Dominic and Cymene compare denialist and evangelical hate mail on this week’s podcast and then share a few reflections on Sunday’s trip to the top of Ok mountain. Then (16:53) we welcome the marvelous Amanda Boetzkes (https://amandaboetzkes.com) to the conversation so we can talk about her terrific new book, Plastic Capitalism (MIT Press, 2019). What is “waste art,” when did it take shape and with what motivations? We talk about how waste relates to energy and how “zero waste” sustainability discourse might paradoxically reinforce capitalist ideology and economy. We discuss how Bataille, Irigaray and Zizek inform an ethics of waste, the kinship of excess that exists between much art and waste itself, and the sado-masochism of plastic. From there we turn to the materialities, relationalities and temporalities that plastic creates, its refusal of degeneration and whether the looming shift from petroplastics to bioplastics makes any difference. We close on energy expenditure, the “carnal sun” and plastic as a condensed form of solarity.
