ISB Global What is Pay As You Throw

What is Pay as You Throw?

Pay as you Throw, Pay by Weight or PAYT is a usage-based pricing model for the disposal of municipal solid waste. A range of different models exist according to region and country. Municipal solid waste is measured by weight and size, unit counts, bags, tags, containers and in some cases different technology solutions. The system identifies and confirms what address the container is associated and how much waste is being thrown away. In certain circumstances PAYT can also be applied recyclable materials too.

There are numerous ways that PAYT can be administered. Users can pay for the waste they throw away by bag or tag or specific container. A local authority can decide on number of bags or containers of waste and collection to be paid for by taxes. Additional bags and containers can be paid for should the limit be exceeded by the household. Households can rent containers for a variety of waste materials and the municipality charges according to that container filled.

The most widely used methods of Pay as You Throw is a standard charge rate for resources discarded or a taxation method. However, there is no real incentives to reduce the materials thrown away.  If the polluter pays by weight of materials not recycled then it is more of an incentive to recycle.

Some of the costs of waste management could be removed from property tax bills. This could provide more independence in the management of domestic waste management. Intelligent systems could provide more utilities focused models charged by unit of consumption.

Pay as You Throw can be effective in increasing materials separation and recycling and helping the waste hierarchy by minimisation of waste and the reduction in the consumption of materials. The environmental effects can be significant throughout the supply loop. Reduction on transport costs, increase in materials recovery and reduced GHG from landfills and incineration. Manufacturing and production also develop more efficient designs using recyclable materials with more sustainable life cycles.

Generally, the costs distributed in the Pay as You Throw model allocate charges fairly throughout the community to who produces or pollutes the most through the discarding rather than recycling of materials. Pay As You Throw supports community recycling schemes and sustainability initiatives. Lower income families are likely to produce less waste and therefore, pay lower waste collection fees.

Pay As You Throw can sometimes result in illegal dumping and fly-tipping, unlicensed and illegal disposal methods. In general however, increased litter and illegal dumping have not resulted in communities that have implemented Pay As You Throw, and the opposite occurs when combined with greater access to recycling and collective community based knowledge about sustainability.

ISB Global What is the History of Pay As You Throw

What is the History of Pay as You Throw?

From records, Austria seems to be the first to implement a type of Pay As You Throw Scheme by charging individuals for waste. But more modern forms of PAYT were not introduced until the 1980s when secure electronic systems could account for materials discarded. Dresden, Germany, was the first city to implement identification and a billing system in 2004. Spain started in 2003. And since 1991 European Waste Policy has required that part of the costs not covered by material reuse must be recovered from the polluter pays principle and subsequently a range of different PAYT schemes have been introduced across municipalities in Europe.

In the USA PAYT schemes have operated as early as 1932 in San Francisco. California, Michigan, New York and Washington started PAYT programs in the 1970s. By 2000, some 20%, or 6000 communities were being charged for waste management and within these states waste declined by 38% and recycling increased to 40%.

In Asia, after early introduction in the 1970s, 2008 saw 954 municipalities introduce a PAYT scheme. Taipei operates a bag scheme, encouraging the recycling of packaging, which is kept out of the bags and not charged for, this has reduced waste by 35% and there has been a significant increase in recycling in general from 1999. PAYT is also widespread in Korea, Vietnam, China, Thailand and Taiwan.

ISB Global What Countries are Best at Pay As You Throw

What Countries are Best at Pay As You Throw?

It is difficult to compare countries recycling rates as there are a range of materials recycled by different methods. EU member states are high as are Asian countries. Wales in the UK is known to be high, currently the third in the world.

A report published by Eunomia and The European Environment Bureau (EEB) in 2017 identified the top 25 countries for recycling. It included a number of recycling practices in order to make a comparison. Legislation, policy, collection and service infrastructure conditions had an impact in the top 10 countries, which were identified as having a number of common recycling elements in place, PAYT is one of these common themes.

The adjusted recycling rates of municipal household waste of countries that have a variable rate charging scheme including Pay as You Throw are South Korea (53.7%); Switzerland (49.7%); Italy (49.7%); Belgium (49.4%); Netherlands (46.3%); Slovenia (45.8%); Singapore (34%). Germany (%56.1%) and Austria (53.8%) set there PAYT at regional and municipal level so weren’t identified in the report. 8 in total have a variable charging rate.

ISB Global What Are The Challenges with Pay As You Throw

What are the Challenges with Pay as You Throw?

There is a general agreement that Pay as You Throw programs (PAYT) reduce the quantity of waste that households discard. There is a difference of opinion on the costs and benefits that PAYT can provide. Some critics believe that domestic waste collections should be provided as a municipal service and paid for with taxes. Critics believe that if PAYT is adopted local property taxes should decrease. Advocates point out that PAYT is an effective method in reducing waste, citing PAYT systems reward households that reduce waste, shifting the costs of collection and disposal to those who generate the waste.

There is also the thought that PAYT fees can cost lower income families a greater proportion of their income resulting in what can be referred to as a ‘regressive tax’.

Two reports completed in Maine, the first in 1996, found a significant reduction in waste and increase in recycling rates from Virginian households. However, the estimated costs savings did not cover the administrative cost of the program. Illegal waste dumping and fly tipping were also noted. In the latter report, authors Kinnaman and Fullerton (2000) highlighted that the demand for waste and recycling programs and the relationship between regional fees and waste unit pricing should be balanced. The authors also highlight that certain municipalities could be greater suited to unit pricing programs than other municipalities and therefore, average results may not be applicable to all municipalities.

Other methods used to reduce the waste fees alongside illegal disposal was discarding waste in public places, commercial container ‘opportunities’, burning of waste materials, transferal of waste to other sites and locations or disposing of waste at work. Although reported not a widespread problem, ‘waste shifting’ had been evident in some areas.

Pelican Communications Report March 2018 sampled a small number of UK households on PAYT. 54% said recycling is ‘very important’; 51% said they’re committed to recycling; 53% said they not always sure if something is recyclable; 37% said there is a lack of space in recycling bins; 86% said they had not heard of PAYT; 37% said they ‘maybe’ supportive of a PAYT scheme; 79% said a PAYT encourages recycling; 54% said that it will be more expensive; 42% said they would support a fixed fee scheme; 36% said they were very concerned about the increase in fly tipping; 30% were very concerned about lower income families ability to pay; 45% would prefer reward and encouragement to recycle more; Just 18% thought utility based schemes would be a better idea than PAYT.

ISB Global What are the Systems to Manage Pay As You Throw

What are the Systems Required to Manage Pay As You Throw PAYT?

In the context of Municipal Solid Waste Management, Pay as You Throw or Unit Based Charging, Differential, Variable Rate or Variable Fee Charge systems are economic instruments that apply to polluter pays principle at a municipal level by charging inhabitants according to the amount of waste they produce.

Technical implementation of the PAYT approach is based on the following three tracks: identification of the waste generator; measurement of the amount of waste sent to treatment; unit pricing of the unit by which the service is charged, container volume or weight.

The charge could be based on the weight of the waste generated and also the basic and variable service fee, reflecting to cost structure of waste disposal, which consists of fixed and variable costs. The inclusion of a fixed basic fee helps avoid illegal disposal methods, which can increase when applied to collected quantities.

ISB Global Pay As You Throw System Components

The PAYT approach means a substantial part of the fee is allocated according to the amount of waste collected. This motivates waste prevention and recovery. In accordance with the waste fee components, the PAYT approach can be implemented in different ways depending on the accounting method.

  • Per User Identifier – Volume Based & Weight Based
  • Per Bin Identifier (Individual / Collective Assigned Containers) – Volume Based (ID) Weight Based
  • Pre-Paid System – Pre-Paid Bag / Tag, Sticker or Token

The most common forms of PAYT are volume based schemes (the choice of container size), bag based schemes (number of bags set out for collection), weight based schemes (weight of the container collected) and frequency based schemes (the frequency with which a container is set out for collection). This can be combined with volume and weight-based schemes. Bags are usually filled so that weight and volume are relatively constant in relation to fee paid per bag.

Past studies have shown that pre-paid sack schemes achieve good performance. But volume-based systems using varying bin sizes achieve comparatively poor performance in waste and recycling. The highest recycling rates and lowest residual waste are achieved with weight-based systems when they are accompanied by well-developed infrastructure and supported waste aware citizens.

Implementation of Systems to Manage Pay As You Throw (PAYT)

Initiation of systems to manage PAYT require considerable effort to acquire data for billing, accounting and system optimisation. In container-based systems, all bins and containers need to be coded and collection trucks equipped with reading and weighing devices. Data is transferred to a central facility, in real time, where processing, accounting and the billing of end users occurs. There should be sufficient automated analytics in place to be able to interact with the data, providing robust information on both key aspects of operations and accounting to be able to refine and further optimise the process. This will be especially prevalent when experimenting with the best mix of unit-based charging for the specific territory and user group.

It may also be necessary to provide an identification chip that can be read by a transponder. A barcode can be used for identification and can also be used for ordering and delivery of containers. Multiple dwellings cause additional challenges and may in some circumstances require larger shared containers and require lock and key to prohibit unauthorised use. There are also additional difficulties with apportioning volume of waste materials to household in the case of multiple dwelling establishments such as flats and high-rise buildings.

Vehicles that are fitted or retrofitted with appropriate identification and weighing equipment. And require frequent calibration and maintenance to ensure all systems operate correctly.

Benefits arising from the PAYT system include the existence of well-developed infrastructure to separately collect and process the different types of material streams from homes as well as provision for alternative streams to be dealt with appropriately in recycling centres. It has been reported that socio-economic factors and environmental awareness are important for PAYT success.

ISB Global Pay As You Throw Integration

Integration versus Interface & Separate Software Applications

The challenge with the software landscape detailed in Diagram 2 is that there can be a large amount of applications, storage and interfaces to manage the complex process of planning, capturing, managing variance and matching data sources. This hinders the swift and accurate billing and accounting transactions that are required when the data matching process happens upstream. This should all occur without putting additional strain on what could also be a separate application in a customer service centre environment, to follow up if there are problems with collection, billing and invoicing processes.

Separate, interfaced applications have their own sources of master data, require linking and matching multiple additional data sources. They also require a sequence of process and data and often a separate interface to be built to match data model and transferal up and downstream. The more interfaces that are required, the more the landscape needs to be maintained, it can quickly become outdated, costly, inaccurate and rely on manual intervention.
