Natalia Steblewska and Marta Stróżczyńska have received an honorable mention in the PLGBC Green Building Awards 2019 for their design of a synergistic coffee roasting plant. Congratulations!
Students from the Faculty of Architecture at Poznań University of Technology proposed using coffee grounds (a source of methane emissions that contribute to exacerbating the greenhouse effect) to produce energy in the design of a synergistic coffee roasting plant on the Warszawski estate in Poznań.
circular facility
The building proposed by the students, which uses coffee grounds to produce biofuel and pellets, was located in the green suburbs of Poznań. Wanting to preserve the natural character of the plot, the authors decided on a circular block overlooking a forest glade with a roof full of vegetation. The authors of the concept tried to take into account the whole cycle of the building's functioning: the construction process, operation and even its demolition.
The circular building is divided into parts: northern - technical with warehouses and delivery areas, southern and eastern - office with administration and customer zone (cafe and retail store), and western - intended for relaxation courtyard space with plenty of natural light.

The body of the factory is a reinforced concrete frame structure. The exterior walls were designed with TIM ( transparent insulation materials). Thanks to its transparency, the rooms in the building are adequately illuminated, without the need for additional window openings. The inner walls of the smoking room were designed from materials of natural origin - gray brick and natural cork, which can be reused after the building's operation.
The factory uses three sources of heat: from the ground (ground heat exchanger), from the sun (solar farm on the roof) and from burning pellets (waste from production). Water consumption has been reduced through the use of a gray water system and two rainwater tanks.
The factory is almost a self-sufficient facility

community project
The operation of the incinerator depends not only on large coffee consumers - restaurants or cafes - but also on the residents of Poznań, who can support the project by bringing in coffee waste from their own households. It is for them that the plant includes a café, an educational room and a recreational space.
The circular facility and its educational aspect were recognized by the jury of the PLGBC Green Building Awards 2019 with an honorable mention in the "Best Student Project" category.
