Widespread use of disposable single-use sanitary items, nappies and disposable wipes are causing harm to the land and marine environments. Many sanitary items can contain significant levels of plastic (e.g. up to 90% plastic in some menstrual items) and can form a large proportion of household waste (e.g. in 2022 nappies accounted for 10%). With the Single Use Plastics Directive and Waste Action Plan for a Circular Economy aiming to reduce single use plastics, and extend producer responsibility requirements, this research focuses on the use of more sustainable options for nappies, wipes and menstrual items. The research combined educational workshops and the provision of reusable alternatives through both the ‘Cloth Nappy Incentive Scheme’ and the ‘No Plastic. Period. Programme'. With a high level of public participation the research identifies four further research and four policy recommendations to enable increased national uptake of reusable nappies, baby wipes and menstrual items.

Globally, energy systems are undergoing two simultaneous and radical transformations that present a new set of challenges in sustainable waste management: the electrification of the transportation network and the decarbonisation of the electricity grid. This research examines challenges and models scenarios for the sustainable management of LongWEEE. Electrical devices with a longer than average lifetime are classed as LongWEEE with this study focusing on solar photovoltaic (PV) panels and electric vehicle batteries (EVBs). Modelled results for both sectors out to 2050 show a lot of uncertainty regarding the quantities of LongWEEE that will be generated in the future, but that in dealing with inevitable increases WEEE management systems need to to be prepared to cover a range of eventualities. Both “pay when placed” and “pay when collected” financing approaches to collection and treatment were examined in the study with the “pay when placed” identified as the most prudent approach.

The presence of contaminants in food waste bins requires further processing of the material, it incurs higher costs to remove the contaminants and results in lower value compost and digestate. This research indicates that the amount of plastic contamination in biowaste collections is increasing and that there is a need to significantly reduce the input of contaminants, particularly plastics, into the soil from the application of compost and digestate derived from food waste. Using 50 waste characterisation studies the research provides new information and insights on the trends in types of plastic contamination. With extensive stakeholder engagement and a comprehensive review of policy legislation, the research also provides policy actors and relevant stakeholders with information and recommendations on how to address issues associated with plastic contamination in compost.

Ireland’s ports and harbours are of strategic importance and are essential for its local, regional, and national economies. Ports are vital hubs that connect manufacturers, traders and consumers within global supply chains. Ports also play an important role in sustainable transport, as shipping is the most energy-efficient way to move freight and goods over longer distances. Nonetheless, ports can also be responsible for adverse environmental, health and social impacts such as air, water and noise pollution; traffic congestion; and damage to terrestrial and marine ecosystems. The (SHIP) project investigated methods to overcome challenges identified across the complex nature of ports and the diverse range of port activities and stakeholders to facilitate Ireland’s transition towards more sustainable port practices. It delivers a policy framework with recommendations on port governance, innovation, decarbonisation, port connectivity, efficiency and investment.

Ireland has registered a relatively poor score in terms of the Circular Material Use Rate (CMUR) – a key circular economy metric of the European Union. Ireland’s policy ambitions are to surpass the EU average in this metric by 2030. The aims of the CAIR (a Critical Analysis of Ireland’s circular material use Rate) project were to firstly identify factors driving Ireland’s relatively low CMUR performance and secondly to identify actions through which Ireland’s CMUR score could be improved. The research activities included an interrogation of how the CMUR metrics function, analysis of the data used, a comparison of the data and statistical profile of Ireland with three other Member States, and the development of proposals for improving Irelands CMUR score.

It is estimated that 550,000 cups per day are used in the Irish market alone, and that this could increase to an annual total of 300 million cups per year by 2025. Although there is a common perception among consumers that paper cups are recyclable, and thus a sustainable option, this is not necessarily true. These cups are lined with plastic, which is difficult to separate from the paper, and most paper cups are sent to residual waste streams for landfill or incineration. The concept of edible packaging has the potential to help address littering and waste management challenges from single-use disposable cups. EAT-Packaging undertook a life cycle assessment across a range of relevant cup types and engaged with national stakeholders to develop scenarios to identify where, when, and how edible cups (or alternative options) could reduce environmental impact for the functional unit of a cup containing a single drink.

Industrial activity is intrinsically linked to the accessibility and availability of water. The increasing global demand for industrial water poses a significant risk management challenge for organisations aiming to decouple the growth of production capacity from unsustainable consumption. This report presents a framework for industrial water users to adopt Industrial Water 4.0.

The EPA’s latest data (November 2022) show that municipal waste generation increased by over 440,000 tonnes in the last 5 years, and now amounts to 3.2 million tonnes. The VALOR study looked at how the resource value of the mechanically separated organic fraction of municipal solid waste (MS-OFMSW) can be maximised. The study also characterised the organic fractions of municipal solid waste (MSW).

Transport is by far the largest source of energy-related CO2 emissions in Ireland. This highlights the need for a rapid transition from a linear fossil fuel-based economy to a bio-based economy that treats waste as a commodity, reduces GHG emissions, sequesters carbon and produces biofuels, biofertilisers, and bioproducts. The aim of the Advanced Gaseous Biomethane project was to develop an integrated system that produces biomethane using biomass to fuel the transport sector cleanly and support Ireland in achieving key emissions targets.

The production of plastic packaging for food and other products has increased substantially over the past 50 years. The ReWrapped project investigated why Ireland’s production of plastic packaging waste appears to be higher than that of other EU Member States. The project also undertook a survey of producers to help understand what drives their use of different types of plastic and the extent to which sustainability considerations influence their decision-making.

There are pressing economic and environmental concerns regarding the imbalance between resource consumption and regeneration. This research successfully demonstrated a paradigm shift in how wastewater is treated by developing a pioneering cascading system for valorisation of dairy wastewater, based on circular economy principles. It successfully developed an integrated system coupling microbial-based technologies of anaerobic digestion and aerobic dynamic feeding with duckweed cultivation.

Ireland has met or exceeded collection and recovery targets for waste electrical and electronic equipment (WEEE) in recent years. However, as targets have risen, Ireland’s stakeholders must identify and address challenges presented by WEEE that does not arise in collection. This research identifies two pathways by which UEEE is exported for the purpose of reuse, namely through the shipment of roll-on roll-off vehicles and through the shipment of professional IT equipment, and it aims to quantify the amount of UEEE exported through each pathway.
