Up to 40% of the 340 workers at the sites are set to be made redundant, after LCC said it needed to make cuts to achieve an extra £223m of savings by 2020.
The recovery parks receive, store, treat and transport 240,000 tonnes of residual waste, 66,000 tonnes of organic waste and 78,000 tonnes of recyclate as part of a PFI contract between LCC and Blackpool Borough Council.
LCC will consider plans to close the composting treatment at the two plants and possibly other processing treatments depending on whether alternative disposal options are considered cheaper.
Food waste collections could also be axed if the £8.5m slash to its budget is approved.
County Councilor David Borrow, deputy leader of LCC, said these were outline proposals and that the Council is working with Global Renewables in order to consult with workers and trade unions.
