This research aims to provide a new product development model with an emphasis on environmental considerations and consumer participation. The model design was based on the grounded theory approach. The statistical population of this study includes all new product development experts in the food industry (including executives and academics) and thirteen experts selected by the snowball method. Results showed that the primary phenomenon involves activities and actions taken to develop a product based on environmental considerations and with the participation of consumers. The effective causes of new product development are divided into three categories: market, customer, and technical factors. The underlying conditions for product development are classified into two categories of infrastructure and capabilities. Also, penetrating interventionists were divided into three categories of cultural factors, risk management, and supportive factors. In addition, new product development includes three mechanisms: marketing, commercialization, and green design. The results of the product development model design emphasize on consequences of economic benefits and non-economic benefits.
