This paper discusses possible health implications related to dust particles released during the manufacture of sheep's wool-based non-woven insulation material. Such insulation may replace traditional synthetic insulation products used in roofs, wall cavities, etc. A review of the literature concerning organic dusts in general and sheep's wool fiber summarizes dust exposure patterns, toxicological pathways and the hazards imposed by inhalation and explosion risk. This paper highlights a need for more research in order to refrain from overgeneralizing potential pulmonary and carcinogenic risks across the industries. Variables existing between industries such as the use of different wool types, processes, and additives are shown to have varying health effects. Within the final section of the paper, the health issues raised are compared with those that have been extensively documented for the rock and glass wool industries.

Single-use plastic packaging is a cause of rising environmental concerns due to high production volumes, short usage time, and problems related to end of life management and release into the environment. As a result, there is an increased demand to develop alternative non-plastic packaging from agricultural waste materials. This paper reported findings for converting, via atmospheric refining, waste oil palm empty fruit bunch (EFB) fibres into a fibrous pulp which can then be used to produce three-dimensional pulp moulded products. By optimising the mould design, the efficiency of vacuum suction was improved, which in turn helped to improve fibre distribution and the quality of moulded trays; such moulded trays are suitable for the containment of food items such as fruit and vegetables. Furthermore, when combined with compostable barrier treatments, lidding and adhesive films currently under development, there is an opportunity to provide a complete biocompostable packaging solution for some food items. Furthermore, as these pulp moulded packaging products are made from agricultural fibre wastes rather than plastics, the pulp moulded trays are recyclable or compostable at the end of life. Therefore, if a release does occur into the environment, it would not persist.
