Everything you need to know about compostable PPE, biodigesters, and sustainable healthcare solutions.
01
Compostable PPE
Frequently asked questions about compostable personal protective equipment
All our compostable PPE products are certified to EN13432, the European standard for industrial compostability. This means they will break down within 90 days in industrial composting conditions, leaving no harmful residues. Some products also carry AS4736 (Australian) and OK Compost Industrial certifications.
In industrial composting conditions (55-60°C with proper moisture and oxygen), our compostable PPE breaks down within 90 days. When processed through a biodigester, this can be as fast as 24 hours. In home composting conditions, breakdown may take longer as temperatures are typically lower.
Yes. Our compostable aprons meet the same fluid barrier standards as traditional plastic aprons. The materials are fully waterproof and provide identical protection against splashes and contamination. The only difference is what happens after disposal.
Contaminated PPE can be processed through high-temperature biodigestion (70°C+), which kills pathogens. For industrial composting collection, check with your waste provider about their policies on contaminated materials. Always follow your facility's infection control guidelines.

Biodigesters
Common questions about on-site biodigestion systems
Biodigester pricing varies based on capacity and features. The Harp CX series starts from approximately €15,000 for smaller units. Most healthcare facilities see ROI within 2-3 years through reduced waste disposal costs. Contact us for a detailed quote based on your waste volumes.
Biodigesters require minimal maintenance—typically monthly checks of filters and quarterly deep cleans. HaPPE Earth provides full maintenance packages including remote monitoring, preventive maintenance visits, and 24/7 support for any issues.
No. The Harp biodigester is a fully enclosed system operating at high temperatures (70°C+). This eliminates odours during processing. The output fertiliser is also odour-free, unlike traditional composting methods.
The Harp CX2 processes up to 2,000 litres (approximately 315 lbs/145kg) of organic waste per week. Larger models are available for facilities with higher volumes. We'll assess your waste streams to recommend the right capacity.

Ordering & Delivery
Questions about purchasing, delivery, and returns
For B2B products (aprons, hairnets), minimum orders are typically 500-1,000 units depending on the product. For consumer shoe covers, there's no minimum—you can order single packs of 100 online. Bulk discounts apply for larger orders.
Standard delivery within Ireland is 2-3 business days. Express next-day delivery is available for orders placed before 2pm. B2B orders for larger quantities may require 5-7 days lead time. Biodigester installation is scheduled based on site readiness.
Unopened products can be returned within 30 days for a full refund. Due to hygiene requirements, we cannot accept returns of opened PPE packaging. If you receive damaged or incorrect items, contact us immediately and we'll arrange a replacement.
Yes! Shoe cover bulk pricing: 5+ packs (10% off), 10+ packs (20% off), 25+ packs (30% off). For B2B products, we offer customised pricing based on annual volumes. Contact our sales team for a quote.

Sustainability & Certifications
Questions about environmental impact and certifications
EN13432 is the European standard for packaging recoverable through composting and biodegradation. Products certified to EN13432 must: break down within 12 weeks, disintegrate within 90 days, leave no toxic residues, and not negatively impact compost quality. It's the gold standard for compostability.
Compostable PPE typically has a 60-70% lower carbon footprint than plastic equivalents. The plant-based materials absorb CO2 during growth, and manufacturing processes are less energy-intensive. When combined with biodigestion (carbon-negative), the overall impact is dramatically lower.
Switching from plastic to compostable PPE is directly reportable under ESRS-E5 (Resource use and circular economy) for CSRD compliance. We provide documentation including volumes, certifications, and carbon calculations to support your sustainability reporting.
Yes. All HaPPE Earth PPE products are manufactured in Ireland using imported plant-based raw materials. This ensures quality control, reduces transport emissions, and supports local employment. Biodigesters are also manufactured in Ireland by our partner Harp Renewables.
