Life Cycle Assessment of Concrete Masonry Units with Waste Paper Fibres

Renewable or recycled materials have been widely used in the construction industry to achieve a sustainable target. As a kind of short cellulose fibre, a massive amount of waste paper fibre was generated annually from the industrial and construction sectors. However, the research on the use of waste paper fibres in construction/building materials is limited. The feasibility and sustainability of papercrete used as a building material were investigated based on a Life Cycle Assessment (LCA) method by analysing its characteristics compared to four production scenarios. LCA results demonstrate waste paper fibres used as the cement substitute in concrete benefit to reduce the environmental impact compared to traditional disposal.
