Wood waste generated in carpentry workshops in the municipality of Camoapa

Abstract

The wood construction industry generates large volumes of waste such as rubble, colocho, sawdust, etc., which are not being used since with them we can make or finish a certain product, by virtue of throwing them away, burning them or selling them. The purpose of the study is to characterize the wood waste generated in carpentry workshops in the municipality of Camoapa. The research was of a non-experimental type, for the collection and analysis of primary information, a semi-structured survey was applied to the owners of ten carpentry workshops. The variables evaluated were: wood residues, use of residues and alternatives for use. The data were analyzed using frequency distribution and histograms, for the design of alternatives the SWOT matrix (Weaknesses, Threats, Strengths, Opportunities). It was found that the types of wood waste generated are sawdust in greater quantity, dust, cuttings and colochos in a smaller percentage, they are collected weekly and sometimes daily. The volume of waste generated per cleaning time ranges between 2 kg and 9 kg. 60 % of the workshops make a selection of the waste produced, those who do not argue that they cannot waste their time in this task. 50 % of the carpentry workshops use the waste to complement pieces of other products, on the other hand, the other percentage sell it to housewives and stables. The sale prices range from USD 0.031 a USD 0.093 per kg. 90 % of the owners of carpentry shops said they were interested in being trained to take advantage of wood waste. In conclusion, the waste generated in the carpentry workshops is not used, there is no selection and storage, they are all mixed in one place. An alternative is to use them to make by-products, from a business perspective that generates foreign exchange and reduces production costs.
