Sample: 56 households
Evidence: Strong effect

Utilizing Bokashi fermentation for household food waste management in informal settlements can significantly divert waste from landfills and create valuable compost for local food production. This resource management research insight is drawn from a 2014 study published in SUNScholar (Stellenbosch University). Using Participatory action research (par) and transdisciplinary approach with 56 households, researchers explored how this design variable affects real-world outcomes. The key design takeaway: Incorporate biological waste processing methods, like Bokashi fermentation, into community-based design projects focused on resource recovery and urban food systems.

Bokashi Composting Reduces Landfill Waste by 6m³ and Supports Urban Agriculture

Utilizing Bokashi fermentation for household food waste management in informal settlements can significantly divert waste from landfills and create valuable compost for local food production.

SUNScholar (Stellenbosch University) · 2014

Key Findings

015851kg of food waste was collected, saving 6m³ of landfill space.
02Households generated between 5.2kg and 9.6kg of food waste per week.
03The processed waste showed potential for recycling, urban agriculture, and income generation.

Application

Design takeaway

Incorporate biological waste processing methods, like Bokashi fermentation, into community-based design projects focused on resource recovery and urban food systems.

How to apply

Implement community-led food waste collection and Bokashi treatment programs, followed by composting or Black Soldier Fly larvae cultivation for local use in urban gardens or sale.

Project actions

01Consider the specific waste streams and community needs when designing resource recovery systems.
02Explore partnerships with local authorities and community groups for implementation and support.

Method & Evidence

AimTo investigate the viability and impact of a Bokashi-based food waste management system within an informal settlement, assessing its potential for waste diversion and contribution to urban agriculture.

MethodParticipatory Action Research (PAR) and Transdisciplinary approach

ProcedureA pilot project involving 56 households collected food waste over five months. The waste was treated with Bokashi Effective Micro-organisms (Bokashi EM) and then either composted or used to feed Black Soldier Fly larvae. Laboratory analysis was conducted on the waste, compost, soils, and larvae residue to assess safety and sustainability.

Sample56 households

ContextInformal settlement (Enkanini, Stellenbosch, South Africa)

Variables

IVImplementation of Bokashi food waste management system

DVAmount of food waste diverted from landfill, quality of compost, potential for urban agriculture.

CVHousehold size, types of food waste generated, duration of the pilot project.

Strengths & Limitations

Strengths

+Practical, community-based approach.
+Integration of scientific analysis with social learning.

Limitations

The effectiveness of Bokashi might vary with different types of food waste or environmental conditions. The cost and accessibility of Bokashi EM for widespread adoption need consideration.

Reliability & validity

The study's reliability is supported by consistent data collection over five months and laboratory analysis. Validity is enhanced by the transdisciplinary approach and participatory methods, reflecting real-world conditions.

Think critically

To what extent can the success of this Bokashi-based system be replicated in different socio-economic and environmental contexts, and what adaptations would be necessary?

Design Principles

"Waste streams can be transformed into valuable resources through appropriate processing and integration into local systems."

This approach offers a practical solution for waste management challenges in densely populated areas, transforming a problematic waste stream into a resource. It empowers communities by providing opportunities for local food security and potential income generation through urban agriculture.

What This Means for Your Design

Using a special fermentation method called Bokashi for kitchen scraps in a South African informal settlement saved a lot of space in the landfill and could help grow food locally.

How to use in your project

1.Reference this study when exploring sustainable waste management solutions or community-based design projects.
2.Use the findings on waste diversion and resource creation to justify design choices.
