The current fashion system uses high volumes of non-renewable resources to produce clothes, being responsible for 10% of the global greenhouse gas emissions into the atmosphere every year and 20%of the global water wasted. At the same time people are buying 60%more clothing than 15 Years ago, which going in the landfills, causes 92 million tons of waste each year. This waste has been further increased by the surgical masks used for COVID-19 pandemic. Thus, a new way of designing and producing clothing needs to be incorporated into the current system to facilitate its recycling making it more circular. New tissues, therefore, are proposed made by natural polysaccharides, embedded by micro- Nano capsules of chitin Nano fibrils and Nano lignin all obtained as by- products from food and forestry waste respectively. Thus, pollution and waste will be reduced and the natural raw materials will be maintained for the future generations.

The underground storage of greenhouse gases is seen by many as one of the primary technologies by which fossil fuel dependent nations can reduce their greenhouse gas emissions. Consequently there is a societal need to consider how best to facilitate the commercial scale uptake of this technology. Two principal barriers remain to the commercial scale deployment of greenhouse gas storage. Existing capture technologies are very expensive and there remains community concern that the underground storage of greenhouse gases is not permanent. It is likely that the natural gas industry will continue to be world leaders in the commercial-scale deployment of greenhouse gas storage, as this industry already captures large volumes of carbon dioxide and is familiar with underground storage technologies. In time, increased commercial scale deployment by the natural gas industry will build community confidence in the technology thus facilitating deployment by other industry sectors. Opportunities to promote greenhouse gas storage in Australia need to be considered in the broader policy context, which should be to reduce Australia’s greenhouse gas emissions at the lowest possible cost to the community. This extended abstract reviews the various ways in which greenhouse gas storage can be promoted and tests these in light of this broader policy context. The paper identifies those opportunities that should be pursued to promote the commercial scale uptake of greenhouse gas storage and flags those opportunities that, while they might assist in the uptake, are incompatible with the broader policy objective.

A “Well-to-Propeller” Life Cycle Assessment of maritime transport was performed with a European geographical focus. Four typical types of vessels with specific operational profiles were assessed: a container vessel and a tanker (both with 2-stroke engines), a passenger roll-on/roll-off (Ro-Pax) and a cruise vessel (both with 4-stroke engines). All main engines were dual fuel operated with Heavy Fuel Oil (HFO) or Liquefied Natural Gas (LNG). Alternative onshore and offshore fuel supply chains were considered. Primary energy use and greenhouse gas emissions were assessed. Raw material extraction was found to be the most impactful life cycle stage (~90% of total energy use). Regarding greenhouse gases, liquefaction was the key issue. When transitioning from HFO to LNG, the systems were mainly influenced by a reduction in cargo capacity due to bunkering requirements and methane slip, which depends on the fuel supply chain (onshore has 64% more slip than offshore) and the engine type (4-stroke engines have 20% more slip than 2-stroke engines). The combination of alternative fuel supply chains and specific operational profiles allowed for a complete system assessment. The results demonstrated that multiple opposing drivers affect the environmental performance of maritime transport, a useful insight towards establishing emission abatement strategies.
