The state of waste 2015: recycling is only set to grow

Australia generates 48 megatonnes a year of waste, according to the latest National Waste Data Report 2014. In the period 1997-2012 our population rose by 22 per cent but waste generation increased by 145 per cent.

There are more of us and we generate more waste per person, each year.

On the positive side, recycling is growing at a faster rate and since 2005 we have actually seen (for the first time) a decline in tonnages of waste sent to landfill (in the most progressive states).

We now recycle about 52 per cent of all the waste we generate and landfill the rest.

Levies

Across Australia governments are increasing their landfill levies – the taxes paid by all companies and councils – for waste sent to landfill. These are intended to price the unintended externalities of landfill and to provide a price signal to promote recycling over landfilling.

The effect of the levies has been to drive waste costs for most companies from one per cent of operating costs towards 2-3 per cent. While these are small numbers they equate to a significant hit on EBITDA and profit.

Remote landfills are exempted from the levies in some states.

On the other hand Sydney landfill prices crossed the $300 a tonne threshold in 2012 and continue to set the trend for other states.

It is important for all waste generators to understand that the levy is avoidable. It is only paid on waste actually landfilled. In other words, if you don’t want to pay the levy, then recycle.

Infrastructure

The landfill price rises are driving resource recovery infrastructure investment and reform.

For most states the levies are now a significant revenue source. In NSW, the landfill levy raises more than $500 million a year.

To its credit, the NSW government has used these funds to establish a $465.7 million four year infrastructure and recycling grants program. These funds are granted to private companies and councils (up to $5 million and $10 million respectively) for new or improved recycling infrastructure.

Victoria, SA and WA all have similar schemes though at a lesser scale. Tasmania is exploring a $10 a tonne levy. Queensland had a levy for two years but it was dropped in 2012. The effect was a 20 per cent decline in recycling rates, the loss of jobs and the transportation of waste from NSW to Queensland.

The NSW levy, combined with the grant funding, is seeding a renaissance in the development of new recycling infrastructure and job creation. In fact, recycling is probably one of the only manufacturing sectors showing real growth and increased employment in NSW.

Jobs – largely recession proof

Recycling jobs are largely recession proof. Recycling rates do not generally swing as high or as low as the broader economy and much less than sectors such as mining, tourism and construction. Recycling jobs are mostly blue/green collar jobs. Recycling is a prime source of new jobs creation. For every 2.8 jobs in landfill we create 9.2 jobs in recycling. The sector employs over 30,000 people now and is worth over $11 billion per year.

Given the job creation potential of recycling, why does landfill continue to be the de facto method of waste disposal for 50 per cent of what we generate?

First and foremost – cost. Landfill is cheap. Many, especially local government owned landfills, have been inherited from past generations and don’t include the cost of replacement, rehabilitation and gas management in their pricing. State governments are coming to the realisation that this needs to be remedied and this will push up landfill pricing via reform and true cost pricing.

Commercial waste

Commercial waste remains a key challenge with recycling rates in this sector averaging just 40 per cent or lower. The reason – business owners are economically rational. They recycle materials that are economically viable (cardboard/paper and metals, which have inherent commodity value) and landfill the rest.

Business owners must weigh the additional costs of labour to sort materials for recycling against the costs of landfill. Cheaper landfill equals lower recycling rates and vice versa.

One important innovation will be the introduction of weight-based charging for commercial skip bins. These are the front lift three cubic metre bins with lids behind most pubs, offices, restaurants. At present most front lift bins are charged by volume not by weight. So a business can pay as much for a bin with one piece of polystyrene in it, as another with half a tonne of rubble.

New weighing systems now permit legal trade based on weight. Weight-based charging will provide a direct price signal to business managers and will be the biggest single reform in the commercial waste sector for decades.

The next big innovation will be “Commercial dirty MRFs” (materials recovery facilities) to recover recyclables from mixed business waste. The rise in landfill levies, combined with new government infrastructure grants, is now making large scale recovery plants commercially viable.

The commercial sector is now also funding extended producer responsibility schemes for the collection of televisions and computers, oil and tyres. New EPR schemes are in development for paint, batteries, smoke alarms and gas bottles to name a few.

Energy from Waste

EfW will transform waste management in Australia. Rising landfill costs, new state policies and financial grants, are accelerating the move to EfW as an alternative to landfill. Best practice EfW includes gasification, pyrolysis, plasma arc and incineration and variations on these technologies. Already we have proposals for three EfW plants in Perth, one is operating in SA and at least another two are proposed for Sydney.

NSW, Victoria and WA have given the green light to EfW via new policies. These generally have three preconditions: EfW must not cannibalise recycling; plants must meet high air emission standards; and they must be bona fide energy generators (not just waste disposal).

Construction waste

Another piece of the waste puzzle is the construction sector, which generates 40 per cent of Australia’s total waste. This sector has the highest recovery rates at approximately 60-80 per cent, because the waste materials are more homogenous (timber, metal, concrete), are heavy and therefore costly to landfill (and responsive to levies), and can be sold in large volumes back into robust construction markets. New star rating systems are also being introduced for building refurbishment and demolition.

Household waste

In the household sector, key reforms include the implementation of a third “green” bin for household garden and food waste and new 360 litre recycling bins for those households who need more volume (about 17 per cent of households fill their recycling bin to capacity each fortnight).

Almost 25 per cent of all recyclables are placed in the wrong bin by householders and this typically goes to landfill. Improving education will have some effect on this “loss”.

Many councils are also contracting AWT (Alternative Waste Technologies) to sort through the garbage bin – to recover recyclables and convert the organic component into low grade compost. These will continue to grow.

Some minor streams including mattresses, polystyrene and batteries can now also be recycled, as a result of support by government and the participation of charitable organisations.

Role of government

The role of government (particularly state government) is to clearly articulate where on the “recovery spectrum” they intend to sit (low cost landfill and lower recycling rates; and vice versa) and then to develop the appropriate policies, regulations and funding arrangements to make it happen.

Most businesses want to do the right thing but they are also economically rational. They will recycle to the extent limited by cost and return.

Most businesses and households support higher recycling rates and somewhat higher landfill levies, but only where a significant amount of the levy revenue is hypothecated to recycling infrastructure and systems.

As one local government councillor put it to me: “No one likes paying taxes but better they be progressive taxes than not. Better that we tax pollution and improve recycling, than tax payrolls and increase unemployment.”

With that sentiment in mind, rising landfill costs and improved recycling rates driven by new infrastructure, services and more recycling jobs, are with us for the long term.

    I know data can be very hard to find in this field, but can you tell us what is the overall volume and composition of Household Waste? How much do we generate (in total, or per household, or per person), how much is recycled, and what is the contents of what we send to landfill? Thanks very much.

    • Mike Richie says:

      Australians generate 23 million tons of waste to landfill per year, which is equivalent to 1 t per person per year.

      About a third of this is household waste, the remainder is commercial and demolition waste.

      The national waste policy is a good source of data.

      Two thirds of what a household generates is organic waste (food and garden material). Much of this is now being composted and across Australia that is certainly the trend amongst many councils.

  • Steve Ford says:

    A broadly interesting article but it disappointingly missed the point that the quality of the recycling outcome is important alongside the quantity. Dirty MRFs and energy from waste generally have low quality outcomes. Surely we can show greater innovation at the source to reduce waste and increase recycling.

  • David Hodge says:

    Mike that was a great article, well balanced and to the point.

    Creating jobs and keeping valuable resources here in Australia for upcycling is our goal by diverting contaminated plastic films from landfill and EfW.

    Regards Dave

    Waste to energy incineration whether gasification, Pyrolysis or plasma arc is not recycling and it is grossly misleading to claim that it is. Waste to energy incineration destroys these waste resources and leaves a toxic ash legacy still requiring secure landfill ie 1 tonne of ash for every 4 tonnes of waste. They also release dangerous pollutants to the atmosphere such as dioxin and nanoparticles. They are also the most expensive way to generate energy and emit more GHG’s than coal and gas per unit of energy. They should not be granted subsidies or tax breaks for clean technology or renewable energy…becuase they are neither and therefore take scarce funds away from real renewable energy sources like wind, wave and solar. Local governments need to be very wary of this false waste management and climate solution. It’s a con!
