“…has been detected [2,[13][14][15][16][17][18][19][20][21]. Nevertheless, conventional WPCs with petroleum-based polymers, such as poly(ethylene)-PE, poly(propylene)-PP, poly(vinyl chloride)-PVC, and others have a negative impact during and at the end of the life cycle [22,23]. The use of WPCs is increasing in a remarkable way as they offer easy processing by conventional processing techniques (injection, extrusion, etc.…”

Poly(lactic acid), PLA‐based green composites were obtained with hazelnut shell flour (HSF) derived from the food industry thus leading to fully biodegradable materials with attracting properties. The hazelnut shell flour content varied in the 10–40 wt% range. An increase in the degree of crystallinity with increasing HSF was detected, mainly due to the nucleating effect of lignocellulosic particles. The thermodimensional stability was noticeably improved with increasing HSF amount as evidenced by a remarkable decrease in the coefficient of thermal–linear expansion. Increasing HSF leads to stiffer materials as HSF particles act as interlock points that restrict polymer chain motion. Addition of hazelnut shell flour as filler in PLA‐based green composites leads to fully biodegradable composites with balanced mechanical and thermal properties. Furthermore, it gives a solution to upgrade wastes from the hazelnut industry and contributes to lower the cost of PLA‐based materials. POLYM.

6 This study assesses the environmental impact of four alternatives for reinforcing 100 m 2 of 7 concrete footpath (Functional Unit, FU) by using cradle to gate life cycle assessment (LCA), 8 based on the Australian context. Specifically, the four options considered are a) producing 9 steel reinforcing mesh (SRM), b) producing virgin polypropylene (PP) fibre, c) recycling 10 industrial PP waste and d) recycling domestic PP waste. The FU yields 364 kg of SRM (in a) 11 and 40 kg of PP fibres (in b, c and d), necessary to achieve the same degree of reinforcing in 12 concrete. All the activities required to produce these materials are considered in the study, 13 namely manufacturing and transportation, and also recycling and reprocessing in the case of 14 industrial and domestic recycled PP waste fibres. These processes are individually analysed 15 and quantified in terms of material consumption, water use, and emissions into the 16 environment. This allows for the impacts from producing recycled fibres to be compared 17 with those from producing virgin PP fibre and SRM, which are traditionally used. The LCA 18 results show that industrial recycled PP fibre offers important environmental benefits over 19 virgin PP fibre. Specifically, the industrial recycled PP fibre can save 50 % of CO 2 equivalent, 20 65 % of PO 4 equivalent, 29 % of water and 78 % of oil equivalent, compared to the virgin PP 21 fibre. When compared to the SRM, the industrial recycled PP fibre can save 93 % of CO 2 22 equivalent, 97 % of PO 4 equivalent, 99 % of water and 91 % of oil equivalent. The domestic 23 M A N U S C R I P T A C C E P T E D ACCEPTED MANUSCRIPT2 recycled PP fibre also generates reduced environmental impacts compared to virgin PP fibre, 24 except for higher consumption of water associated with the washing processes. 25

Materials used in the exterior of buildings and in construction are routinely exposed to solar UV radiation. Especially in the case of wood and plastic building materials, the service life is determined by their weather-induced deterioration. Any further increase in ground-level solar UV radiation, UV-B radiation in particular, will therefore reduce the outdoor service life of these products. Any increase in ambient temperature due to climate change will also have the same effect. However, the existing light-stabilizer technologies are likely to be able to mitigate the additional damaging effects due to increased solar UV radiation and maintain the outdoor lifetimes of these materials at the present levels. These mitigation choices invariably increase the lifetime cost of these products. A reliable estimate of what this additional cost might be for different products is not available at the present time. Personal exposure to UV radiation is reduced both by clothing fabrics and glass windows used in buildings and automobiles. This assessment describes how the recent technical advances in degradation and stabilization techniques impact the lifetimes of plastics and wood products routinely exposed to solar UV radiation and the protection to humans offered by materials against solar UV radiation.
