A way to deal with about 500 tons of sulfur dioxide emitted each year

Our company generates about 500 tons of SO2 per year, and the SO2 concentration in the gas can be adjusted as needed, ranging from 5% to 50%. But there is no simple way to handle it now. I don’t know what method would require the least investment, be the simplest in terms of technology, and result in products or waste that are easy to handle. It seems that this amount is neither too high nor too low; calcium hydroxide is used for absorption, and it appears that a considerable amount is consumed – around 1,000 tons per year. The gypsum produced isn’t removed either ； If it’s to produce sulfuric acid, it doesn’t seem very interesting. I don’t know which method is the most suitable.
