In the EU, annual waste generation is estimated to be five tonnes per capita. The EU 2035 target is to reduce waste generation, improve waste management and limit the share of municipal waste landfilled to 10%. This presentation will reveal the results of two projects, funded in 2019 by the Lombardy Region, to provide solutions to this challenge, drawing synergies and connections from the perspectives of the circular economy, energy, green chemistry, and the ecosystem.
- Design processes, materials and technologies to improve the effectiveness of organic waste
management, creating a set of biorefineries to produce biofuels, biomethane, hydrogen,
fertilizers and biomaterials
- The energy transition in Lombardy towards renewable energy and sustainable
mobility; promoting the application of the circular economy to the waste cycle, with the
production of energy, chemicals, and renewable fertilizers (end-of-waste)
- Stimulating the process of decarbonization and the reduction of environmental impacts
resulting from the circularity of the process and, therefore, the reduction of emissions

This session will address questions around the effectiveness of a ‘smart bin’ technology solution whilst showcasing a real-life case study from a UK local authority.
- What is the Internet of Things [IoT], and how is it used in ‘smart bins’?
- How did the technology solve particular challenges for this local authority, such as overflowing bins, bin fires and inefficient collection routes?
- What were the quantitative financial gains from this installation?
- What additional social and environmental benefits were achieved?
- How can other waste management teams apply the lessons learned from this case study?

The fact that any given population has, with respect to others, a different waste generation profile in terms of quantity and typology, is a consequence of various factors. Between them, social and economic factors play a significant role in waste generation. Using the region of Gipuzkoa in the Basque Country, Spain as an example, this presentation will demonstrate how, and at what level, socioeconomic indicators affect the behaviour of the population in terms of urban waste generation.
- What are the challenges of quantifying food waste from urban waste generation data?
- What are the urban waste generation patterns in Gipuzkoa?
- How can we correlate socioeconomic factors with urban waste generation data?
- Which socioeconomic factors influence total urban waste generation rates the most?
- Which socioeconomic factors influence urban biowaste collection rates the most?
- How can we estimate the influence of socioeconomic factors on food waste generation
from urban waste generation data?

Waste-to-fuel technology (W2F) has been developed at the Eni Research Center for Renewable Energy and Environment in Novara. It is an alternative to traditional recovery technologies, converting the organic fraction of waste into bio-oil. A key characteristic of this patented solution is the use of hydrothermal liquefaction (HTL), without the use of a catalyser, thereby reducing CAPEX and OPEX. The main product obtained thorough this W2F technology is a bio-oil that can be used for the formulation of fuels for marine use, with a low sulphur content in a mixture with other raw materials; or, alternatively, as a raw material used in addition to, or in partial replacement of, crude oil in the refinery processes.
- Is OFMSW management critical in Italy?
- What are the mainstream approaches to OFMSW valorization?
- Are there specific advantages to waste-to-fuel technology?
- What development strategy is Eni pursuing?

The rapid increase in waste generation exerts considerable pressure on conventional, centralized waste management systems. The waste-to-energy sector is looking continuously to develop and implement new solutions aimed at reducing CO2 emissions, improving efficiency and lowering the environmental footprint. It has become necessary to evolve towards more decentralized systems, based on smaller EfW plants, integrated to the urban environment to minimize waste logistics.
- Key strategies and technologies that organizations can adopt to generate EfW effectively
- Supporting the move to a low-carbon and circular economy; the role of decentralized WTE
- What role does EfW have to play in evolving circular economy systems?
- The advantages of decentralized WTE, and the technical and legal implications for investors
- What opportunities lie ahead for investors?
- Working principles and features of the organic rankine cycle
- WTE solutions based on ORC technology
- The benefits of thermal oil boilers in comparison to steam alternatives

With an ever-expanding global population, and a consequent rising production of waste, together with the prospect of increasingly strict targets and regulations on the management of that waste, the challenge facing the sector is significant. This session will outline the main challenges and paint a positive, but realistic picture of how the sector can meet them.

Biomass and waste-to-energy plants are operated with solid fuels and therefore imply boiler fouling. Regular cleaning of all boiler heat exchanger surfaces is necessary to maintain a high efficiency and achieve long operating periods. This presentation will explain the successful implementation of shock pulse generators at the waste-to-energy plant ‘KVA Bern Forsthaus’, in Bern, in order to achieve a major increase in plant performance. It will show that significant improvements (capacity increase by 110%-120%) are possible with only a small investment.
- Maximal waste throughput of WtE plants is limited by plant size and operating fluctuations
- Boiler cleaning by shock pulse generators enables constant operating conditions, with minimal
- Additional positive effects: homogeneous ash discharge, a longer operating period, and a longer lifetime of superheaters
