As usual, this paper reports on the last calendar year. For Profertil, 2021 was a year of enormous challenges, where one of the main players was the plant turnaround we had during the winter: it was the longest in our history and allowed us to conduct key works to increase the reliability of the Ingeniero White production facilities. In these lines it is worth acknowledging and congratulating the work team involved, who managed to complete it on time and in a timely manner, with excellent technical, safety and environmental results.
In addition, 2021 was the year of our twentieth anniversary. How proud each one of us is to be part of a first-class company with such a rich history. That is why we took advantage of it to leverage our commitment to the transformation of the industry towards sustainable agriculture. A cross-cutting group from all our divisions formed the Sustainability Team and is working hard in line with the SDGs prioritized by Profertil.
We have taken many steps in this direction and a milestone in 2021 was that we reached 60% of electricity supply from renewable sources at our Bahia Blanca Plant. This number is well above the 16% required by Act No. 27,191 for this year.
We cannot talk about the past year without remembering that we are still in a pandemic scenario, so the challenges for the work team were many and strong. The organization continued to work with hybrid schemes, with employees who continued with their tasks from home and others who, with the necessary care and protocols, continued to operate the plants and terminals in person. Our industry was declared essential by the National Government, so we had to redouble our efforts to continue working. The technology and procedures that were applied for this care were the subject of congratulations from fellow companies, our Port and governmental entities.
Our company, with more than 20 years of responsible and professional work, reached another important milestone in 2021: for the first time it placed negotiable bonds in the local market. With a total demand of USD 41 million, the bond issue reached USD 25 million (USD 5 million more than expected) through the dollar link instrument, at a rate of 2.49% and with a maturity of 24 months. The amount of the offering will be used to increase fertilizer production, to provide the Company with working capital and to reinforce the sustainability of the production complex. This issuance placed us at a new level, which demonstrates the professionalism and transparency with which our Company is managed, and of which we can be proud.
In addition, in a path that is necessarily intersected by technology and digitalization, together with the Rosario Stock Exchange (BCR) we launched the fertilizer module of the Muvin logistics app, which we currently use to manage the distribution of our products throughout the country. This work carried out by Profertil, thinking beyond its production stages, seeks to reach the entire product chain, benefiting the entire industry. This alliance is oriented to fertilizer logistics, where the protagonists are the customers, cargo terminals and transporters, key players in the commercialization of nutrients. With them, we constantly emphasize the importance of best agronomic management practices in the pursuit of sustainable agriculture.
From now on, our Sustainability Report will report with SASB indicators. A new standard that allows us to identify the main sustainability issues that directly impact our type of industry. These indicators will guide us towards what will be a new stage in our journey, when we reach the ESG Report (environment, society and governance), always thinking about deepening the proactive and forward-looking look of our work.
I really hope you enjoy this report. Not only because it is carried out with great dedication by a great work team, but especially because I am confident that you will find here extremely valuable information that shows how we do things, how we see the historic times ahead and how, day by day and from our individual places, all of us who make up Profertil are committed to sustainable industry and agriculture.
