The nuts and bolts of micro-manufacturing in the township - a Cape Town case study

Introduction

Informal manufacturing micro-enterprises are prominent in many developing countries, and are important through their contribution to practical skillsets and potentially maximizing income earning opportunities for participants. This occurs through value-adding practices, application of specialized labour and local supply-chain linkages. As such the sector is a worthy recipient of economic development and policy attention. However, several factors constrain the growth of these enterprises (and in some cases are the very reasons for their informality): these include institutional barriers (e.g. regulation, taxation), an inability to compete globally, inadequate technology and infrastructure and a lack of skills.

Little research has been conducted on informal-sector manufacturing in South Africa, which has resulted in knowledge gaps as to the sectors’ size and its contribution to employment and economy. Recently, Fourie & Kerr (2015) provided national numbers at the industry level, using data from StatsSA’s Survey of Employers and the Self-Employed (SESE). They report results, for 2013, showing that 7.4% of informal enterprises are in the manufacturing sector; this is estimated to be more than 110 000 informal manufacturing enterprises countrywide. These provide work, in manufacturing, for 6.6% of all people working in the informal sector, amounting to more than 160 000 jobs for owners and employees in 2013. (The Stats SA Quarterly Labour Force Survey identifies approximately 2.3 million persons as employed in the informal sector in 2013.)

These national numbers provide the backdrop for this article, which presents findings of a local-level case study (Petersen et al. 2016) on the nature of informal-sector metal manufacturing and the supply-chains involved in such operations.

Background and research method

Informal microenterprises typically comprise a heterogeneous mixture of cash-based and largely unregistered economic sub-sectors such as trade (liquor, groceries, street food), personal services (hair and beauty salons), construction, mining, and manufacturing activities (see Charman & Petersen, Econ3x3 2015). Informal manufacturing activities typically include cabinet and bed making, shop fitting, crafting, shoe manufacture, clothing and others.

Within this grouping, informal metalwork micro-enterprises (MMEs) play a potentially important role in the township economy with respect to serving local demand for certain products. We used a supply-chain approach to investigate business activities and value adding in informal metalwork MMEs in some Cape Town townships to assess their business sustainability and business environment.

During mid-2014 we conducted interviews with and observed 30 informal MMEs that we encountered in the Cape Town townships of Brown’s Farm, Samora Machel, Nyanga Junction and Delft South. In addition, we conducted interviews with persons active in the MME supply chain (formal and informal enterprises), related logistics enterprises and policy makers. We also interviewed 50 potential metalwork consumers as they browsed MME products.

Informal MMEs: creating value in the township economy

Though obviously not a representative sample, this analysis reveals important information on the extent to which informal MMEs are value creators in the township economy. Also, MME operators operate and interact with both formal and informal sector businesses in their operations, making rational choices to do so. However, the research identified structural and operational challenges where intervention from a local government could bolster these enterprises.

Of the thirty MMEs interviewed, the predominant business type are welders (20) who specialize in electrical (arc) welding of steel into a variety of popular products such as gates, burglar bars and shack or shed structures. The other enterprises are: eight constructors of prefabricated shacks (so-called hokkie or zozo shacks), one appliance repairer and one tinsmith.

Twenty-five (83 percent) of these are owned and operated by males. The female participants in the sample operate exclusively in the street sales of prefabricated zozo shacks manufactured by their husbands/partners. The metalwork sector has a high presence of foreign nationals: fifty percent of these enterprises (15) were operated by South Africans and an equal number by foreign nationals from Mozambique (7), Zimbabwe (5) and DRC (3).

All of the interviewed informal MMEs operate from either their homes (both formal housing and informal shacks) or pavement areas. Such places are a constraint on activities and profitability due to noise complaints, exposure to weather, criminality (especially on public pavements) and strained relations with neighbours. In some cases, public pavements are rented from adjacent private landowners who also sub-let electricity and water to the MMEs. Electricity costs vary according to usage, from R50 to R200 or more per week. The high cost of this way of accessing electricity, given the significant energy demands of the typical metalwork enterprise, is a common complaint from the MME operators. Such residential and open street operations also tend to fall foul of local government town-planning and land-use zoning regulations, thereby exposing them to harassment or fines from local government officials.

Equipment is an important factor in metalwork, also indicating a constraining element. The most common piece of equipment is arc welding machines, in addition to a range of hand tools appropriate to the tasks. Portability of equipment is important - all tools have to be transported to work regularly in a range of toolboxes and bags. Fourteen of the thirty respondents own a motor vehicle - primarily bakkies.

All informal metalworkers both manufacture on orders for clients and sell finished (‘off the shelf’) products to the public. Purchases of ordered welded items generally incur a 50% deposit, with final payment (usually in cash) on fulfilment of the order. The deposit covers the raw materials and the balance is meant to cover the cost of labour. Zozos, burglar bars, gates and other fittings are installed at the client’s premises. Some metalworkers and tinsmiths primarily sell readymade products to passing foot traffic.

In the survey sample the majority of enterprises make gross profits in the vicinity of R5 000 per month or more, from turnover of R8 500 to R13 500 per month. From their stated incomes, but also their ownership of specialized assets such as tools, their prior work experience and skills, most MMEs appear to operate beyond what one would regard as survivalist levels – they tend to be market-oriented or growth-oriented enterprises that add substantial value to the township economy.

Informal MME supply chains

The research identified a range of interesting aspects regarding the supply chains surrounding this sector – notably how it is connected to the formal sector. Figure 1 shows the flows of material and labour inputs to informal MMEs from the formal and informal sectors, how value is added to the various commodities along the supply chain, as well as the broader operating environment of these enterprises. It reflects how informal MMEs support a formal and informal metal-supply sector (ranging from informal reclaimers to scrap dealers); the supply of transport, electricity and water services as well as real estate; and formal-sector value-adding services such as galvanizing. The overall supply chain is an interwoven network of both formal and informal businesses and operations, which serves to enhance efficiencies for the informal-sector MME operator.
