Integration lean manufacturing and 6R to reduce wood waste in furniture company toward circular economy

Abstract

The furniture industry is suspected to have triggered global warming. The need for wood as raw material becomes a necessity for cutting down trees. The concept of a circular economy aims to reduce the use of natural resources by utilizing production waste or post-use product waste into raw materials. One strategy that can be used to support the circular economy is by implementing 6R. The application of 6R in a circular economic perspective on the furniture industry will be interesting to do. This study uses value stream mapping as a lean manufacturing analysis tool to identify furniture company waste. Value stream mapping is developed by integrating green manufacturing indicators such as material consumption and waste management. Practically, the furniture company can find out the map of production waste so that it can utilize waste as raw material for derivative products as an effort to reduce tree felling. Theoretically, this research will enrich the integration of green-value stream mapping toward the circular economy by implementing the 6R strategy in furniture companies. Reuse wood waste as a raw material for a variety of table products can reduce the amount of wood waste while reducing the resources of wood logs.

Circular economy-based product substitution design rationale: A case of personal care product

“…Several studies related to CE in the furniture industry have been conducted. Those studies include barriers and drivers (Barbaritano, Bravi & Savelli, 2019); challenges and opportunities (Oliveira, França & Rangel, 2018); business model (Wicaksono, Hartini, Sutrisno & Nabila, 2020); the relationship between environmental-oriented supply chain cooperation on the CE-targeted performances (Susanty, Tjahjono, and Sulistyani, 2020); and strategy to reduce wood waste (Hartini, Wicaksono, Rizal & Hamidi, 2021). Empirical studies of the potential waste from the furniture production process and the challenges of utilizing the waste in a circular economy are still rarely conducted.…”

New business models in the Circular Economy

“…Wood waste can occur at any stage in the production process, and also in the post-consumer phases of a product's life cycle. In the production phases, there are several types of wood waste (Hartini et al, 2021): timber harvesting waste, processing waste (sawmill dust, log cuts, veneer waste, peeled residues, and wood edge cutting). In the post-consumer phase, any broken or wornout piece of furniture can be considered wood waste that can be recycled into a myriad of products (Oliveira et al, 2018).…”

Upcycle strategy on tree branches to improve eco-efficiency towards a circular economy using life cycle assessment

“…Several studies on circular economy in the furniture industry have been carried out previously. There are investigations about Circular Economy practices, barriers, and drivers of CE [10]), the challenges and opportunities [11], the design of a business model [12], the relationship between varying ESCC practices on the CE-targeted performances [13], and the strategy to reduce wood waste [8]. Empirical studies of using tree waste as raw material for furniture products in a circular economy perspective are still rarely carried out.…”

“…Global furniture production in 2016 reached more than 99 million m^3 from 50 countries [6]), but only 40 to 60% of the total volume of raw wood is effectively used, and the rest becomes waste [7]. The burden faced by the traditional wood furniture industry is exacerbated by its inefficient production process resulting in a lot of wood waste [8]. On the other hand, the furniture industry that uses tree branches is starting to develop.…”
