What is the current and projected demand for sulfiding agents in the context of biofuel production?</span></h2><p style="text-align: justify;">We are still beginning the process, and the current demand for biofuel production is just several hundred tonnes per year. But if even half of the refineries switch to biofuel, they will need tens of thousands of tonnes of sulfiding agents.<span data-ccp-props="{"134233117":false,"134233118":false,"201341983":0,"335551550":0,"335551620":0,"335559738":0,"335559739":0,"335559740":259}"> </span></p><p style="text-align: justify;"> </p><h2 style="text-align: justify;"><span style="font-size: 12pt;">2. What challenges or limitations are faced in implementing green approaches for sulfur organics production, and how are they being addressed?</span></h2><p style="text-align: justify;"><span data-contrast="none">Unfortunately, the main source of sulfur is H2S from natural gas, and we can only do a little about this. However, the manufacturers invest a lot to reduce the pollution from production sights. They try to minimize the contact of sulfiding agents with the environment. Some end users switched to polysulfides which don't generate methane during decomposition and are easier to handle vs DMDS. </span><span data-ccp-props="{"134233117":false,"134233118":false,"201341983":0,"335551550":0,"335551620":0,"335559738":0,"335559739":0,"335559740":259}"> </span></p><p style="text-align: justify;"> </p><h2 style="text-align: justify;"><span style="font-size: 12pt;">3. How do stakeholders in the green fuel industry collaborate to ensure the responsible and sustainable utilization of sulfiding agents throughout the production and distribution processes?</span></h2><p style="text-align: justify;"><span data-contrast="none">The main way to increase efficiency is to provide maximum control of sulfiding agent injection. With equipment like H2S and H2 analyzers, we can reduce the quantity of sulfiding agents consumed by the refineries. The same is true for petrochemical plants; they need to have a well-designed dosage system to be sure they inject a proper quantity of sulfiding agent. Normally the manufacturers share those best practices with the end users.</span><span data-ccp-props="{"134233117":false,"134233118":false,"201341983":0,"335551550":0,"335551620":0,"335559738":0,"335559739":0,"335559740":259}"> </span></p><p style="text-align: justify;"> </p><h2 style="text-align: justify;"><span style="font-size: 12pt;">4.
