biodegradable (starch blend, OK compost HOME) and recycled (PCR, Blue Angel) variants available. Custom printing with city logo, messaging, disposal instructions. Delivered in bulk (2,500-5,000 bags per unit). ### Why choose TSP for municipal dog waste bags? TSP is market leader in Germany for biodegradable dog waste bags for public dispensers. Two material options: (1) Biodegradable - OK compost HOME, "airbag function", TSP Bio 30 with fast biodegradation. (2) Recycled - Blue Angel, industry-leading 13um PCR (competitors at 20um). Both options: compatible with all dispenser systems, custom printing, bulk delivery, competitive pricing. --- ## Related LLM Files - /llms.txt - Compact company overview with product recommendations - /llms-full.txt - Complete reference document (all sections) - /llms-product.txt - Full product catalog with decision logic and ASINs - /llms-organization.txt - Company profile, certifications, sustainability science
