Complex organic molecules are found everywhere in the interstellar medium, especially in the warm and dense gas close to forming stars, from which planets eventually emerge. Understanding the origin of these molecules and their chemistry is important to determine the complexity of chemistry that can develop, and its potential implications to life in the universe. These molecules can also be used as tools to understand the mechanisms central to the formation of stars. ALMA has revolutionised the observation of these molecules, providing the tools to perform unbiased surveys of the molecular content on solar system scales. One such survey, the Protostellar Interferometric Line Survey (PILS), uses ALMA data to take a census of the chemistry in the solar-type protostellar binary IRAS 16293-2422, detecting over 10,000 lines at an unprecedented spectral and spatial resolution. This talk will explore the key results from this survey, and on-going projects which are expanding our understanding of physical structure and evolution of star-forming regions, building up a picture of the chemical variability of star-forming regions in a statistical meaningful way.
