The Kalund­borg Sym­bio­sis is a set of fac­to­ries and mu­nic­i­pal wa­ter treat­ment fa­cil­i­ties that re­cy­cle one an­other’s wa­ter, en­ergy, and waste. They also sell byprod­ucts such as fly ash, a coal-burn­ing residue, to other com­pa­nies. The sys­tem grew grad­u­ally through in­ter­com­pany agree­ments start­ing in the 1970s, when a lo­cal oil re­fin­ery started pip­ing ex­cess gas to a nearby fac­tory that man­u­fac­tured sheetrock. The re­cy­cling not only has en­vi­ron­men­tal ben­e­fits but also helps com­pa­nies lower costs. “If there wasn’t a good busi­ness case, we wouldn’t be do­ing it,” says Michael Hall­gren, se­nior vice pres­i­dent of mem­ber Novo Nordisk.
