A new cleaner firelog has now been developed using waste fibre from the oil palm fruit bunches of South East Asia.
[citation needed] Unlike sawdust logs, these burn with zero sulfur emissions.
Other new types of firelogs include one made from waste wax-cardboard such as that used in the packing of perishable foods for shipment, which is used to create a compressed cardboard firelog, and another made from renewable Greek cotton plants, offering a high energy content.
These are made using plant or animal based renewable waxes such as palm oil.
Sulphur emissions are virtually eliminated with renewable firelogs as they do not contain paraffin waxes.
