“…Thus, in the near future, the certified organic product, like the industrial product with an eco-label, can from an LCA, obtain the organic seal (PIRES et al, 2002). In Brazil, there is still little research with the LCA approach; however, the issue is emerging and has been gaining ground due to society's growing concern about sustainable, socially-just and economically-viable productive practices (CLAUDINO, TALAMINI, 2013).…”

The assessment of energy efficiency (EE) and greenhouse gas (GHG) emissions can highlight the sustainability of agro-systems and decision-making regarding reduction of production costs and environmental pollution. In this context, the objective of this work was to evaluate the EE and GHG emissions (CO 2 , CH 4 e N 2 O) of a soybean crop under organic cultivation in different regions of Brazil in the agricultural year 2014-2015. For this, 19 soybean areas were evaluated. The inputs and outputs of the agricultural operations and / or inputs used were calculated by multiplying the quantity used by their calorific value or energy coefficient at each stage of production. The energy efficiency was obtained by the ratio between the amount of total output energy and the total energy consumption during the production process. In order to estimate GHG emissions, the principles of the life cycle assessment methodology and recommendations of the Intergovernmental Panel on Climate Change (IPCC) were applied. For each 1.0 MJ of energy consumed in the organic production of soybeans, an average of 7.9 MJ of renewable energy was produced in the form of grains of this crop. The main energy costs of growing these organic crops were with seeds, fuel and with tractors, machines and agricultural implements (TMI). For each 1 kg of organic grain produced from soybeans, 0.19 kg of CO 2 eq are emitted during their production and delivery cycles in the warehouse. The main sources of CO 2 eq emission to the atmosphere were the seeds, fuels and organic fertilizers.

“…Apesar disso, as tendências nas sociedades de consumo atuais mostram a preferência das pessoas pela valorização da alimentação fora de casa e com isso, muitas vezes, a desestruturação das refeições, mas também a valorização do natural, bem como a preocupação com a saúde e o equilíbrio alimentar (PROENÇA, 2010). Mas a indústria de alimentos é também responsável por impactos ambientais negativos (PERIGNON et al 2017), com ou sem a inovação, já que o agronegócio está entre os principais agentes de geração de resíduos sólidos (CLAUDINO;TALAMINI, 2013). Esses resíduos apresentam elevada concentração em carbono e nitrogênio, considerando as distintas atividades vinculadas à produção e à transformação de produtos agropecuários .…”

RESUMOCom o crescimento populacional e o desenvolvimento industrial e tecnológico, a produção de resíduos sólidos tem aumentado consideravelmente ao longo das últimas décadas, acentuando a discussão sobre sustentabilidade e a adequada destinação desses resíduos. Um dos setores responsáveis pela geração de grande quantidade de resíduos sólidos são as agroindústrias, tais como a de processamento de palmito, que é bastante difundida no Brasil e regiões tropicais. Para abordar essa problemática, este trabalho de revisão visa mostrar a importância da agroindústria de palmeiras comestíveis, seus impactos ambientais e sociais, e apresentar uma proposta de inovação para a indústria de alimentos funcionais, por meio de uma pesquisa descritiva qualitativa. A inovação apresentada nesse trabalho está relacionada com a aplicação da biotecnologia pela utilização das cascas ou bainhas medianas de palmeiras que são geradas durante a produção de palmito em conserva ácida, para o cultivo de fungos. Essas cascas quando empregadas como substrato para produção de cogumelos comestíveis poderá resultar em um alimento funcional, rico em nutrientes e com benefícios à saúde do consumidor, já que contêm moléculas bioativas, tais como as β-glucanas. A possibilidade de comercialização desse alimento, poderá resultar em benefícios socioambientais pelo aumento de renda dos envolvidos e pela redução de um passivo ambiental.Palavras-chave: Alimento funcional. Biotecnologia. Cogumelos. Resíduos agroindustriais.

“…The adoption of new production technologies made it possible for Brazil to stand out as a major food world supplier, but the search for sustainability is one of many new challenges, as the global market asks for products with reduced environmental impact (Claudino and Talamini 2013). Life Cycle Assessment (LCA) is a great tool to assess agricultural product environmental performance.…”

Sunflower is an important crop in Parecis region of the Brazilian Cerrado. In 2014, the region produced 232.700 tons of sunflower grains, 45% ofthe national production. Sunflower production comes mostly from a system that has soybean as the main crop. The association of soybean and sunflower can reduce environmental impacts due to shared use of resources. This study performed a "cradle to gate" Life Cycle Assessment (LCA) of the soybean-sunflower production system used in Parecis region and compared its environmental profile to that of the monoculture of these two crops. We evaluated the impacts related to the use of soil (land use change emissions and liming) for each crop according to three allocation criteria: time of soil occupation, yield and gross margin. Although performance on "Climate Change" and some other impact categories had varied according to the allocation criteria used, the soybean-sunflower rotation crop system presented lower environmental impacts on every category when compared to soybean and sunflower monocultures with the same yield. Important impact reductionswere observed on "Climate change" (43%), "Terrestrial acidification" (26%) and "Particulate matter formation" (20%) categories.
