David Mullen (b. 1989, UK) is an artist who deals with the relevance of contemporary painting. A desire to reduce the waste created as a by-product of his paintings has recently led to a radical shift in his practice. His ambition is to create oil paintings that, if unsuccessful, could safely be put onto a compost heap rather than into landfill. The paintings must therefore be biodegradable and non-toxic. This has allowed him to cultivate his long-standing interest in colour and the materiality of paint, by forcing him to use natural earth pigments and organic pigments synthesised from plants, such as woad, weld and madder. The ultimate goal is to make paintings using pigments synthesised from plants grown in compost containing previous paintings.
