Environmental Conservation

Energy Conservation and Prevention of Global Warming

One of our goals is to reduce total lifecycle CO2 emissions by 30% by the year 2020 as compared to the level of the year 2000. To reach this goal, the Ricoh Group is working to lessen the environmental impact throughout the life cycles of our products, focusing specifically on the phase that has the greatest impact — the daily usage of our products. Current Ricoh products require less energy and help our customers to practice eco-efficiency in their work.

Energy-saving MFP can recover from sleep mode in as little as 5.1 seconds*1

In June 2013, Ricoh launched the RICOH MP C6003/C5503/C4503/C3503/C3003 series, a family of fullcolor MFPs with a very short recovery time from energysaving (sleep) mode. Ricoh's new Quick Start Up (QSU) fusing system*2 and Color PxP-EQ, a low-temperature fixing toner, were the keys to this achievement. Sleep mode power consumption was also cut to less than 1W through the use of an application-specific integrated circuit (ASIC) that uses a low level of electricity.
The RICOH MP C3503/C3003 series consumes just 0.5 W in standby power, even when its network function is on, and also features a very quick recovery time of as little as 5.1 seconds — a vast improvement over the previous model*3 (7.8 seconds). And the RICOH MP C6003 achieves both high productivity (60 cpm for b/w and color) and total electricity consumption (TEC) of just 2.55 kWh*4.
With these fresh energy-saving technologies, all of Ricoh’s new MFPs realize a TEC rate that is the best in the industry*5.

Efficient heating of fusing rollers
By giving the fusing roller a smaller diameter and thinner wall, and by placing the heater inside the roller, we achieved direct heating of the roller (belt) to improve heat transference and realize fusing at a lower temperature.

New projectors achieve network standby power consumption of less than 1W — a world first

projector

The RICOH PJ WX3340N/X3340N/WX4240N/ X4240N series of projectors boast high functionality and high image quality data as well as innovative energy-saving features and wired and wireless network connectivity. The series, launched in January 2013, contains proprietary network control technology that lowers standby power consumption to under 1W — a global first*6. This means the projectors comply with the 2019 standards of the European ErP Directive*7, the world's most stringent network standby power restrictions. Power is also saved on a large scale by automatic brightness control, which cuts lamp intensity by 70% (compared to conventional models) when there is no signal, and adjusts the lamp according to the ambient light level in the room and brightness of the image projected.

*7 The world's first restrictions to oblige manufacturers of energyrelated products to incorporate eco-design for the entire lifecycle of the product, from raw materials acquisition to disposal. The regulation becomes more stringent in stages (2015:6W, 2017: 3W,2019:2W).

Quantifying our "reduction contribution"

We established a scheme for quantifying values such as "reduction contribution" as a way to evaluate the lighter environmental impact our customers achieve by using Ricoh products and services/ solutions. During fiscal 2012, the total reduction was equivalent to 358,000 tons of CO2, which exceeds all CO2 emissions produced by the Ricoh Group's manufacturing sites around the world.
We will continue working on increasing our reduction contribution as part of our efforts to minimize the environmental burden of our business activities.

Evaluation targets and calculation method
Contribution through: Evaluation targets
Calculation method
Provision of energy-saving products Amount (CO2 equivalent) reduced through the introduction of models to customers' sites with enhanced energy-saving functions for Multi Function Printers (MFPs), printers and other equipment as well as CLARTE (LED lamps) to replace conventional lighting, among other energy-efficient products. Calculations are made using relevant internal data, including the number of units sold, and by referencing external materials, including methodologies for quantifying contributions to carbon emission reduction attributable to products and services, introduced by four Japanese electrical and electronics industry associations in its joint Low-Carbon Society Action Plan.
Solutions/services related to energy conservation Amount (CO2 equivalent) reduced through the introduction of energy efficient solutions/services to customers' sites, including RICOH Unified Communication System and duplex and multipage functions of MFPs.
Resource-conserving production process Amount (CO2 equivalent) reduced associated with procurement of raw materials and parts by lowering the input of new resources as a result of promoting reuse of recovered equipment, use of recycled materials, and production of more compact, lightweight models. Ricoh's LCA calculation results are used.
