Uisa quer tornar seu etanol carbono negativo

  • Spanish Market: Biofuels, Emissions
  • 21/09/23

A Uisa, empresa sucroalcooleira da região Centro-Oeste, aposta na evolução dos mercados de carbono e na importância das credenciais de sustentabilidade do agronegócio para expandir seus negócios.

O projeto de captura e armazenamento de carbono da companhia pela rota da bioenergia (BECCS, na sigla em inglês) está ganhando tração: a Uisa planeja injetar o carbono da produção de etanol em Nova Olímpia (MT), na Bacia Sedimentar do Parecis.

Com a inevitabilidade da precificação do carbono, a produção com emissão negativa de gases de efeito estufa (GHG, na sigla em inglês) pode tornar o biocombustível da companhia ainda mais competitivo no mercado internacional.

Em entrevista à Argus, Caetano Grossi, gerente de sustentabilidade da empresa, fala sobre a iniciativa e os próximos passos para a estruturação do mercado de carbono no país. A seguir, os principais trechos da conversa.

Como o carbono pode agregar valor para uma usina sucroalcooleira?

Temos uma ampla gama de projetos e iniciativas voltadas para a neutralização de CO2, com intuito de melhorar a nossa nota de eficiência no contexto da Política Nacional de Biocombustíveis (Renovabio) e, consequentemente, a geração de Cbios. Hoje, essa é a terceira maior receita da companhia, atrás apenas do açúcar e do etanol.

Mas, a Uisa também trabalha em iniciativas nessa área para além do Renovabio, como a geração de créditos de carbono vinculados a áreas de reserva legal, por exemplo. O próximo passo é o BECCS.

O que o BECCS vai proporcionar?

O processo de fermentação para a fabricação do etanol gera CO2, que é o mesmo que a cana capturou no campo através da fotossíntese. Esse carbono é devolvido para a atmosfera, então, ficamos empatados no zero a zero. São emissões consideradas biogênicas, naturais da própria cultura e que não penalizam a companhia.

Com o BECCS, conseguiremos capturar esse CO2 e devolvê-lo para o solo, ou seja, teremos emissões negativas. Ao invés de descartar, vamos capturar o carbono e injetá-lo no solo.

A tecnologia não é nova, é similar ao que é amplamente usado na indústria de óleo e gás, inclusive pela Petrobras. Estamos fazendo um estudo geológico e sísmico dentro de uma área de interesse próxima da nossa companhia para identificar o local adequado de perfuração do poço, que deve ter entre 2.000-2.500m de profundidade.

As condições são similares ao projeto anunciado pela FS?

Eles são bem similares. Uma diferença é que o nosso poço ficará a cerca de 20km de distância da planta industrial, então teremos que construir um gasoduto para transportar o CO2 comprimido para o ponto de injeção. Já o poço da FS ficou praticamente dentro da planta.

No mês passado, fiz uma visita à planta da ADM, em Illinois, nos Estados Unidos, que atingiu capacidade de injetar 1.000t de CO2 por dia. A nossa previsão é de injetar até 2.000t de CO2 por dia, porque o nosso volume de produção de etanol é bastante significativo.

Quais são os mercados cativos para esse etanol com pegada negativa de CO2? A indústria do combustível de aviação sustentável (SAF, na sigla em inglês)?

Sim, exatamente. Com a expansão do etanol de milho no Brasil, particularmente aqui no Mato Grosso, acredito que as biorrefinarias priorizarão a produção de açúcar para o mercado interno e buscarão novas linhas de comercialização para o etanol, tanto para a indústria do SAF quanto para o mercado europeu de combustíveis, onde o apelo ambiental do carbono negativo é muito maior.

Já somos certificados pelo Conselho de Qualidade do Ar do Estado da Califórnia [CARB] para exportar etanol combustível sob o Padrão de Combustível de Baixa Emissão de Carbono [LCFS] do estado.

No contexto do SAF, o etanol precisa ser certificado para ser usado como matéria-prima, que é o que estamos buscando hoje com a Certificação Internacional em Sustentabilidade e Carbono [ISCC Corsia Plus].

A construção de uma planta de etanol de milho foi um dos primeiros projetos anunciados após a reestruturação da Uisa, em 2019. Como se encontra esse projeto?

Já temos as licenças prévia e de instalação emitidas pela Secretaria de Estado Meio Ambiente (Sema), porém, no decorrer do processo, nosso foco principal se voltou para a questão da descarbonização.

A companhia optou por priorizar outros projetos – construiu uma unidade industrial de produção de biometano e biogás, iniciou a operação da fábrica de leveduras, aumentou a capacidade de cogeração e transmissão de energia, entre outros. Buscamos alternativas para agregar o máximo de valor e produtos possíveis na cadeia de produção de cana-de-açúcar e o milho ficou um pouco para trás.

Nossa previsão é retomar a instalação dessa da planta de milho em 2025. Ela será integrada à planta de cana-de-açúcar, contando com a biomassa do bagaço para alimentar a operação.

Quais outras tendências estão no radar da companhia hoje?

A venda da biomassa de bagaço de cana-de-açúcar para as usinas de milho virou uma boa fonte de receita para a Uisa. Essas plantas nos ajudaram a eliminar esse passivo ambiental, porque nossa geração de bagaço era muito farta e, atualmente, conseguimos comercializá-lo.

NYC comptroller sets net zero investment standards

NYC comptroller sets net zero investment standards

Houston, 25 April (Argus) — New York City's top financial officer this week issued standards that will be used to evaluate investment plans for the city's retirement systems that aim to meet net zero goals. Comptroller Brad Lander adopted a "Net Zero Implementation Plan" in 2022 requiring public markets asset managers, who manage funds for New York City's retirement systems, to submit investment plans that work towards achieving net zero by 2040 to his office by 30 June. Earlier this month, his office announced that the city's pension systems lowered their greenhouse gas (GHG) emissions by 37pc and achieved their interim climate goals one year early , with much of that decline driven by divestment of fossil fuel reserve owners. Under the standards released on 22 April, asset managers should take into account climate-related investment risks in their decision-making and work with portfolio companies to promote "real economy decarbonization." In addition, asset managers must require portfolio companies to report and set goals to reduce their scope 1 and 2 emissions — direct emissions from sources owned by the company and from electricity purchases, respectively — as well as scope 3 emissions, or indirect supply chain emissions. Investment plans must also include short-, medium-, and long-term goals to reach net zero and ensure that future capital expenditures and lobbying align with those goals. For plans that do not meet those standards, Lander will recommend to "put those managers' investment mandates out to bid , " or begin a lengthy procurement process to contract new asset managers to manage those funds. "Our new standards demand that the retirement systems' managers strengthen their Net Zero plans consistent with their fiduciary duty — or we will find new asset managers who will," Lander said. The New York City Comptroller oversees five public pension funds which together form the fourth largest public pension plan in the US, with about $285bn in assets that are managed by external investment managers contracted by the city. Lander said that threats from the federal government, including efforts to halt offshore wind , as well as President Donald Trump's executive order targeting state and local climate policy, would affect the city's ability to lower emissions and were a major reason for issuing the net zero standards. New York City's pension systems have goals of investing $1.8-19bn in "climate change solutions" by 2035.

Brazilian wildfires burn 70pc less area in 1Q

Sao Paulo, 23 April (Argus) — Wildfires in Brazil scorched an area almost equivalent to the size of Cyprus in January-March, but still 70pc less than in the same period in 2024 as the rainy season was above average in most of the north-central part of the country this year. The wildfires spread out over 912,900 hectares (ha) in the first three months of 2025, down from 2.1mn ha in the same period of 2024, according to environmental network MapBiomas' fire monitor researching program. The reduced burnt areas are related to the rainy season in most of the country, but still-high wildfire levels in the Cerrado biome showed that specific strategies are necessary for each biome to prevent further climate-related impacts, researchers said. The Cerrado lost 91,700ha to wildfires in the first quarter, up by 12pc from a year before and more than double from the average since 2019. Burnt areas in the Atlantic forest also increased 18,800ha in the period, up by 7pc from a year earlier. Wildfire-damaged areas in the southern Pampa biome, or low grasslands, grew by 1.4pc to 6,600ha. The Amazon biome lost over 774,000ha to wildfires in the first quarter of 2025, a 72pc drop from a year earlier, while it accounted for almost 52pc of burnt areas in March. The loss represented 84pc of the total burnt land in the period. Burnt areas in the central-western Pantanal biome, or tropical wetland, fell by 86pc in the first quarter to 10,900ha. The northeastern Caatinga biome, or seasonally dry tropical forest, lost around 10,000ha in burnt areas, down by 8pc from the same period in 2024. Reductions may not persist as a drought season will begin in May and is expected to be severe, according to Mapbiomas. Last year, an extended drought season prompted burnt areas to grow by 79pc from 2023. Northern Roraima state was the state to suffer the most from wildfires in the period, with 415,700ha lost to wildfires during its distinct drought season in the beginning of the year, while other states faced a rainy season. Northern Para and northeastern Maranhao followed, with 208,600ha and 123,800ha of burnt areas, respectively. Wildfires hit over 24,730ha of soybean fields in the period, a 29pc decrease from a year earlier, while burnt areas in sugarcane fields fell by 31pc to around 7,280ha. Wildfires hit 106,600ha of the country in March, a 86pc decrease from 674,900ha a year earlier.

US wants IMF, World Bank to drop climate focus

Washington, 23 April (Argus) — US president Donald Trump's administration today called on the IMF and the World Bank to focus resources away from climate action and energy transition and to make lending available to fossil fuels programs. The IMF "devotes disproportionate time and resources to work on climate change, gender, and social issues," US treasury secretary Scott Bessent said in remarks today timed to coincide with the two international lending institutions' annual meeting in Washington. "Like the IMF, the World Bank must be made fit for purpose again," he said, during an event hosted by trade group Institute of International Finance. The IMF and the World Bank in recent years have followed the preferences of their largest shareholders — the US and European countries — in incorporating the effects of climate change in their analysis and to facilitate energy transition in the emerging economies. The World Bank, together with other multilateral development banks globally, announced at the UN Cop-29 climate conference last year that they could increase climate financing to $170bn/yr by 2030, up from $125bn in 2023. "I know 'sustainability' is a popular term around here," Bessent said. "But I'm not talking about climate change or carbon footprints. I'm talking about economic and financial sustainability." Bessent urged the World Bank to "be tech neutral and prioritize affordability and energy investment," adding that "in most cases, this means investing in gas and other fossil fuel based energy production." "In other cases, this may mean investing in renewable energy coupled with systems to help manage the intermittency of wind and solar," Bessent said. The US is the largest shareholder at both the IMF and the World Bank, with a 16pc stake in both institutions. The Trump administration, which has slashed climate programs at US government institutions and withdrew the US from climate-focused international efforts, has so far refrained from interfering in the operations of the IMF and the World Bank.

EU will submit climate plan ‘in time’ for September

Brussels, 23 April (Argus) — The European Commission aims to present the bloc's new climate plan "in time" for a synthesis report being prepared by UN climate body the UNFCCC in September. Signatories to the Paris climate agreement commit to submitting climate plans, known as nationally determined contributions (NDCs), every five years. The current round should outline emissions reduction plans up to 2035. "We need to be able to submit the EU's NDC in time for the synthesis report that the UN will produce in September," director general of the commission's climate action directorate Kurt Vandenberghe said. Speaking to the European Parliament's environment committee Vandenberghe said there is still "increasing interest" around the world to work on a global climate deal, despite the US pulling out of the Paris agreement. Vandenberghe also noted a "very co-operative" China at the UN Cop 29 climate summit in Baku, Azerbaijan, in November 2024. China reiterated today that it would submit an NDC that covered all economic sectors and all greenhouse gases . European Commission president Ursula von der Leyen and European Council president Antonio Costa participated in the same meeting today, convened by the UN and Brazil's president Luiz Inacio Lula da Silva. "China is increasingly committing on a voluntary basis to contribute climate finance to the developing world," Vandenberghe said, even as Beijing seeks to retain its status as a "developing" nation. Countries classed as developed by the UNFCCC are expected to deliver climate finance to developing nations. The EU has yet to officially propose a 2040 climate target . It plans to derive its 2035 goal, which will form the basis of its NDC, from this. Presenting a 2040 EU CO2 target in September is the right time for German centre-right EPP member Peter Liese. But a 90pc greenhouse gas (GHG) reduction target for 2040 is "really, really ambitious". "I would have preferred a lower target. But we are where we are," Liese said, calling for flexibility for the EU's 2040 GHG reduction target and support for global trading of carbon credits. "We need this 90pc target. We are open to discuss flexibilities, but we need this target to give predictability to our companies, also because it is our economic interest," French liberal and a former chair of the environment committee Pascal Canfin said.

Bio-bunker sales in Rotterdam down in 1Q

Bio-bunker sales in Rotterdam down in 1Q

London, 23 April (Argus) — Sales of marine biodiesel blends in Rotterdam fell for the third consecutive quarter in January-March as demand shifted east of Suez. Port data for the first quarter of 2025 show marine biodiesel blend sales declined by 12pc compared with the previous three months and by 60pc compared with the same period last year. The decline was underpinned by lower prices in Singapore. B24 dob Singapore — a blend comprising very low sulphur fuel oil (VLSFO) and used cooking oil methyl ester (Ucome) — averaged a $36/t discount against B30 advanced fatty acid methyl ester (Fame) 0 dob ARA in the first quarter, and a $129.74/t discount against B30 Ucome dob ARA. This price dynamic made Singapore an attractive bunker hub for those shipowners opting to use biodiesel blends to help their customers meet sustainability goals. It also attracted demand from shipowners bound by the FuelEU maritime regulations introduced in January this year. The regulations require a reduction in greenhouse gas (GHG) emissions from ships travelling into, out of and within EU waters, but energy consumed from blends bunkered in Singapore can be mass balanced to be fully accounted for under the scope of the rules. A pooling mechanism within the regulations also allows vessels operating on the east-west route to utilise compliance generated from marine biodiesel blends bunkered in Singapore across other ships that operate solely in Europe. While biodiesel bunker sales in Rotterdam fell, biomethanol sales at the port soared almost sixfold in January-March compared with a year earlier. The sharp rise in demand reflects the rollout of FuelEU Maritime , higher mandates in Europe for the use of renewables in transport this year and changes to regulations on the carryover of renewable fuels tickets in Germany and the Netherlands . Sales of conventional bunker fuels in Rotterdam edged up by a more modest 1pc on the quarter and by 7pc on the year. Sales of high-sulphur fuel oil (HSFO) overtook those of very low sulphur fuel oil (VLSFO), reversing the trend of the previous quarter despite the imminent addition of the Mediterranean Sea as an Emission Control Area (ECA). Ships without scrubbers that sail through ECA zones must use fuels with a maximum sulphur content of 0.1pc, such as marine gasoil (MGO) and ultra low sulphur fuiel oil (ULSFO). LNG bunker sales in Rotterdam fell by the 13pc on the quarter in January-March, reflecting a price rally at the Dutch TTF gas hub in late January and early February. The Argus northwest Europe LNG bunker price stood at a two-year high of €64.35/MWh on 6 February. LNG bunker sales were still higher than in the first quarter last year, which likely stems from the introduction of the FuelEU Maritime regulations.
