RESUMO:

Among the most typical species in the Amazon region, the Euterpe oleracea Mart palm., commonly known as açaí, stands out because of the numerous forms of fruit consumption. The pulping is carried out by hand usually by "beaters" and the high cost of disposal of the waste generated in large quantities it is a major production limitation. The objective of this study was to verify if the geoinformation is able to assist in the subdivision of the neighborhoods of the city of Belém regarding the generation of waste by certified mixers and as much as the amount of stored energy. A quantitative survey on the number of commercial establishments certified with the seal "Acai Good" by the municipal government of Belém. In order to obtain the geographical coordinates of all mixers, a model GARMIN GPS GPSmap 62sc configured to UTM/SIRGAS 2000 coordinates was used. A minimum sample number of establishments for the collection and characterization of waste subdivided depending on the type of mixer, beater experience and mixer location has been set. The determined properties of the waste were moisture content and the contents of volatiles, fixed carbon and ashes for estimating the higher heating value. From the determination of the residual mass contained in a can, the waste factor generation and the daily production range, equations for quantifying the minimum and maximum values of generated waste weekly during the crop season and off-season were proposed. For the generation of maps, it was used ArcGIS 10.1 software in images obtained from Landsat 8 the year 2018. Within the software integration it was carried out of the "shapes" of delimiting the municipality of Belém and the data concerning the coordinates of the mixers, thus generating the location of beater map. It was found that the newly processed wastes have a high moisture content (79.48%) and when dried had a mean useful higher heating value of 2952.72 kcal/kg. During the crop season, each artisan beater generates 485.10 kg to 646.80 kg of açaí waste per week, therefore it is necessary grouping of 10-14 establishments to supply one gasifier during one week. In the inter-crop season, the beaters generate 323.40 to 388.08 Kg of waste, thus requiring a larger grouping, 17 to 21 mixers. The neighborhoods of the Umarizal (693-924 kg) Quarry (554.4 to 739.2 kg) and Condor and Marco (485.1 to 646.8 kg) generated the greater amount of waste per day. Condor and Marco and Umarizal have more energy stored in the açaí waste with 0205 TEP/day. The use of geoinformation is able to assist in the division of the display neighborhoods to both poles of waste generators and for poles with large amounts of stored energy.
