Abstract
A resource balance comprises a method to monitor sources and uses of a given material. The wood resource balance analyses origins of wood resources used in the production of semi finished forest products. At the same time, the resource balance helps tracking wood processing residues and its further uses. A primary survey with 113 companies was conducted and official statistics were consulted to carry out the first wood resource balance for Brazilian plantation forests. The balance sheets were analysed for 2008 and 2018. Wood resources consumption increased from 208 to 231 million m³. Wood processing residues volumes had grown by 19 % in the same period. Round wood demand for material use accounted to 66 % in 2018 whilst 99 % of residues were used energetically. The sector’s supply and production sides have shown to be in an exceptional balance. An increase on resource efficiency and cascading uses was observed in Brazil during the analysed period. The plantation forests supplied the greater domestic demand for round wood which relieves use pressure on natural forests.
Highlights
The monitoring of wood resources availability and its consumption is of great importance to maintain forest policy in balance with society needs
The round wood consumption increased by 7.2 % and reached almost 230 hm3 in 2018
The final sum of the wood resources consumption is higher since the wood resource balance (WRB) accounted volumes of wood processing residues (WPR), charcoal and pellets as wood sources too
Summary
The monitoring of wood resources availability and its consumption is of great importance to maintain forest policy in balance with society needs. The wood resource balance (WRB) methodology (Mantau et al, 2010) was conducted in several European countries to understand wood material flows and disclose competition between material and energy uses of wood. The cascading use strongly overlaps itself with the circular economy concept since describes actions to increase the resource efficiency and provides a comprehensive knowledge base for improvement in forest and related biobased industries(Jarre et al, 2020). The cascading use multiplies the benefit from one unit of resource if it is used as a material as long as possible and as a fuel only when further material utilisation is not possible or feasible(Taskhiri et al, 2019). Therfore the cascading use of wood is an important step to achieve sustainability
