In the production of bioethanol, bioethanol is often referred to as first, second or third generation - depending on which raw materials were used in the production. The first generation describes those biofuels that are made only from edible parts of plants. Because only a small part of the plant can be used, the result is that the land required for the cultivation of food and feed crops for biofuels is in competition with the cultivation of these for use as food. Because of this, the controversial tank-plate discussion arose over 10 years ago. This debate deals critically with the use of bioenergy within the ecological cycle system. In order to counteract the disadvantages of the first generation, global research is being carried out on the use of second and third generation raw materials. Above all, the goal is almost complete utilization of a plant.
For this reason, the second generation is primarily concerned with breaking down cellulose. Previously the lignocellulose-containing biomass contained in a food crop could not be broken down due to its chemical composition. The third generation cannot always be clearly distinguished from the second but is primarily concerned with a biomass from algae. In addition, it should be possible to use CO2 as a raw material in the future.
BrüggemannAlcohol applies this generation concept and seeks to obtain raw materials that do not compete with food production, such as those related to industrial waste products which would no longer be used anywhere else. By processing this waste, BrüggemannAlcohol supports the maintenance of the sustainable cycle concept.
Breweries are also a valuable source of raw alcohol for the Heilbronn alcohol manufacturer. In the production of non-alcoholic beer, the alcohol produced in the beer is removed after fermentation. What is considered a waste product that cannot be further processed by breweries, becomes an important raw material for BrüggemannAlcohol.
The sugar and starch industry has numerous side streams. These are by-products that arise during production and are already converted into ethanol today. This alcohol is refined to neutral alcohol in the Brüggemann factories.
Another example are re-distillates that BrüggemannAlcohol uses to make extracts. For phytopharmaceuticals, for example, medicinal plants are dissolved in alcohol. The alcohol used for the extraction is then distilled off and discharged from the process. BrüggemannAlcohol takes over these re-distillates from extraction manufacturers and, after various purification processes, uses them as raw alcohol for suitable purposes in order to produce alcohol of proven quality.
BrüggemannAlcohol obtains its raw materials mainly from Germany and to a lesser extent from neighbor EU countries. The latter are ideal suppliers because the short transport routes, with a low energy balance and reduced CO2 emissions, are part of the alcohol manufacturer's sustainability concept.
Due to the current pandemic, there has been a significantly higher need for disinfectants and this has increased the demand for alcohol enormously. Consequently, it is out of the question for BrüggemannAlcohol to obtain raw materials exclusively from the EU and not from third countries.
At BrüggemannAlcohol the long-term goal is to continuously improve the strategies and processes in terms of sustainability. What you always have to consider: Every single step counts in order to achieve great things!
