Agricultural Waste Drives us Closer to Greener Transport

Published

Composite materials made from agricultural waste could be used to produce sustainable, lightweight and low-cost applications in the automotive and marine industries.

A team of researchers, led by the University of Portsmouth, have developed a bio-composite material using date palm fibre biomass (biomass is a term that includes waste material from plants, food waste and sewage) that can be used in non-structural parts, such as car bumpers and door linings. The team also involved researchers from the University of Cambridge, INRA (Institut national de la recherche agronomique, a French public research institute dedicated to agricultural science) and University of Britanny, South.

The date palm fibre polycaprolactone (PCL) bio-composite is completely biodegradable, renewable, sustainable and recyclable, unlike synthetic composites reinforced by glass and carbon fibres.

In a study, published in the journal Industrial Crops and Products, the researchers tested the mechanical properties of the bio-composite. They found that the date palm fibre PCL had increased tensile strength and achieved better low-velocity impact resistance than traditional man-made composites.

Dr Hom Dhakal, who leads the Advanced Materials and Manufacturing (AMM) Research Group at the University of Portsmouth and co-author of the study, said: “Investigating the suitability of date palm fibres waste biomass as reinforcement in lightweight composite materials provides a tremendous opportunity of utilising this material to develop low-cost, sustainable and lightweight biocomposites.

“The impact of this work would be extremely significant because these lightweight alternatives could help reduce the weight of vehicles, contributing to less fuel consumption and fewer C02 emissions. The sustainable materials can be produced using less energy than glass and carbon fibres and are biodegradable, therefore easier to recycle.”

The study is one of the first to provide a comprehensive assessment of the improved mechanical properties of date palm fibre PCL bio-composites.

Date palm fibres are one of the most available natural fibres in North Africa and the Middle East. Date palm trees produce a large quantity of agriculture waste, which is burned or land-filled, causing serious environmental pollution as well as the destruction of important soil micro-organisms. The part of the date palm tree which is often used as fibres is the sheath. The sheath is the part of the tree which surrounds the trunk of the plant. It is often torn lose when pruning the leaves.

“It’s a long journey,” says Dr Dhakal, “and we have to have patience and perseverance to make an impact. The challenge is getting consistent, reliable properties. It takes a long time to convince people to use a new class of materials, such as natural fibre reinforced composites for non-structural and structural applications.

“Meeting these challenges requires further research and innovation between academic institutions and industry.”

Dr Dhakal and his team have been working closely with industry to test the strength and viability of parts made from sustainable materials, such as date palm, flax, hemp and jute fibres. The AMM Research Group has been working in collaboration with researchers from institutions from around the world.

In the last 18 months, the group has published many high impact factor papers in journals including the Composites Science and TechnologyComposites Part A and Composites Part B.

A recent collaborative study, published in the journal of Composite Part A: Applied Science and Manufacturing explored the potential of waste leaf sheath date palm fibres for composite reinforcement.

Dangote monopoly Political Economy of Failure

By Adedapo Adesanya

Dangote Petroleum Refinery & Petrochemicals has advanced talks with the Société Nationale des Pétroles du Congo (SNPC) on a strategic partnership to supply refined petroleum products to the Republic of the Congo, in a move aimed at expanding its regional footprint.

The talks followed a visit by an SNPC delegation to the Dangote Refinery in Lekki, Lagos, led by the Congo state oil company’s Managing Director, Mr Maixent Raoul Ominga.

During the visit, Mr Ominga described the refinery as one of Africa’s most significant industrial achievements and said the Congolese national oil company was interested in building a long-term partnership with Dangote.

According to Mr Ominga, discussions centred on opportunities for collaboration in crude refining, petroleum products supply, energy security, industrial development and technical knowledge exchange. He noted that although the Republic of the Congo has its own refining capacity, working with Dangote would strengthen fuel supply, improve value creation and deepen cooperation between the two organisations.

The SNPC chief also praised the Dangote Group for demonstrating that African companies can finance, build and operate world-class industrial infrastructure.

He further commended the group’s investments in Congo’s cement industry, saying they have expanded local production capacity and improved the availability of construction materials.

On his part, the chief executive of Dangote Industries Limited, Mr Aliko Dangote, reaffirmed the company’s commitment to Africa’s industrialisation agenda through regional partnerships and value addition.

“We are for Africa, not just Nigeria. Tell us what you need, and we will see how we can work together,” Mr Dangote said.

He added that the Dangote Refinery has established a new benchmark for fuel quality on the continent by producing petroleum products that meet international specifications, while helping African countries reduce dependence on imported refined fuels from outside the continent.

Group Vice President, Oil and Gas, Dangote Industries Limited, Mr Devakumar Edwin, outlined the company’s long-term expansion strategy, revealing plans to increase its total refining capacity to 2.1 million barrels per day. The expansion will comprise 1.4 million barrels per day in Nigeria and a proposed 700,000-barrel-per-day refinery in Kenya to serve East African markets.

Mr Edwin also disclosed that the Dangote Group plans to invest an additional $46 billion between 2026 and 2028 across its refining, cement and fertiliser businesses as part of its broader strategy to accelerate industrialisation across Africa.

The duo of Oando Plc and Transcorp Plc have been evicted from the NGX 30 Index by the Nigerian Exchange (NGX) Limited in the 2026 half-year review of market indices.

In a statement from Customs Street on Wednesday, it was disclosed that Unilever Nigeria Plc and NASCON Plc are the new members of the elite index.

Designed using the market capitalisation methodology, NGX indices are reviewed semi-annually on the first business day of January and July to ensure they remain aligned with evolving market dynamics and international best practices.

The exchange reserves the right to make further adjustments where necessary in the event of mergers, acquisitions, trading suspensions, resumptions or other corporate actions prior to the effective date of an index review.

Business Post reports that the consumer goods, banking, insurance, industrial goods, energy, pension, and pension broad indices did not witness any entry or exit.

However, the Lotus Islamic index saw the inclusion of Nestle Nigeria and Cadbury Nigeria and the exit of NASCON. Stanbic IBTC Holdings was added to the Afrinvest Bank Value index, with Access Holdings leaving the Afrinvest Div Yield index after the inclusion of Seplat Energy, Fidelity Bank, Stanbic IBTC Holdings, Custodian Investment, and NAHCO.

IMF Says Nigeria Omitted Public Spending Worth 2% of GDP From Budgets

Rethink Relationship With IMF Nigeria

By Adedapo Adesanya

The International Monetary Fund (IMF) has revealed that Nigeria had about 2 per cent of GDP worth of public spending not recorded in recent official budgets, creating a gap between its reported deficit and actual financing needs.

IMF resident representative in Nigeria, Mr Christian Ebeke, said on Wednesday, during a session with business executives in Lagos, the country’s commercial capital.

The discrepancy means the country’s fiscal deficit appears smaller than the level of borrowing, because some capital spending was not included in budget documents or implementation reports.

Mr Ebeke said these unreported expenditures are linked, in part, to large government projects carried out off-budget, distorting assessments of Nigeria’s fiscal stance and public investment levels.

“So far, we think that there are about 2 per cent of GDP of expenditure that were not reported that should be reported and should be recorded, so that this statistical discrepancy will disappear,” said Mr Ebeke.

The lack of full reporting can also complicate coordination between fiscal and monetary policy, as policymakers may not have a clear picture of the true deficit, he added.

Mr Ebeke also clarified that the Nigerian government has begun addressing the issue by repealing and revising recent budget laws to incorporate previously unrecorded spending, though updated implementation reports are still needed.

He added that improving transparency is critical, noting that off-budget spending raises concerns about procurement processes and oversight.

In its latest Article IV review, the IMF praised Nigeria’s sweeping reforms, saying they had strengthened economic stability and investor confidence, but warned that the benefits had yet to reach millions of citizens and could be undermined by global shocks, including the Middle East conflict.

According to the Bretton Woods institution, the implementation of Nigeria’s new tax laws should gradually increase revenue collection, while the use of digital tools to track, verify and collect revenues could reduce leakages and corruption vulnerabilities.

The IMF said higher revenues would create fiscal space for development projects and social spending, but warned that the timing of any additional taxes should take into account the country’s worsening social conditions.
