BnM, formerly known as , (; English: "The Peat Board") is a semi-state company in Ireland.

The company was created by the Turf Development Act of 1946 to mechanize the harvesting of peat to boost the economy of Midlands communities and the energy security of the recently formed Irish Republic.

Over the years, BnM has expanded and diversified its portfolio of businesses to include biomass procurement and supply, power generation (peat-based and renewable), waste recovery, domestic fuel products, professional and consumer horticulture products, eco-tourism, and community amenities.

In 2015, the company announced that it will stop harvesting peat for power generation by 2030, but will continue to do so for their horticulture and fuels businesses. Some have criticised the state subsidies for the company and the extraction of turf as the most environmentally unfriendly form of fuel and hurting local biodiversity.

History

Bord na Móna was originally established in 1933 as the Turf Development Board, Limited. The reason for the formation of the Turf Development Board was "to develop and improve the Turf Industry..." and "...to operate and drain bogs...". Later, in 1946 the Turf Development Board changed its name to Bord na Móna under the Turf Development Act 1946. This move saw a change in status from that of a limited liability company to a statutory company as well as some significant changes in strategy and operations. In 2020, the BnM announced that it was phasing out peat harvesting in Ireland. No jobs would be lost, and existing peat workers would be reassigned to bog reclamation projects rather than laid off.

On 15 January 2021 it was announced that peat briquettes would no longer be available after 2024.

In September 2025, it was announced that Bord na Móna had changed its name to BnM During the 1980s and 1990s, another internal drive saw the conservation of more bogs, including Bellacorick Flush County Mayo, Mongan Bog, Clara Bog, and All Saints Bog in County Offaly. These bogs are now owned and managed by An Taisce, the National Parks and Wildlife Service, and other organisations.

In 2010, BnM launched its first Biodiversity Action Plan. This plan set out a number of objectives and actions to be carried out over a five-year period 2010–2015. It gave an overview of rehabilitation work, natural colonisation projects, and the biodiversity of the company's cutaway bogs. It also highlighted the biodiversity projects in progress and those completed.

Harvesting

Peat was traditionally manually harvested by operating cutaway bogs. This method (still privately used today) consists of sods being vertically cut from the side face of a peat deposit. Technology was derived to mechanically cut and remove layers of peat from blanket bogs. Today, equipment is used to remove tonnes of peat each day at suitable times of year (rainfall is a significant variable in peat harvesting). Almost all the peat now harvested is milled peat, scraped from the surface of the bog by tractor-towed pin millers. The milled peat is ridged into small piles which are then transferred by harvesters into large piles running parallel along the bog. Railways are laid alongside each pile, the pile loaded into trains and the railway lifted and moved to the next pile. This is the 'Peco' method of working. A few bogs use the 'Haku' method whereby the milled peat is loaded into tractor-towed caterpillar-tracked trailers and deposited in a single heap at the edge of the bog adjacent to a railway line. Each year, the network of drainage ditches is deepened by a few inches before the next harvest.

BnM has developed a number of products which were novel developments in their time. Peat briquettes largely replaced sods of raw peat as a domestic fuel. These briquettes consisted of shredded peat, compressed to form a slow-burning, easily stored and transported fuel. The first peat briquette factory built by the Board, the Derrinlough briquette factory in Offaly opened in 1959, was financed with a loan of £500,000 from Guinness in 1957. Derrinlough, the last remaining briquette factory, out of four in total, closed in June 2023. Another product developed was peat moss, a combination of peat and soil used in gardening, particularly for pot plants. The company also supplied peat to power stations of the Electricity Supply Board and its own power station, Edenderry Power.The ESB peat stations were all closed by 2021 and Edenderry Power transitioned to 100% biomass in December 2023, ending all peat use by the company.

Railways

BnM had one of the largest industrial railways in Europe, which carried up to 4 million tonnes annually over 550 miles of rail.

Permanent railways ran from a hundred peat bogs, each covering hundreds of acres, to power stations, briquette factories, moss peat factories and roadside tipplers. On most of the bogs, temporary tracks were laid along piles of peat. Before a pile was cleared, another temporary line was laid a few hundred feet farther along. More than 300 kilometres (approx 180 miles) of temporary track were laid each year and the Bord had specialist track fabrication workshops, tracklaying machines, and a fleet of dedicated locomotives and rolling stock on hand.

A few bogs were operated by the Haku process, where the peat is collected in one huge heap at the end or side of a bog, requiring only one railway line to serve it.

An extensive narrow gauge network was operated by the company in the midlands. Some smaller sections of railway were used in other bog locations, such as in County Donegal.

Part of the Blackwater bog system was also used for tourist trains – the Clonmacnoise and West Offaly Railway (colloquially the "Bog Train") for about twelve years. This service ceased permanently in October 2008 as it interfered with the heavy peat traffic heading for West Offaly Power Station. One line of the Blackwater system ran along a section of the former Ballinasloe branch canal. This includes a section where the railway runs through Kylemore Lock. The newest branch of this system runs north from existing bogs at Bloomhill to the new bogs of Kilgarvan and Bunnahinley – the latter in the outskirts of Athlone – and opened for traffic c. 2011.

All three of BnM's old steam locomotives are preserved, one by the Irish Steam Preservation Society at Stradbally, County Laois.

Each of the three power stations – West Offaly at Shannonbridge, County Offaly; Edenderry, County Offaly; and Lough Ree, Lanesborough, County Longford, was the hub of an extensive rail network carrying heavy traffic. As an example, twelve trains or rakes (locomotive and sixteen wagons) were in daily use sixteen hours a day at West Offaly in April 2009. Other, generally older locomotives, handled fuel trains, track trainloads of track, ash trains, and permanent way gangs. the Edenderry Power Station derived much of its fuel from woodchips and other types of biomass. Thus the amount of peat arriving by rail is diminishing.

The two briquette factories at Derrinlough, County Offaly, and Littleton, County Tipperary, each had rail connections to six or eight working bogs. Between four and six peat trains worked on each system, the trains almost always travelling in pairs.

BnM also operated several smaller bog railways delivering the peat to tipplers for transfer by road to factories and power stations. These could be found at Gilltown, Ummeras, Kilberry, Prosperous and Almhain North, in County Kildare, at Coolnamona in County Laois, Derryfadda in Galway, Coolnagun, Ballivor and Kinnegad in Westmeath, Monettia, Bellair and Killaun in Offaly, and Templetuohy on the Tipperary / Kilkenny border. The Coolnamona Works is largely closed but the railway system was upgraded in 2010/11 to serve a new tippler supplying peat by road to Littleton (Lanespark) Briquette Factory.

Locomotives and rolling stock, for many years bought in from outside companies, were later designed and built in-house. New locomotives were 0-4-0DH (diesel-hydraulic) or (no connecting rods). Most peat wagons were of the bogie type, with aluminium bodies to reduce weight, though there were still thirty or so old steel-bodied wagons in use as of 2009. Templetuohy, the Bord's last traditional sod peat operation, used four-wheeled open-slatted wagons which end tip into waiting lorries.

With the ending of peat harvesting, the BnM railway system will cease operations. As part of the rundown of services, two of the most modern locomotives were sold to the Isle of Man Railway in 2024.

Land reclamation

The company is responsible, under government action, for reclaiming spent bogland. These areas of land are usually cleared up, with trees or other suitable vegetation being introduced. Reclaimed bogland is then usually used as a wildlife preserve. With much of the bogs of Ireland depleted, peat-fired electricity stations all closed by 2020. The demolition had been postponed to at least 2027, but now is planned for 2026.
