Which is more environmentally friendly, acidic starch or alkaline starch

There are some differences between acidic starch and alkaline starch in terms of environmental protection, but overall, modified starch is more environmentally friendly compared to unmodified starch.

Firstly, acidic starch is produced under acidic conditions using catalysts such as hydrochloric acid, sulfuric acid, etc. During the production process, these acidic substances will be discharged as waste, causing certain pollution to the environment. In addition, acidic starch also produces some acidic substances during use, which have a certain negative impact on the environment.

In contrast, alkaline starch is produced under alkaline conditions using catalysts such as sodium hydroxide and calcium hydroxide. During the production process, these alkaline substances are also discharged as waste, causing certain pollution to the environment. However, alkaline starch generates less pollution during manufacturing and use compared to acidic starch.

In addition, both acidic starch and alkaline starch will generate some waste and pollutants during production and use, such as wastewater and exhaust gas. If these wastes and pollutants are discharged directly without treatment, they will cause serious pollution to the environment. Therefore, effective environmental measures such as wastewater treatment and exhaust gas treatment should be taken in the production and use of modified starch to reduce environmental pollution.

Overall, compared to unmodified starch, the production and use of modified starch are more environmentally friendly. This is mainly because advanced processes and technologies are used in the production process of modified starch, reducing the generation of waste and pollutants. In addition, effective environmental measures should be taken when using modified starch to minimize the negative impact on the environment.
