Este projeto pretende estudar e definir o processo de produção a escala industrial, de um açúcar raro, a alulose, na COPAM. Para tal, foi realizada uma extensa revisão bibliográfica, que permitiu a definição do produto e a perceção do seu estado atual na indústria dos açúcares, e em especial na União Europeia, seguido de uma análise de viabilidade económica de vários cenários do projeto na empresa.
A alulose é um açúcar raro, com baixo teor calórico (0,4 cal/g) que se destaca no mercado devido ao seu sabor e benefícios para a saúde em comparação aos açúcares convencionais.
Foram estudados 4 cenários para a implementação do xarope de alulose na COPAM, considerando 2 matérias-primas diferentes. O cenário 1 e o cenário 4 utilizam isoglucose, produzida pela empresa, e apresentam um consumo específico igual de 3,8 ton/ton. A diferença entre os mesmos é a capacidade instalada, o cenário 1 utiliza toda a capacidade de isoglucose, 79 ton/dia, e o cenário 4 utiliza metade, com o restante a ser vendido. Os cenários 2 e 3, utilizam a frutose sólida com um consumo específico de 4,3 ton/ton. O cenário 2 tem a mesma capacidade que o cenário 1, e o cenário 3 é um teste à sensibilidade do efeito de escala, com o dobro da capacidade do cenário 2.
Os resultados evidenciaram que o cenário mais viável seria o cenário 1, visto que apresenta os melhores indicadores de rentabilidade, menor risco de negócio e melhor margem bruta. Para este cenário a capacidade anual de produção do xarope seria de cerca de 7 kton, com um custo unitário de fabrico de 1 945 €/ton, para um investimento total de 23 milhões de euros. Em termos dos indicadores de rentabilidade, o cenário 1 apresenta uma VAL de 7 milhões de euros, uma TIR de 13% para uma taxa de atualização de 8% e um período de recuperação de capital de 4 anos e 11 meses.
As análises de sensibilidade indicaram que a margem bruta é a variável mais crítica para a viabilidade económica, com um aumento de 10% nessa margem a resultar em variações significativas na VAL (57%) e na TIR (23%). Deste modo, conclui-se que o risco do mercado é uma prioridade no planeamento do desenvolvimento do projeto.
Em suma, a produção deste açúcar raro na COPAM, apresenta uma oportunidade para a empresa se destacar no mercado dos adoçantes, podendo vir a ser pioneira no fabrico deste produto na Europa.
This project aims to study and define the process of producing a rare sugar, allulose, on an industrial scale at COPAM. To this end, an extensive literature review was carried out to define the product and understand its status in the sugar industry, especially in the European Union, followed by an economic feasibility analysis of various project scenarios at the company. Allulose is a rare, low-calorie sugar (0,4 cal/g) that stands out on the market due to its flavour and health benefits compared to conventional sugars. Four scenarios were studied for the implementation of allulose syrup at COPAM, considering two different raw materials. Scenario 1 and scenario 4 use isoglucose, produced by the company, and have an equal specific consumption of 3,8 ton/ton. The difference between them is the installed capacity: scenario 1 uses all the isoglucose capacity, 79 ton/day, and scenario 4 uses half, with the rest to be sold. Scenarios 2 and 3 use solid fructose with a specific consumption of 4,3 ton/ton. Scenario 2 has the same capacity as scenario 1, and scenario 3 is a test of the sensitivity of the scale effect, with twice the capacity of scenario 2. The results showed that the most viable scenario would be scenario 1, as it has the best profitability indicators, the lowest business risk, and the best gross margin. For this scenario, the annual syrup production capacity would be around 7 kton, with a unit manufacturing cost of 1,945 €/ton, for a total investment of 23 million euros. In terms of profitability indicators, scenario 1 shows a VAL of 7 million euros, an TIR of 13% for an 8% discount rate and a payback period of 4 years and 11 months. The sensitivity analyses indicated that the gross margin is the most critical variable for economic viability, with a 10% increase in this margin resulting in significant variations in VAL (57%) and TIR (23%). It can therefore be concluded that market risk is a priority when planning the development of the project. To summarise, the production of this rare sugar at COPAM presents an opportunity for the company to stand out in the sweeteners market and could become a pioneer in the manufacture of this product in Europe.
