L'intention comportementale dans les pratiques ménagères : faire soi-même son produit ménager pour moins polluer

Partly due to everyday products discharge, the presence of micropollutants in the sewage system highly concerns the public authorities and water stakeholders. Our study is focused on the measurement of the intention to substitute usual household products by a “homemade” product more eco-friendly. 304 questionnaires were completed by the inhabitants of the Strasbourg Eurometropole and were analyzed by using the theory of planned behavior (TPB). The results show that TPB explains 35 % of intention to use the “homemade” product. It seems that the respondents have a positive attitude toward this “homemade” product. It also appears that there is a strong capacity constraint of this product in terms of disinfection although this parameter is essential when choosing a household product.
