With coal-fired power as the core, the production of chlor-alkali products and PVC via the calcium carbide method is facing increasing pressure on profits; what are the alternatives?

PVC is produced using the calcium carbide method; due to rising raw material costs, the profit margin continues to shrink – how can this situation be overcome?
It seems there is no solution to this problem; the production process has already been finalized. As long as calcium carbide is used as the raw material, no matter how much efforts are made to reduce costs and improve efficiency, the results can only get as close as possible to the theoretical value.
A solution is now available: crude oil prices have risen, and the oil-based method is definitely no longer competitive with the calcium carbide method.
There’s a solution now – crude oil prices have risen.
Shift to producing high-value products in the chlor-alkali industry; in the long run, as long as advanced technology is available, such high-value products can generate profits. Moreover, smaller-scale operations allow for quicker adjustments, greater flexibility, and improved resilience to risks.
