Industry 4.0 and the Internet of Things (IoT) are set to play a significant role in revolutionizing waste management. Semi-driverless collection vehicles and sensors are already used in waste collection systems. With the applications of robotics and AI, future waste treatment plants will be highly optimized facilities where no human will be in direct contact with waste. Almost all recyclables will be recovered and valorized. As with automation in other sectors, it will change the role of labour and job losses can be expected, especially for routine manual occupations, transport workers and operators.
A just transition approach is particularly important to address social justice concerns surrounding waste management systems in current use across the region. At present, the informal sector plays a key role in municipal waste collection in many of its cities. The integration of waste pickers as partners in waste management schemes is considered key to building just, inclusive and liveable cities in the LAC region. However, as countries and cities seek to modernize their waste management and recycling processes, this group risks being marginalized. Respondents to the Chatham House survey highlighted the need for the inclusion of informal workers in the waste management sector as a priority for a just transition in the region. The extent to which such inclusion is successful will determine whether the informal sector stands to win or lose from the transition to a circular economy.
The term ‘waste picker’ was adopted at the First World Conference of Waste Pickers, held in Bogotá in 2008, and in 2013, the mayor of that city introduced a formal payment system for waste pickers in exchange for their services in collecting and transporting recyclable materials. Some countries, like Chile and Brazil, have made efforts to include informal waste pickers in new waste management systems. International development cooperation also supports the inclusion of informal sector workers. An example is the EcoVecindarios (Eco-communities) project (2009–18), led by the Bolivian branch of the Swiss Foundation for Technical Cooperation (Swisscontact). The project supported the inclusion of waste pickers into the solid waste management system of the city of Cochabamba, subsequently being extended to the cities of El Alto, La Paz, Santa Cruz and other municipalities.
In addition to an inclusive approach towards waste picker communities, other success factors for a just transition will include the remediation of existing open dumping sites, support for affected communities, and behaviour change campaigns. Proper segregation at source is also key to the success of many waste valorization programmes; many countries in the region have already implemented separate collection programmes for different types of waste for this precise reason.
The bioeconomy – circular principles to ensure sustainability
Although the bioeconomy is a rather new term and concept, many countries across the region have adopted bioeconomy principles in the last two decades in a range of sectors, with different degrees of socio-economic and environmental impact. The bioeconomy offers many opportunities for countries in LAC, especially in the food and agricultural sector, but it also creates challenges. Opportunities arise because of the region’s broad biodiversity, genetic resources, diverse productive landscapes, and capacity to produce food and biomass. This is a commonly held view among respondents to the Chatham House survey, almost half of whom indicated that the food and agricultural sector will be among those to benefit most from the circular economy transition in the region. The main difficulty is in developing a sustainable bioeconomy that ensures protection of ecosystems and finds new pathways for more inclusive and equitable rural development.
The EU’s definition of the bioeconomy is as follows:
So far, unlike in the EU, there is no consensus across LAC countries on a definition – or an agreed regional vision that could serve as a reference framework to guide the development of national policies and strategies. According to ECLAC, consensus on the bioeconomy in LAC could be built on the following ‘four pillars’:
- Promote sustainable development, taking Agenda 2030 as a frame of reference;
- Promote climate action, taking as a frame of reference the Paris Agreement and the proposals of the countries in their nationally determined contributions (NDCs);
- Promote social inclusion (e.g. family farming, youth and women, indigenous peoples) and the reduction of territorial development gaps within countries; and
- Promote innovation processes that contribute to the diversification of economies and generate new value chains, especially those that contribute to regional development, are in high-growth market segments, or offer opportunities to young people and women.
Several countries in the region are taking a proactive stance on developing national bioeconomy plans and strategies. In 2016, Argentina launched its bioeconomy strategy document, and in 2018 the Argentinian government co-signed a letter of intent with the Inter-American Institute for Cooperation on Agriculture, which paved the way for the country to become a regional bioeconomy knowledge hub. In Ecuador, the bioeconomy is included in the national development plan and the Ecuadorian government is currently developing a national bioeconomy policy. Colombia has launched several strategies related to the bioeconomy since 2002, when it launched its National Plan on Continental and Marine Bioprospecting; the issue constitutes a core theme of Uruguay’s 2050 development strategy and Costa Rica’s National Decarbonization Plan for green economic development.
Forests accounted for about 46 per cent of the region’s total land area in 2015 and the region is home to 57 per cent of the world’s primary forests, which are the most important forest resources in terms of biodiversity, conservation and climate.
Forest resources and biodiversity are crucial for the bioeconomy. Of the world’s 17 ‘mega diverse’ countries (as identified by the US non-governmental organization Conservation International in 1998), six are located in the LAC region: Brazil, Colombia, Ecuador, Mexico, Peru and Venezuela. Forests accounted for about 46 per cent of the region’s total land area in 2015 and the region is home to 57 per cent of the world’s primary forests, which are the most important forest resources in terms of biodiversity, conservation and climate. With its diversity and abundance of natural resources, the region has great potential to further develop its bioeconomy. Areas of focus in the past two decades include the valorization of biodiversity resources in medicine and pharmaceuticals, ecological intensification of agriculture, biotechnology applications in sectors such as mining, food and beverage production, bio-refineries and ecosystem services.
However, the bioeconomy is not sustainable by definition. In many bioeconomy strategies, biodiversity is seen as a resource, at the same time, however, there is an urgent need to halt and reverse biodiversity loss in the LAC region. Observers are concerned about large-scale bioenergy production competing with food production for space, with potentially serious consequences for food security and land degradation. Bio-based plastics represent another case in point. Bioplastics are not necessarily sustainable: there is little regulation of their manufacture, and there are multiple resource-intensive factors involved in production, including energy and water inputs. In addition, the current infrastructure does not create the necessary conditions for these bioplastics to break down. Promoting bioplastic production and consumption is therefore not a cost-effective strategy for climate change mitigation, if production is based on conventional feedstock, due to greenhouse gas emissions as a result of direct and indirect land-use change.
While the LAC region should be able to develop its bioeconomy, this should not jeopardize its contributions to the region’s food security and biodiversity protection targets. Introducing circular economy principles into the bioeconomy can support the balancing of competing objectives, especially in the context of the SDGs. Circularity principles need to be a key element in achieving such convergence, not only for environmental reasons, but also on economic grounds. The alignment of circular economy and bioeconomy principles can improve resource and eco-efficiency, lowering greenhouse gas footprints and furthering the valorization of waste and production side streams. Examples of valorization include the utilization of organic waste streams from the agriculture, forestry, fishery, aquaculture, food and feed sectors. Furthermore, biodegradable products (e.g. natural fibres) can be safely returned to the nutrient cycle.
