Recycled Plastic and Aluminum Composite Toilets for Sustainable Waste Management in High-Altitude Environments

Project in-detail

Utilizing recycled plastic and aluminum composite materials, the facility integrates a composting toilet system designed specifically for high-altitude waste management, addressing sanitation needs while reducing environmental impact.
5 key facts about this project
01
Utilizes recycled plastic and aluminum composite materials specifically adapted for high-altitude conditions.
02
Incorporates a urine-diverting composting toilet system to manage waste efficiently without water.
03
Modular design allows for easy relocation and expansion based on seasonal visitor flow.
04
Educational diagrams promote user engagement and proper waste disposal practices.
05
Integrates local materials like bamboo for fixtures, maintaining a natural aesthetic while promoting sustainability.

The project titled "Encased" proposes an innovative solution for waste management at Everest Base Camp. As an architectural response to the increasing number of visitors in this environmentally sensitive area, it serves as a self-sufficient composting toilet facility. The facility is designed specifically to manage human waste effectively while minimizing its ecological footprint, positioning itself as a functional and sustainable architectural intervention in a remote and challenging environment.

Unique Design Approaches

Central to the project is its composting toilet system, which differentiates it from conventional restroom facilities. This system manages waste without relying on water, thereby addressing the scarcity of water resources in high-altitude locations. The architecture facilitates a urine-diverting dry toilet, which allows for efficient separation of liquid and solid waste to enhance composting processes, reducing environmental pollution and the risk of disease transmission.

The outer shell of the structure incorporates recycled plastic and aluminum composite panels, which contribute to its lightweight nature while providing substantial durability against the extreme weather conditions prevalent in the Himalayas. The design emphasizes modular adaptability, enabling the facility to be relocated or expanded as required. This flexibility is vital in response to fluctuating visitor numbers and seasonal climatic variations.

Functional and Aesthetic Considerations

The architectural design of "Encased" integrates functional requirements with aesthetic considerations to blend seamlessly into the surrounding landscape. The use of local materials, such as responsibly sourced wood or bamboo for interior fixtures, helps maintain a natural aesthetic and aligns with principles of sustainability. The facility is not only a restroom but also includes designated areas for waste segregation, reinforcing the importance of recycling and waste reduction among visitors.

Furthermore, the project features visual guides and instructional diagrams that clarify the operational aspects of the composting system. This educational side aims to inform users about proper waste disposal practices, fostering a culture of ecological stewardship among visitors.

Through its unique design features, "Encased" presents an architectural solution that effectively addresses sanitation needs while considering environmental integrity. This project stands as a model for future developments in sensitive ecological zones, providing practical insights into sustainable architecture.

MICROHOME 10: Celebrating Small-Scale Living with €100,000 Prize Fund and Kingspan’s Innovation

`
Competition organisers

The MICROHOME 10 competition invites participants to submit visionary designs for off-grid, modular microhomes that push the limits of sustainable, small-scale living. Organised by Buildner in partnership with Kingspan and Hapi Homes, this tenth edition sets the challenge of designing a dwelling for two people within a maximum floor area of 25 m², encouraging bold solutions adaptable to any urban or rural location. The competition continues Buildner’s mission to foster innovative approaches to compact, energy-efficient housing that can address pressing global challenges.

This year’s edition offers a generous total prize fund of €100,000, including the Kingspan Award for designs that integrate high-performance Kingspan products and the Hapi Homes Award for a project selected for real-world construction. In addition to cash prizes, the winners gain international exposure through Buildner’s media partnerships, publications, and a dedicated MICROHOME magazine, further amplifying their ideas to the wider architectural community.

Key dates for MICROHOME 10 include the closing date for registration on 25 September 2025, the submission deadline on 29 October 2025 (11:59 p.m. London time), and the announcement of winners on 9 December 2025. These milestones ensure participants have clear timelines to develop and present their concepts, with early registration discounts available to support students and emerging designers worldwide.
