Phoenix™ LBC-199 is the compact LBC Facility (Automatic) configuration of the Phoenix™ Composting Toilet—designed for eco-residential, eco-commercial, and council projects pursuing Living Building Challenge goals. Where plant space is tight but uptime and hygiene can’t be compromised, LBC-199 delivers proven Phoenix™ biology and odour control in a low-height footprint that fits tight plant rooms and low sub-floors. The package emphasises materials transparency and on-site waste treatment strategies aligned with LBC’s Materials and Water Petals.
Capacity
Residential rating: 2 persons continuous use (assume ~6 uses/person/day).
Vistor Rating: day-visitor daily average (28/person/day). Short surges are typically tolerated at ~30% above day-visitor daily average.
Public/day-visitor or light household use: final single-use/day-visitor guidance set by WCTNZ® to suit each site (hourly peaks, climate, venting).
Peaks: short surges (events/holiday periods) are typically manageable when designed and serviced to plan.
Scaling strategy: deploy multiple LBC-199 units or combine with larger models for distributed stalls; plan clear service access for mixing and annual removal.
Features
Odourless operation: continuous 12 V ventilation maintains negative pressure through the chute and vent stack—fresh interiors even during peaks.
Automatic package: spray/recirculation system with robust controls; service-friendly access doors with vandal-resistant hardware.
Mixing system: heavy stainless rake/tine geometry built for public-duty reliability.
Built to last: cross-linked polyethylene chamber with stainless fasteners stands up to seasonal extremes.
Flexible interfaces: waterless dry via Ø310 mm vertical chute, or micro-flush / vacuum-flush where offsets or same-floor runs are required.
Serviceable design: annual compost removal via the lower access door; straightforward checks for fan, vent, drains, and spray system.
Low energy demand: ~5 W continuous—simple to run from solar/battery systems.
Bathroom Fixture options
- Waterless dry toilet via 12" (~310 mm) vertical chute for the simplest, lowest-maintenance install. (ZERO DISCHARGE SYSTEM)
- Micro-flush (≈0.5 L) or vacuum-flush options where architectural layouts need offsets or same-floor runs.
LBC Alignment & Documentation
Materials transparency / Red List screening support: WCTNZ® supplies an ingredient & component pack (cut-sheets, BOM detail and SDS where available) to support LBC Red List screening and Declare-style reviews by project teams.
On-site water strategy compatibility: supports on-site treatment approaches valued in the Water Petal (subject to local approvals). WCTNZ® provides commissioning/O&M templates to align with consent and asset-management expectations.
Early-phase coordination: we can align with LBC workflows so materials vetting and water strategy decisions are made early.
Note: Phoenix™ is not represented here as a pre-certified LBC product; compliance depends on project-specific selections and full documentation.
Applications
Eco-residential and eco-commercial projects adopting water-frugal and on-site treatment strategies.
Council-led pilots and demonstration sites seeking low-odour, low-power sanitation aligned with LBC Petal goals.
Small public nodes (trailheads, pocket parks, lookouts, satellite pods) that need compact equipment with formal materials/water documentation.
