Cadbury processes cocoa beans from farms in Africa into chocolate at factories in the UK. The cocoa mass is sent to two factories, one to produce plain chocolate and the other to produce milk chocolate by adding milk and sugar. Additional ingredients like cocoa butter and flavorings are mixed in. Chocolate crumbs are pulverized and molded into bars. Cadbury uses market research and customer feedback to understand consumer needs and respond to criticism about issues like the fat content and potential health impacts of chocolate. The company focuses on business ethics like providing education, clean water, and fair working conditions for cocoa farmers.
