Biomass pyrolysis transforms residual organic materials (agricultural, forestry or municipal) into value-added products such as biooil, biochar and gases. While bio-oil has attracted the attention of researchers and industry as a potential substitute for petroleum feedstocks, recent attention has been expanded to biochar. Biochar is a relatively porous carbon-based material including the mineral content of the original biomass. Its physical characteristics include light weight, excellent insulating properties, adsorption capacity for moisture and pollutants, protection from radiation, as well as carbon sequestration. The proposed research focuses on the exploitation of biochar properties which could make it as an attractive material to incorporate in green building materials. The overall objectives include both qualitative and quantitative characterization of the addition of different proportions of biochar to samples of plaster and of concrete bricks/blocks in terms of (a) mechanical properties and durability, including weight and compressive strength, (b) curing time, (c) moisture retention and control, (d) carbon sequestration potential, (e) acoustic properties including sound absorption and sound transmission loss, (f) thermal conductivity, (g) freeze-thaw weathering, and (h) odors/pollutants adsorption properties.

生物质热解将残留的有机材料（农业、林业或市政）转化为生物油、生物炭和气体等增值产品。虽然生物油作为石油原料的潜在替代品吸引了研究人员和工业界的注意，但最近的注意力已扩展到生物炭。生物炭是一种相对多孔的碳基材料，包括原始生物质的矿物质含量。它的物理特性包括重量轻，绝缘性能优异，对水分和污染物的吸附能力，防辐射以及碳封存。拟议的研究重点是开发生物炭的特性，这可能使其成为一种有吸引力的材料，纳入绿色建筑材料。总体目标包括在（a）机械性能和耐久性，包括重量和抗压强度，（B）固化时间，（c）水分保持和控制，（d）碳封存潜力，（e）声学性能，包括吸声和传声损失，（f）导热性，（g）冻融风化，和（h）气味/污染物吸附性能。
