Hollow Blocks in Tanzania : A Study Regarding the Domestic Market for Sustainable Concrete Block Innovations

Sammanfattning: Abstract   Purpose: The purpose of the study is to identify why the Tanzanian market for cement blocks have not adapted hollow blocks instead of solid ditto and, if possible, present recommendations for market activities.   Design/methodology/approach: Implemented by action research methodology, this minor field study financed by Swedish International Development Cooperation Agency targets issues regarding the relatively poor housing standard in Tanzania through a business development perspective. Furthermore, the study covers what obstacles for new, more sustainable and price-efficient products are to identify in the Tanzanian market.   Findings: An implementation of hollow blocks in the concrete block market surrounding Dar es Salaam would be beneficial from several aspects (e.g. economical, environmental, societal), but there are also factors that hinder such an implementation. The market’s consumers tend to not get the information about new techniques and innovations; hence to this lack of knowledge and awareness of alternatives, they stick to more traditional ways that they know more of. The consumers that do know of the new materials often disbeliefs the producers’ ability to make the quantity or quality demanded. Unawareness and distrust results in that few ask for new alternatives. The producers who put their main focus on supplying what the customers specifically asks for will therefore not start to produce the new alternatives, in this case hollow blocks. Thus, new innovations and the knowledge of the production of it do not spread easily. To implement new innovations some actor(s) to bare the risk is needed - pioneers that either commence producing the material themselves or, at least, encourage/provide incitements for producers and consumers to gain knowledge of them. The ones who have the possibility to carry risks in the concrete market surrounding Dar es Salaam are the large cement producers and the governmental institutions. They are also stakeholders who will benefit the most from taking the pioneer approach.   Originality/value: The study offers insights into the Tanzanian market for cement blocks for building construction by focusing on adaption of a block innovation that can reduce the Co2 emissions due to less raw material use per block.   Keywords: Sustainable Business Development, Innovation, Housing standard, Tanzania.   Type of study: Bachelor Thesis in Enterprising and Business Development, Linnaeus University, Sweden.
