Urban forestry generates a huge amount of waste worldwide, resulting from the processes of pruning and suppression. Disposal in landfills reduces the useful life of these facilities and forgoes the possibility of generating income from the waste. This study investigated the manufacture of toys as a strategy to valorize urban forestry waste. For this, physical-mechanical, chemical (extractive), color and shape characterizations were performed for three species of urban trees commonly planted in Brazil, a region of Neotropical forests. Toy prototypes were developed and manufactured from wood waste. Regarding color, all studied species showed high value of the variable b*, which refers to the blue-yellow axis. Handroanthus heptaphyllus wood had the highest values of basic density (0.706 g.cm-3) and Janka hardness (1142, 1027 and 1669 kgf.cm-2 for radial, tangential and transverse directions, respectively), and had the lowest volumetric shrinkage (11.38%). The lowest content of total extractives was measured in Handroanthus heptaphyllus, 6.33%, and the greatest content was found in Spathodea campanulata, 7.01%. The average value suggested for the toy prototypes varied between $ 3.70 and $ 13.58. The urban pruning wastes of the species studied have physical, chemical and mechanical attributes suitable for the manufacture of toys. This use has strong potential for environmental, economic and social sustainability and the toys are pedagogically accepted by adults and children.
