UPDATE ON CARMICHAEL COAL MINE IN THE GALILEE BASIN:
The Productivity Commission raised the possibility that Adani’s Northern Australia Infrastructure Facility (NAIF) loan bid may fail the loan criteria. However the Queensland Government has vetoed the loan to fulfil an election promise. http://www.abc.net.au/news/2018-01-05/adani-loan-bid-likely-to-fail-before-palaszczuk-intervention/9305040 Aurizon, the nation’s largest rail freight operator, has requested a NAIF loan to build a freight link, opening the region up to coal projects, and ultimately helping facilitate the Carmichael mine. It is unclear if the Queensland Government’s veto covers this bid. https://www.theguardian.com/business/2018/jan/18/queensland-accused-of-breaking-no-public-funds-for-adani-promise However, Aurizon has withdrawn its NAIF application as it is unlikely to secure enough customer contracts to go ahead in the near future. http://www.abc.net.au/news/2018-02-09/aurizon-pulls-pin-on-naif-loan-application-galilee-basin-rail/9414074
Jambeck et al calculated that 275 million metric tonnes of plastic waste was generated in 192 countries bordering the Atlantic, Pacific and Indian Oceans, and the Mediterranean and Black Seas in 2010, with 4.8 to 12.7 million metric tonnes entering the ocean.

Henderson Island in middle of South Pacific Gyre –
At least 690 species have encountered marine debris and at least 17% of those listed on the IUCN Red List as near threatened or above. Of the individual encounters 92% were related to encounters with plastic and at least 10% had ingested microplastics..Gall S.C and R.C.Thompson (2015) The impact of debris on marine life. Marine Pollution Bulletin 92, 170-179 Many of these environmental impacts of marine debris especially from microplastics and nanoplastics have been covered in previous reports.

Risk to coral health from plastic debris: Assessing the influence of plastic waste on disease risk in 124,000 reef-building corals from 159 reefs in the Asia-Pacific region, Lamb et al estimated the likelihood of disease increases from 4% to 89% when corals are in contact with plastic. Three key diseases associated with rapid coral mortality increased markedly. Skeletal eroding band disease which can be caused by plastic debris opening wounds in coral tissue to let in pathogens, increased from 1.2 ± 0.1% to 43.9 ± 5.1%. White syndromes which can be caused by a pathogen colonising polypropylene which is used to make bottle caps and toothbrushes, increased from 1.9 ± 0.2% to 19.0 ± 4.0%. Black band disease which can result from plastic debris blocking out light and creating low oxygen conditions that favour the growth of microorganisms, increased from 0.6 ± 0.1% to 14.7 ± 3.9%. Structurally complex corals, particularly branching and tabular species are eight times more likely to be affected by plastic. This could seriously affect the numerous marine species that shelter under or within these corals, and in turn the fisheries that depend on them. The number of plastic items observed on each reef varied markedly among countries, from maxima in Indonesia [25.6 items per 100 ± 12.2 m] to minima in Australia (0.4 items per 100 ± 0.3 m2) Plastic waste associated with disease on coral reefs Lamb J.B., Willis B.L., Fiorenza E.A., Couch C.S., Howard R., Rader D. N., True J.D. Kelly L.A., Ahmad A., Jompa J. and C. D.

Land-based sources of the debris in the marine environment: Nearly half of the estimated 8 million metric tons of plastic that flow into the world’s ocean every year originate in just five rapidly developing economies in Asia — Indonesia, Philippines, Vietnam, Thailand, and China. To prevent this, Ocean Conservancy is seeking to raise over $150 million to design and build waste management and recycling systems in Southeast Asia. https://cleantechnica.com/2017/10/13/ocean-conservancy-campaign-targets-5-worst-ocean-plastic-polluters/
Hardesty et al found that within Australia, approximately three-quarters of the rubbish along the coast to be plastic. Debris was more highly concentrated around major cities, suggesting local source point pollution. As the quantity of debris increases in the marine environment, so does the likelihood of impacts from debris to marine fauna resulting in entanglement and ingestion and indirectly through chemical affects. Hardesty, BD, C Wilcox, TJ Lawson, M Lansdell and T van der Velde (2014). Understanding the effects of marine debris on wildlife. Final report to Earthwatch Australia Hardesty et al found that the strongest effect on debris count at a site to be due to littering behaviour. Transport by water was second, with a discernible but smaller effect from wind transport. The two strongest predictors of debris at a site were economic wealth and social disadvantage in the population near the site. Hardesty, et al.

Effect of the mobility of marine debris: Plastic debris and microplastics are transported by ocean currents across borders. Northern Australia has some of the highest densities of ghost nets in the world, with up to 3 tons washing ashore per kilometre of shoreline annually The Gulf of Carpentaria which is an important breeding area for several species of turtle (flat- back, green, hawksbill, loggerhead, and olive), is subject to an influx of abandoned, lost, or otherwise discarded fishing gear from the extensive fisheries of South-east Asia. Wilcox et al estimated that the total number of turtles caught by the 8690 ghost nets sampled was between 4866 and 14,600, assuming nets drift for 1 year. The risk from entanglement was quantified by mapping the distribution of turtles and predicting the drift trajectories of ghost nets using an ocean circulation model, to estimate probable encounter rates Wilcox, C., Heathcote, G., Goldberg, J., Gunn, R., Peel, D. and Hardesty, B.

Conversion of plastics to oil: The United Nations estimates plastic accounts for four-fifths of the accumulated garbage in the world’s oceans. This debris could be kept out of waterways by recycling existing plastics. Plastics can be converted to fuel by the pyrolysis process (heating the plastic in an oxygen-free chamber to about 4000 C to break down long chain polymers into smaller molecules) As the plastics boil, gas is separated out. The fuel is then distilled and filtered. Because the entire process takes place inside a vacuum and the plastic is melted minimal to no resultant toxins are released into the air, as all the gases and or sludge are reused to fuel the machine. However, some types of plastics e.g. pure hydrocarbons, such as polyethylene (PE) and polypropylene (PP) are more suitable than others for using this technology. PE and PP plastics are used in bottle caps, appliance plastics, nursery planters and dirty plastics such as meat wrappings With polystyrene (PVC) the large amounts of chlorine produced is likely to corrode the reactor and pollute the environment. Burning Polyethylene_terephthalate (PETE) which is widely used to bottle water and carbonated soft drinks, releases oxygen into the oxygen deprived chamber thereby slowing the processing, and is better recycled because of the high value of the resin. Several commercial machines are available for converting plastics to fuel. For example, in Niagara Falls, NY, John Bordynuik’s ‘Plastic Eating Monster accepts unwashed, unsorted waste plastics, composites and commingled materials and returns about 1 gallon of fuel from 8.3 pounds of plastic. In the UK Cynar’s ‘End of Life Plastic to Diesel’ product converts mixed Waste Plastics into synthetic fuels that are cleaner, low in sulphur and in the case of the diesel, a higher cetane than generic diesel fuel. https://insteading.com/blog/plastic-to-fuel The Japanese company Blest.co Ltd. markets small-scale systems that can convert PP, PE and PVC plastics into fuel oil. While Blest see a market in developing countries, they have demonstrated their Be-h machine (560 (W) x 320 (D) x 500 (H) mm; 50 kg) in schools in USA, Australia, Canada and Brazil educating children about environment issues and how plastics can be made into oil. The machine is claimed to be easy to set up on site so that it could be used where the waste plastics are collected and treated. http://www.wired.co.uk/article/blest-machine .http://www.blest.co.jp/eng/ http://www.hoaxorfact.com/technology/man-invented-a-machine-to-convert-waste-plastic-into-oil-and-fuel-facts.html Is there potential for service organizations to partner with schools? Given the mobility of debris perhaps even overseas schools?
UN initiatives: The Global Partnership on Marine Litter (GPML) of international agencies, Governments, NGOs, academia, private sector, civil society and individuals aims to
• To reduce the impacts of marine litter worldwide on economies, ecosystem, animal welfare and human health.
• To enhance international cooperation and coordination through the promotion and implementation of the Honolulu Strategy – a global framework for the prevention and management of marine debris, as well as the Honolulu Commitment – a multi-stakeholder pledge.
• To promote knowledge management, information sharing and monitoring of progress on the implementation of the Honolulu Strategy.
• To promote resource efficiency and economic development through waste prevention e.g. 4Rs (reduce, re-use, recycle and re-design) and by recovering valuable material and/or energy from waste.
• To increase awareness on sources of marine litter, their fate and impacts.
• To assess emerging issues related to the fate and potential influence of marine litter, including (micro) plastics uptake in the food web and associated transfer of pollutants and impacts on the conservation and welfare of marine fauna. https://www.unenvironment.org/explore-topics/oceans-seas/what-we-do/addressing-land-based-pollution/global-partnership-marine Having identified marine debris as a major global challenge UN Environment launched the Clean Seas campaign in an endeavour to eliminate major sources of marine litter by 2022, focusing on single-use plastic and micro-plastics in cosmetics. Governments are urged to pass plastic reduction policies; industry is being targeted to minimize plastic packaging and redesign products; and consumers called on to change their habits. https://www.unenvironment.org/regions/north-america/regional-initiatives/tackling-marine-debris. The UK, the US and Canada have announced bans on microbeads in personal care and cosmetics products, and the CleanSeas campaign is encouraging more countries to follow suit. http://web.unep.org/stories/story/cleanseas-more-800-people-pledge-stop-using-cosmetics-containing-microbeads Nearly 40 countries accounting for more than half of the world’s coastline have joined the UN’s CleanSeas campaign against marine litter and ocean pollution, announcing measures including plastic bag bans, new marine reserves and drives to increase recycling. http://www.cleanseas.org/news. At the close of the UN Environment Assembly in Nairobi 4-6 December 2017, environment ministers issued a declaration committing to increasing research and development, targeting pollution through tailored actions, moving societies towards sustainable lifestyles based on a circular economy, promoting fiscal incentives to move markets and promote positive change, strengthening and enforcing laws on pollution. Among the-non binding resolutions and decisions were moves to address marine litter and microplastics (submitted by Norway and Australia and co-sponsored by Iraq and Monaco), prevent and reduce air pollution, cut out lead poisoning from paint and batteries, protect water-based ecosystems from pollution, deal with soil pollution, and manage pollution in areas hit by conflict and terrorism. https://www.unenvironment.org/news-and-stories/press-release/world-commits-pollution-free-planet-environment-summit. http://enb.iisd.org/unep/oecpr3-unea3/ According to Boomerang Alliance, Australia has yet to commit support to the Cleanseas https://www.insidewaste.com.au/site/opinion/1052830/global-commitment-plastic-pollution-planetary-crisis-australias-response
Australian Government Initiatives: A threat abatement plan (TAP) prepared in 2009 and focusing on the impact of entanglement and ingestion of marine debris on vertebrate marine life was reviewed in 2015.It was noted that understanding of the global nature of the marine debris problem, as well as the potential sub-lethal and other impacts of microplastic and associated chemical contamination, had increased over the life of that plan. A Senate Inquiry report highlighted the need for improved action on many issues relevant to the TAP.

6. Increase public understanding of the causes and impacts of harmful marine debris, including microplastic and hazardous chemical contaminants in order to generate behaviour change.
6.01 Raise the profile of marine debris impacts on listed threatened marine species.
Department of Environment and Energy (2017) Draft Threat Abatement Plan for the impacts of marine debris on vertebrate marine life Australia is undertaking many useful initiatives e.g. governments extending marine reserves; supermarkets phasing out plastic bags; businesses banning plastic drinking straws. However, with 25,760 km of coastline and in receipt of other countries plastic waste e.g. ghost fishing nets, surely Australia could be more proactive with domestic legislation and using the UN Environment platform to argue for countries to take responsibility of the marine waste originating in their country? A submission to the Federal Government has been prepared on this issue.
