A booming solar and storage market takes centre stage at All-Energy 2017

A booming solar and storage market takes centre stage at All-Energy 2017

This is no surprise really, considering this year’s record solar PV installation rates and a growing interest in battery storage due to falling prices, as well as the recent advancement in smart technology and software platforms, and the rise of the Internet of Things. Commercial solar alone has accounted for 50% of new capacity installed in Australia this year.

This is a reflection of the current state of play in the country, where businesses and households are demanding greater access to technologies that can deliver cheaper power bills and an even more reliable energy supply than what they are getting now. Read more

Waste Opportunist: liability for climate change in the waste management sector

Waste Opportunist: liability for climate change in the waste management sector

Yet, according to a report from the Australian Council of Superannuation Investors (ACSI), the level of climate-related disclosures by ASX200 companies lags behind the rest of their sustainability reporting.  ACSI found that 70 ASX200 companies did not measure greenhouse gas emissions, have a policy statement on climate-related risk, or a related target in 2016. More specifically, 116 of the ASX200 companies reported greenhouse emissions, 88 companies published a policy recognising the impacts of climate change as a business risk, but only 49 companies disclosed a climate or energy-efficiency related target.   Read more

Plastic Pollution - another cost on business

Plastic Pollution – another cost on business

When the United Nations Environment Program describes it as “alarming” and the G20 group of nations recognises “the urgent need for action to prevent and reduce marine litter in order to preserve human health and marine and coastal ecosystems, and mitigate marine litter’s economic costs and impacts”, then some pretty tough action is going to be on the agenda.

MWRRG shares flexible plastic kerbside collection learnings

MWRRG shares flexible plastic kerbside collection learnings

The ‘Introduction of flexible plastics packaging into kerbside recycling services’ project was aimed at recovering flexible plastic packaging through existing kerbside collections from four partner councils: Cardinia, Hobsons Bay and Nillumbik, launched in November 2016, and Boroondara launched in February 2017 (after council elections).

The area’s 170,000 households were sent information packs which among other explanatory information included 10 sample plastic bags which could be used by residents to start bagging their flexible packaging in their kerbside recycling bin. Printed text on the bags also listed what could and couldn’t be included. These council-provided plastic bags are not necessary to enabling flexible plastic collection, but rather were part of the first steps in communicating the initiative and encouraging household behaviour change

The ‘bag in bag’ technique stemmed from a 20-week trial run by the MWRRG with the City of Darebin and Sustainable Research Use in 2012, where it was found to be an effective method for the project’s establishment phase. MWRRG program coordinator, Nina Thomas, told Inside Waste the learnings from this initial trial (funded by round one of the Metro Fund) lay the foundations for this most recent project.

The 2016 project was also facilitated by the fact that the four councils all had existing recycling contracts with SKM Recycling. Flexible plastics collected at the kerbside are transported to SKM Recycling’s materials recovery facility where the material is sorted, compacted and baled for recycling either locally or overseas. The sorting process is currently conducted manually however, the company has committed $280,000 towards installing automated optical sorting equipment (supported by a further $10,000 from the Australian Packaging Covenant) at their new materials recover facility in Laverton which is currently under construction.

When asked about the long-term viability of flexible plastics collection – in the context of limited end market demand in Australia where it is still cheaper to import virgin plastic – Thomas acknowledged the issues, describing the situation as a “chicken and egg scenario”.

“There is a lot of interest [in this project] which is great, but you don’t want to jump in too quickly without having those end markets established and everyone on board. We need to take a step back before any sort of further project expansion,” she said.

“We can’t boost that local plastic reprocessing capacity until we have those end markets established, but then it’s difficult to establish those end markets without having the capacity. So this is where we need to consult with state and local government, industry, reprocessors and collection groups. We need to have those discussions and conduct research before we look at boosting the capacity and also before we look at what markets are available for those recovered plastics.”

The results of the project can be gauged by its fairly successful household participation rates and very low contamination rates. While kerbside recycling bin audits suggested 28% of households were engaging in the project, household survey responses indicated 60% of homes were using the service.

“We are assuming that this difference is because not everyone that’s participating in the program is putting a full bag of flexible plastics in their recycling bin every fortnight, so some of those audits wouldn’t have captured everyone participating in the program. Some people might have those bags of flexible plastics still in their home and still be filling them up before they put them in the recycling bin,” Thomas said.

“We had really low levels of contamination of 1% or less which also indicates the success of the information that went out. It just goes to show how residents really understood the education material. Some of the contamination items were things like foil wrappers of a chip bag which can be recycled through other flexible plastics recycling programs, but not this program,” she added.

The information material did present one of the program’s biggest challenges as each council had to have the material approved through their own internal communications teams.

“We didn’t expect to at the start of the project but our organisation ended up stepping in and playing a key role in the communications side of things to make sure that everyone was across all the communications materials that were going out,” Thomas said

Significantly, the project’s communications generated a lot of positive community feedback, including unprecedented social media activity and direct positive feedback to councils.

Bag audits show the material recycled is a broad mix of packaging: product packaging (40%), HDPE carry bags (25%), fresh produce bags (10%), trays and punnets (10%), other film such as stretch wrap and bubble wrap (10%), and LDPE carry bags (5%). Based on the conservative average of a 28% recycling rate and a yield per household of 6.5 kg per year, the project’s final reports estimates a yield of 371 tonnes in its first year, growing to a total of 1696 tonnes over the first three years.

Thomas will be joined by Sam Di Giovanni, coordinator waste management, City of Boroondara, to deliver the ‘Flexible Plastics Recycling’ talk on Wednesday, October 10 from 11am to 12pm at Waste Expo Australia, held at the Melbourne Convention and Exhibition Centre. Attendees can expect to hear about what was achieved, barriers and opportunities, risks and how they were mitigated, lessons learned, and next steps for increasing recovery of flexible plastics.

Paradigm shift makes waste managers out of water utility

Paradigm shift makes waste managers out of water utility

The facility was strategically constructed next to their Aurora sewage treatment and recycled water treatment plants, as well as local food manufacturers and a wholesale market. It is designed to divert 33,000 tonnes of waste per year from landfill as well as power both Aurora treatments plants. Any surplus energy will be contributed to the grid.

The project emerged at the tail-end of the millennium drought in 2011 as recycled water was becoming a part of Yarra Valley Water’s services, presenting a significant increase in energy costs. Commenting on the business case, manager waste to energy services Damien Basset said electricity generation was critical. This involved taking assets off the grid as feeding directly into the grid did not stack up economically. Read more

Tracking NSW's infrastructure needs

Tracking NSW’s infrastructure needs

Between 2002- 03 and 2010-11, the volume of waste that was recycled rose from 5.3 million tonnes to 10.8 million tonnes. Significant investment in new recycling infrastructure has played a big part in this jump and over the years, independent infrastructure needs analyses commissioned by the NSW EPA has helped inform the development of Waste Less Recycle More (WLRM) I and the approval of the second initiative.

In July, NSW EPA manager waste and recycling infrastructure, Robbie Beale, presented the findings of the regulator’s latest waste and resource recovery infrastructure needs analysis conducted by KMH at the Waste Management Association of Australia’s NSW Branch mid-year industry update seminar.
