Macquarie Asset Management is reportedly pursuing a new takeover of Renewi Plc, a London-listed waste management company, after a previous offer was rejected last year. The asset manager is collaborating with advisers on the potential deal, which has led to Renewi's shares surging by up to 25%, marking their largest increase in 14 months. Despite this rise, the stock had fallen 13% this year, valuing the company at approximately £450 million ($569 million).
