Bioethanol production turns your waste into an advantage

Waste and residues have transformed from useless leftovers into usable raw-material that may actually turn into an advantage for your business – be it fuel for your transportation fleet, electricity, profitable business or a company principle that is important for your customers.

Traditionally, waste management is seen as costly and time-consuming necessity and inconvenient task that disturbs business activities.

What if it could be turned into money-saving benefits or even profitable and responsible business?

We offer efficient and traceable alternatives for waste

Our processes from waste to ethanol are designed to be fluent and efficient for companies who supply the feedstock or produce the bio-ethanol. In practice, this means for example that there is no need to remove packaging from the off-spec products.

Employees are reported to have increased motivation when there is a hygienic and smart recycling solution available, and the requirements and licensing of waste treatment becomes easier for the company. This lowers the cost of handling waste and makes it faster.

Waste management is also risk management

Today waste disposal is looked after more carefully to ensure that the waste is taken care of in the proper way and to prevent misuses of waste. Companies are looking for sustainable and efficient alternatives that are reliable and in line with their values.

We have developed our process from the beginning to the end thinking of the most convenient and secure solutions that make the most out of waste. Whether it’s off-spec bakery products, out-of-date bread from retailing or organic municipal waste there is an efficient way to transform and refine these into usable, high-demand products that are traceable through to the end product, be it the primary product of bioethanol or side products such as fodder and biogas.

In this way, suppliers of raw-material can be sure of how and where their waste and off specs are used, providing a secure disposal solution. Moreover, detailed reports of how the waste has been used are provided to companies to ensure secured usage and traceability. We have hands-on knowledge of the risk management issues as we run our own bioethanol production in Finland.

Closed Loop – your own waste to fuel

When waste is fully reused, processed or refined into new products, it creates a loop. St1 Biofuels have developed a closed-loop model, which means that a company may refine its own biodegradable waste into bioethanol. Etanolix® plants produce sustainable bioethanol that can be used by the company's own transportation fleet and supplied to consumers as different branded blending mixtures through fuel stations.

Feedstock is consisting of

  • Bakery waste and process residues, e.g. dough
  • Retail food waste, such as surplus bread and sorted biowaste
  • Brewery waste and residues, such as surplus yeast and process residues from beverage production
  • Waste and process residues from confectionery production
  • Waste and process residues from potato-based products
  • Other waste and process residues that are rich in starch and sugar

  • Bioethanol production in logistics hubs

    Suitable feedstock for bioethanol production is generated every day in the food retail sector. When integrated with a centralized logistics hub, bioethanol production brings efficiency and sustainability to both waste management and logistics. Logistical arrangements have a key role in the planning of a bioethanol plant and an effect on the overall profits, costs and the sustainability.

    Biodegradable waste products, such as surplus bread and other out-of-date food, are processed in a cost-efficient and risk-free way by taking it back to the hub, from which the waste is easy to collect or transport to ethanol plant and turn into bioethanol.

    Waste management is hygienic and easy as packaged products are also allowed in the process. Additional feedstock can be collected from bakeries nearby. St1 Biofuels have vast experience of various waste collection models.

  • Utilizing waste and residues to the last bit

    Production of food products always generates some amount of waste. Bioethanol production turns these remaining resources into sustainable and valuable fuel – bioethanol. Out-of-date products, faulty batches and residues can be used as feedstock in Etanolix® plants.

    Etanolix® technology is also the only solution capable of handling heterogeneous feedstock. The most suitable feedstock is rich in starch and sugar. Packaged and unpackaged products are both suitable for the process, which produces either animal feed or combined heat and power and soil conditioner as side products.

    Funneling waste to one single use, bioethanol production, makes waste management risk free and easy to trace.

  • A winner for environmental corporate governance

    An Etanolix® plant is designed to minimize the environmental impact in every phase of the process.

    The actual plant is nearly odor-free and it has a small ecological footprint. The process is designed to be clean and rather odorless, which is convenient for everyone involved in the process.

    Ethanol produced in an Etanolix® plant is almost carbon-neutral; this is due to utilizing renewable energy in heat and power generation.

  • High quality fodder for animals

    Waste-based bioethanol production produces animal feed as a side product due to the similarities in feedstock.

    The Etanolix® process converts packaged and unpackaged fermentable biowaste into valuable bioethanol. The side product, liquid animal feed, is high in protein and suitable for pig nutrition. The high quality of the fodder is ensured through rigorous control system, approved by authorities.

    The process meets the criteria set for animal feed production as the process is done in hygienic way in high temperatures, where no animal products are allowed in feedstock. We deliver 3-4 truckloads of fodder every day and follow the process constantly.

  • Traceability – Learn and report how your waste is reused

    In waste management, it is important to know how waste is actually used. Therefore, our solutions include highly automated reporting and analysis systems that allow the customer and other stakeholders to follow exactly how their waste has been transformed and what the outcomes are.

    A detailed report is given on amounts, qualities, compositions as well as productivity from feedstock till outcomes and deliveries.

    Comprehensive reporting and analysis is something companies can report and educate their stakeholders and interested parties about.
