A SPECIAL VISIT TO SWM – Dr. Amy Khor, Senior Minister of State for Sustainability and the Environment and Transport, together with MSE and NEA members

March 20, 2024

 We received a very special guest at SWM on March 20, 2024 – Dr. Amy Khor, Senior Minister of State for Sustainability and the Environment and Transport, and guests from National Environment Agency (NEA) and Ministry of Sustainability & the Environment (MSE).

We spent a delightful afternoon with her and the teams from NEA and MSE, discussing key concerns surrounding the effort for sustainability and what we are doing for the environment as a commercial organization. SWM, being in the heart of innovation and circular economy, a large portion of our commercial effort goes into sustainable innovation as we continue to work closely with our strategic partners (NEU, NTU, LiVEco and others) to address unintended environmental impacts, providing services that are good for the organization and the society in the long term. Dr. Khor, together with the teams, did a site tour to understand our lithium-ion battery recycling line and the peripheral support enabling the recycling and repurposing processes.

Being environmentally responsible is a choice – it means SWM bases our business decisions on values related to respect for the environment and humankind, leaving behind a viable world for generations to come; the feeling of making a difference. This applies to SWM’s business – this is what SWM is all about.

Repurposing of Fruit Peel Waste as a Green Reductant for Recycling of Spent Lithium-Ion Batteries

ABSTRACT: The development of environmentally benign hydrometallurgical processes to treat spent lithium-ion batteries (LIBs) is a critical aspect of the electronic-waste circular economy. Herein, as an alternative to the highly explosive H2O2, discarded orange peel powder (OP) is valorized as a green reductant for the leaching of industrially produced LIBs scraps in citric acid (H3Cit) lixiviant. The reductive potential of the cellulose- and antioxidant- rich OP was validated using the 3,5-dinitrosalicylic acid and 2,2′-azino-bis(3-ethylbenzothiazoline-6-sulfonic) acid assays. Leaching parameters such as OP concentration (200 mg), processing temperature (100 °C), H3Cit concentration (1.5 M), reaction duration (4 h), and slurry density (25 g/mL) were systematically optimized to achieve 80−99% leaching efficiencies of Ni, Mn, Co, and Li from the LIB “black mass”. Importantly, solid side- streams generated by the OP-enabled leaching displayed negligible cytotoxicity in three different human cell lines, suggesting that the process is environmentally safe. As a proof of concept, Co(OH)2 was selectively recovered from the green lixiviant and subsequently utilized to fabricate new batches of LiCoO2 (LCO) coin cell batteries. Galvanostatic charge−discharge test revealed that the regenerated batteries exhibited initial charge and discharge values of 120 and 103 mAh/g, respectively, which is comparable to the performance of commercial LCO batteries. The use of fruit peel waste to recover valuable metals from spent LIBs is an effective, ecofriendly, and sustainable strategy to minimize the environmental footprint of both waste types.

JOINT NEWS RELEASE

Singapore, 28 March 2023

NTU Singapore and Se-cure Waste Management build pilot recycling plant to tackle lithium-ion battery waste with biomass waste

Following a successful proof-of-concept to recycle spent lithium-ion batteries using reagent extracted from fruit peel waste, Nanyang Technological University, Singapore (NTU Singapore) is partnering Se-cure Waste Management Pte Ltd (SWM), a Singapore battery recycling and processing company, to scale up the technology in a pilot plant.

The pilot battery recycling plant has the capacity to process up to 2,000 litres of spent shredded battery mixed with fruit peel derived solvents for extraction of electrode materials such as cobalt, lithium, nickel, and manganese.

The scientists from the NTU Singapore-CEA Alliance for Research in Circular Economy (SCARCE), who developed the technology of using fruit peel waste to tackle battery waste, is also looking at using other types of biomass waste.

A key feature of the pilot plant is its modular design, which allows it to be easily configured for optimal reaction conditions to extract different types of metal.

Currently, less than 5 per cent of spent lithium-ion batteries are recycled globally and the volume of these spent batteries is projected to reach 11 million tonnes by 2030. Such technology could meet the urgent need for a recycling solution that is environmentally benign and can be easily scaled up, said the scientists from SCARCE.

Located at Neythal Road off Pioneer Road North, the pilot plant has been operational since the last quarter of 2022. Over the course of this year, the NTU and SWM team will work to optimise processes that maximise the extraction yield of valuable metals from battery waste for reuse at pre-commercial scale.

They will also evaluate the plant’s technical performance and economic viability with the goal of commercialising the technology.

Associate Professor Dalton Tay from the NTU School of Materials Science and Engineering and Cluster Director of the Energy Research Institute @ NTU (ERIAN) said: “With the proliferation of mobility devices and portable electronics, the model of extracting raw materials from the earth, using them, then discarding them is clearly unsustainable. Instead of relying on conventional mining of resources, we need to look at recovering and reusing the precious metals from our electronic waste. This integrated lithium-ion battery recycling pilot plant serves as an important engineering platform that takes us one step closer. Thanks to the support of NTUitive, NTU’s innovation and enterprise arm, we are able to work with SWM to take our technology from lab to industry, bridging the gap in the innovation continuum and paving the way towards its commercialisation.

“The use of biowastes such as fruit peel discards to close the loop on lithium-ion batteries is also a unique value proposition for potential carbon offsetting and creation of new distribution networks for green commodities. This homegrown effort enables us to make great strides towards a new and green circular economy in tackling bio- and electronic waste.”

Mr Vince Goh, Managing Director, Se-cure Waste Management, said: “Our collaboration with Assoc Prof Tay and the setting up of the pilot plant allow the seed of local innovation to grow and eventually flourish. This also provides SWM a closed-loop solution beyond processing batteries while enabling a greener and cleaner recycling process for resource sustainability. SWM and NTU will evaluate the commercial feasibility of NTU’s technology at a meaningful scale. In combination with our upstream core expertise in robotics-enabled electronic vehicle battery discharging and dismantling, as well as battery processing, SWM offers a systematic management of e-waste for the entire cradle-to-cradle.”

Professor Madhavi Srinivasan, Executive Director, NTU Sustainability Office, and SCARCE Co-Director, said: “This collaboration between NTU and SWM is part of NTU’s commitment to build a sustainable tomorrow, and fosters outcomes that address industry and societal needs outlined in NTU2025, the University’s five-year strategic plan. It is also in line with Singapore’s Zero Waste Masterplan, which charts the strategies towards a sustainable, resource-efficient, and climate-resilient nation.”

The fruit peel technology to recycle battery waste developed by SCARCE is supported by Singapore’s National Research Foundation and the National Environment Agency (NEA) under the Closing the Waste Loop Funding Initiative (Award No. USS-IF-2018-4).

Such efforts are also aligned with NEA’s Environmental Services Industry Transformation Map (ES ITM) 2025 in harnessing opportunities in environmental sustainability, and to pre-position companies like SWM for emerging opportunities in growth areas such as electronic vehicle batteries recycling.

Using biomass waste to replace strong chemicals

In 2020, an NTU team led by Associate Professor Dalton Tay and Professor Madhavi Srinivasan successfully extracted over 90 per cent (in weight) of the precious metals found in processed lithium-ion battery waste in the lab using orange peel waste and made new batteries with these recovered metals.

This method of using fruit peel waste in place of conventional strong chemicals and acids to extract precious metals from battery waste is called hydro-organic-metallurgy.

The scientists have since successfully replicated their success in the lab using other types of fruit peel waste – such as the peel of pineapples, pears, and lemons – before working with local e-waste recycling company Se-cure Waste Management (SWM) to scale up this technology. The scientists are now looking into the possibility of using other types of biomass waste.

In this new pilot plant, the process starts with SWM shredding and crushing spent lithium-ion batteries to form a crushed material, from which plastics and metals like copper, aluminium, and iron are separated. On average, the company processes 18 tonnes of spent lithium-ion batteries every day.

The final product, called black mass, contains the precious metals – cobalt, lithium, nickel, and manganese – to be extracted for reuse.

Black mass is poured into the pilot plant and dissolved in chemical concoctions derived from fruit peel wastes that has been oven-dried and ground into powder. These concoctions, which the scientists have filed a patent for, are designed to leach out precious metals over low heat.

Fruit peel is rich in sugars, naturally occurring antioxidants such as flavonoids and phenolic acids, and organic acids – all of which will enhance the dissolution and recovery of metals from the battery waste.

The precious metals are then precipitated into metal salts that can then be used to assemble new lithium-ion batteries.

Earlier, the NTU scientists demonstrated that lithium-ion batteries made from recovered metals showed similar charge capacity to commercial ones.
