Ethylene comes from oil or natural gas which is refined and 'cracked' by heating ethane, propane or butane or naptha from oil. For example the cracking process for methane may be represented as follows:

2CH4 C2H2 + 3H2

The by-products of these processes including hydrogen can be burned to provide energy on site and propylene is reclaimed as is valuable. These by-products are flammable but are not toxic nor cancer forming.
