Usina de Acucar Santa Terezinha Ltda is a Brazilian company that specializes in developing renewable energy projects in the biomass and waste sectors. The company is headquartered in the city of Santa Terezinha de Itaipu, in the state of Parana, Brazil. It was founded in 1947 and has since become a leading player in the Brazilian renewable energy market.

Usina de Acucar Santa Terezinha Ltda operates several sugar and ethanol mills in Brazil, which produce biofuels from sugarcane. The company has also invested heavily in renewable energy projects, particularly in the biomass and waste sectors. These projects aim to reduce greenhouse gas emissions, promote sustainable development, and contribute to the transition towards a low-carbon economy.

One of the main biomass projects developed by Usina de Acucar Santa Terezinha Ltda is the production of biomass pellets from sugarcane bagasse. Bagasse is a byproduct of the sugarcane milling process, and it is usually burned to generate steam and electricity for the mills. However, the company has developed a process to transform bagasse into pellets, which can be used as a renewable fuel for power generation and heating.

The biomass pellets produced by Usina de Acucar Santa Terezinha Ltda have a high calorific value and low ash content, which makes them an attractive alternative to fossil fuels. The company has already supplied biomass pellets to several customers in Brazil and abroad, including power plants, industrial boilers, and residential heating systems.

Another biomass project developed by Usina de Acucar Santa Terezinha Ltda is the production of biogas from sugarcane vinasse. Vinasse is a liquid byproduct of the ethanol production process, which is rich in organic matter and nutrients. The company has built a biogas plant that uses vinasse as feedstock to produce biogas, which is then used to generate electricity.

The biogas plant developed by Usina de Acucar Santa Terezinha Ltda has a capacity of 1 MW and can produce up to 7,000 MWh of electricity per year. The plant also produces organic fertilizer as a byproduct, which is used to improve soil fertility in the sugarcane fields. This project has not only reduced greenhouse gas emissions but also created new revenue streams for the company and contributed to the circular economy.

Usina de Acucar Santa Terezinha Ltda has also developed several waste-to-energy projects, which aim to reduce the amount of waste sent to landfills and generate renewable energy. One of these projects is the production of biogas from municipal solid waste (MSW). The company has built a biogas plant that uses MSW as feedstock to produce biogas, which is then used to generate electricity.

The biogas plant developed by Usina de Acucar Santa Terezinha Ltda has a capacity of 1.2 MW and can process up to 100 tons of MSW per day. The plant also produces organic fertilizer as a byproduct, which is used to improve soil fertility in the sugarcane fields. This project has not only reduced greenhouse gas emissions but also contributed to the reduction of waste and the promotion of sustainable development.

Another waste-to-energy project developed by Usina de Acucar Santa Terezinha Ltda is the production of biogas from pig manure. The company has partnered with local pig farmers to collect and process pig manure, which is rich in organic matter and nutrients. The biogas produced from pig manure is then used to generate electricity and heat.

The biogas plant developed by Usina de Acucar Santa Terezinha Ltda has a capacity of 0.5 MW and can process up to 10,000 cubic meters of pig manure per day. The plant also produces organic fertilizer as a byproduct, which is used to improve soil fertility in the sugarcane fields. This project has not only reduced greenhouse gas emissions but also created new revenue streams for the company and contributed to the circular economy.

Usina de Acucar Santa Terezinha Ltda is committed to promoting sustainable development and reducing greenhouse gas emissions through its renewable energy projects. The company has demonstrated that it is possible to transform waste into a valuable resource and generate renewable energy, while contributing to the circular economy and promoting sustainable development. With its innovative and sustainable approach, Usina de Acucar Santa Terezinha Ltda is a leading player in the Brazilian renewable energy market and a model for other companies to follow.
